A high-alkaline APC concentrate at pH 13 that lifts oil, grease and lubricants off workshop floors, out of the engine bay and off the lift in one pass. Not for pH-neutral coatings, synthetic-leather dashboards or anodised aluminium parts without a test patch first.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003eThe \u003cstrong\u003eKoch-Chemie Green Star Universal Cleaner\u003c\/strong\u003e works through a mix of surfactants, alkaline builders and corrosion inhibitors. With a pH between 12.5 and 13 it saponifies organic dirt — oil, grease, wax — turning it into soap compounds you can rinse off.\u003c\/p\u003e\n\n\u003cp\u003eThe surfactant shell then holds the loosened dirt in suspension so it doesn't dry back onto the panel when you rinse. That's why Green Star is the go-to APC in plenty of workshops and detailing shops that want a single cleaner for the engine bay, the lift, the workshop floor and exterior plastics — not because it's the best at any one of them, but because it hits the right balance between cleaning punch and material safety across that whole bracket.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-green-star-gs-universalreiniger_hero.png?v=1775995591\" alt=\"Koch-Chemie Green Star Gs bottle and canister on a concrete wall in front of a white Ferrari 296 GTB\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne chemistry, four dilutions.\u003c\/strong\u003e The mix ratio decides the job: 1:5 for the workshop floor and heavily oiled engine bays, 1:10 as a wheel pre-cleaner and bug remover, 1:20 for exterior plastics and rubber care, 1:50 for routine maintenance cleans in the customer reception.

A second pass lifts the residual dirt that was still in the pore bed. You won't get there mechanically with a pH-neutral interior cleaner.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e Never hit warm or sun-heated surfaces — once an engine block is past about 40 °C the alkaline solution flashes off and leaves water marks and limescale rings on painted covers. Engine-bay sequence: let the vehicle cool, mask intake and electronics, work bottom-up at 1:10, give it three minutes max, then rinse generously with a soft jet from the \u003ca href=\"\/en\/collections\/universalreiniger\"\u003euniversal cleaner\u003c\/a\u003e group. For repeat jobs grab a foam sprayer — it lays the 1:10 solution down more evenly than any hand pump and buys you 40 to 60 extra seconds of dwell on vertical surfaces.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1 to 5. 1 to 20. One canister, four jobs.\u003c\/h3\u003e\n\u003cp\u003eWith the Koch-Chemie Green Star Universal Cleaner the cleaning power isn't in the bottle, it's in the mix ratio. Skip the difference and you'll either clean too soft or wreck the material.\u003c\/p\u003e\n\n\u003cp\u003eFor the workshop floor you mix 1:5 in warm water, lay it down with a scrubber or single-disc machine, give it three minutes and pick it up with a wet vac. For the lift and the engine bay 1:10 is the safe standard: it lifts oil reliably without going at rubber steering boots or wiring-loom sheaths. For exterior plastics, trim and badly soiled wheel arches 1:20 is enough. The 1:50 dilution is for routine maintenance cleans in customer reception or on tiled floors — at that point you're past \"APC\" and into a mild alkaline cleaner with residual grease-cutting power.\u003c\/p\u003e\n\n\u003cp\u003eThe mistake shops almost always make with Green Star is the same one: too strong a mix, because \"stronger is better\" is stuck in the head. In practice 1:5 on an engine block gives you no measurable edge over 1:10 — what you get instead is higher chemical burn and the risk of overloading the corrosion inhibitor on aluminium. The real lever is dwell time: three minutes instead of two. Two passes instead of one. Never crank the concentration if the first pass came up short.\u003c\/p\u003e\n\n\u003cp\u003eTwo practical dosing workflows hold up day to day. Workflow one: canister straight onto a dosing station at the water tap, ratio set through the Venturi nozzle, application by foam sprayer or pressure sprayer. Workflow two for smaller shops: two labelled 500-millilitre spray bottles, one with the 1:10 mix for engine bay and wheel arch, one with 1:20 for exterior plastics. Mix both fresh every day — alkaline working solutions lose cleaning power inside 24 hours because CO₂ from the air slowly drops the pH.\u003c\/p\u003e\n\n\u003cp\u003eAn 11-kilo canister at a properly mixed 1:10 covers about 110 litres of working solution — that's roughly 40 engine-bay cleans or 15 workshop-floor passes over 100 square metres. For shops running two lifts and regular detailing the 22-kilo or 225-kilo drum pays off from three cleans a week, purely on the per-kilo price difference.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-green-star-gs-universalreiniger_closeup.png?v=1775995596\" alt=\"Koch-Chemie Green Star Gs label close-up with the pH 12.5 marking visible\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAlkaline. But not for everything.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Green Star Universal Cleaner has workshop DNA — it's not the right chemistry for delicate interior or coating surfaces.\u003c\/p\u003e\n\n\u003cp\u003eIt punches above its weight wherever organic dirt dominates: engine oil, gear oil, grease mist in the bay, soot on the workshop floor, brake-dust\/grease mixes in the wheel arches, road grime on commercial-vehicle frames. Bugs and bird droppings also soak off well with the 1:10 dilution before the actual wash. The alkaline pH saponifies the protein and turns a baked-on crust into a layer you can pull off — exactly where pH-neutral products would need you to scrub.\u003c\/p\u003e\n\n\u003cp\u003eWhere Green Star runs out of road is where the pH becomes the problem. On ceramic-coated paint every pass shaves a bit off the top bonding layer of the coating — for coating-sealed cars a pH-neutral shampoo or the Koch-Chemie \u003ca href=\"\/en\/products\/koch-chemie-mehrzweckreiniger-mzr-universalreiniger\"\u003eMultipurpose Cleaner \"Mzr\"\u003c\/a\u003e is the call.\u003c\/p\u003e\n\n\u003cp\u003eAnodised aluminium, matte aluminium and polished metal you never treat neat and you always patch-test in a hidden spot first. The corrosion inhibitor protects painted aluminium reliably, but on anodised surfaces it starts to struggle. Same goes for non-anodised magnesium rims and race parts — the alkaline side bites into the surface as soon as you push the dwell past two minutes.\u003c\/p\u003e\n\n\u003cp\u003eInside the cabin Green Star is plainly too aggressive: synthetic leather, Alcantara and coated dashboards don't take alkaline concentrates long-term, not even at 1:50. If you want one cleaner for both workshop and interior, that's a different chemistry.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-green-star-gs-universalreiniger_ergebnis.png?v=1775995602\" alt=\"Freshly cleaned Ferrari engine bay after a Koch-Chemie Green Star pass\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eGreen Star, Gs9 or Mzr. Your decision tree.\u003c\/h3\u003e\n\u003cp\u003eKoch-Chemie has three universal cleaners with overlapping use cases — the choice isn't about price, it's about what you're cleaning.\u003c\/p\u003e\n\n\u003cp\u003eThe classic Green Star is the workshop pick: hard-alkaline, high oil-carrying capacity, built for tough exterior and underbody work. The \u003ca href=\"\/en\/products\/koch-chemie-green-star-96-gs9-universalreiniger\"\u003eGreen Star 96 \"Gs9\"\u003c\/a\u003e is the milder follow-up with an optimised surfactant base and lower environmental load — it doesn't replace the classic Gs, it sits alongside it for detailers who work more often on private-customer cars with coatings and less on commercial frames. The Multipurpose Cleaner \"Mzr\" runs on completely different chemistry: weakly alkaline through to pH-neutral, built for interior, dashboards, carpets and upholstery. Gs cleans the engine bay, Mzr cleans the seats after.\u003c\/p\u003e\n\n\u003cp\u003ePractical rule for the buy decision: if the focus is the lift, the engine bay, the workshop floor and commercial-vehicle work, grab the classic Green Star in 11 or 22 kilos. If you mostly detail private-customer cars with ceramic protection and need the APC for wheel arches, bug removal and exterior plastics, the Gs9 is the cleaner fit. If you're after a cleaner for interior, carpet and upholstery, neither Gs nor Gs9 is the right answer — that's where the Mzr lives.\u003c\/p\u003e\n\n\u003cp\u003eFor the typical one-man detailer with a mixed customer base, the 11-kilo Green Star plus a 1-litre Mzr covers most of the actual workload: Gs for the whole exterior, the engine bay and floor cleans, Mzr for the interior. If you've got three separate APCs on the shelf — workshop cleaner, wheel cleaner, interior cleaner — this two-product setup halves the chemical cabinet and still cleans tighter.\u003c\/p\u003e\n\n\u003cp\u003ePack size tracks monthly throughput. The 1000-millilitre spray head is for the home detailer and the first test drive, not a working shop. From one vehicle a week with a proper exterior wash the 5-litre canister pays off; from three vehicles the 11-kilo container. 22 and 225 kilos belong in shops with a dosing station and steady commercial-vehicle work — for smaller outfits they're an unnecessary lock-in to one chemistry and harder to handle.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-green-star-gs-universalreiniger_detail.png?v=1775995607\" alt=\"Green Star working solution on the black plastic wheel arch of the Ferrari\" loading=\"lazy\" width=\"1200\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":48494630109519,"sku":"D1-KCX-291001","price":6.99,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":48725287960911,"sku":"D1-KCX-68037_2","price":13.7,"currency_code":"EUR","in_stock":true},{"title":"3x 1000 ml","offer_id":48725287993679,"sku":"D1-KCX-68037_3","price":20.34,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":48762352468303,"sku":"D1-KCX-291005","price":29.99,"currency_code":"EUR","in_stock":true},{"title":"11kg","offer_id":48494630142287,"sku":"D1-KCX-291011","price":56.49,"currency_code":"EUR","in_stock":true},{"title":"22kg","offer_id":49094546522447,"sku":"D1-KCX-291022","price":107.49,"currency_code":"EUR","in_stock":true},{"title":"225kg","offer_id":49094546555215,"sku":"D1-KCX-291225","price":1134.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-green-star-universalreiniger.jpg?v=1710769279"},{"product_id":"koch-chemie-gentle-snow-foam-gsf-reinigungsschaum","title":"Gentle Snow Foam \"Gsf\" Cleaning Foam","description":"\u003ch2 id=\"speakable-headline\"\u003epH-neutral pre-wash with the Koch-Chemie Gentle Snow Foam\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Gentle Snow Foam?

Tip more Gsf in but skimp on water and you get thin foam instead of a creamy blanket. Rule of thumb: fill the mixing bottle two-thirds with warm water, then dose 20 ml per litre. With soft water under 8 °dH bump the dose up a touch; with hard water from 14 °dH ease off — otherwise you end up with stringy foam that's a pain to rinse.\u003c\/p\u003e\n\n  \u003cp\u003eAnd always work onto wet, pre-rinsed paint. Dry paint means the foam grinds loose grit into the surface — the most common beginner mistake.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFoam lance, 20 ml, let the foam sheet off\u003c\/h3\u003e\n\u003cp\u003eYou lay the Gsf down on a wet, pre-rinsed car — never on dry paint, or you'll drag loose grit across the surface when you rinse. Knock the heavy dirt, bugs and bird muck off with the pressure washer first. A quick clear-water rinse beforehand takes 30 seconds and saves the clear coat from needless swirls.\u003c\/p\u003e\n\n\u003cp\u003eInto the foam lance goes 20 ml of Gsf per litre of water, which is about 1:50. Lay the foam on bottom to top so the run-off doesn't draw clean streaks through the dirt. Let it dwell 4–6 minutes, shorter in the sun — the foam mustn't dry on, or it'll leave streaks.\u003c\/p\u003e\n\n\u003cp\u003eThen rinse top to bottom thoroughly with clear water. Foam left in the panel gaps points to too little water pressure or too short a rinse. Whatever's still on the paint after that belongs to the \u003ca href=\"\/en\/collections\/autoshampoo\"\u003ecar shampoo\u003c\/a\u003e step of the two-bucket wash. The pre-wash doesn't replace the shampoo, it just cuts down how much grit ends up in your wash mitt.\u003c\/p\u003e\n\n\u003cp\u003eIf you haven't got a foam lance on the pressure washer, you can put the Gsf on with a pump sprayer instead — the foam comes out a lot flatter there and doesn't last as long. For a manual bucket wash, dose 50 ml in 10 litres of water, about two pumps from a trigger bottle. That's comfortably enough foam for a mid-size car, anything from a Golf up to an E-Class.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-gentle-snow-foam-gsf-reinigungsschaum_anwendung.png?v=1778625656\" alt=\"Koch-Chemie Gentle Snow Foam Gsf – foam lance spraying thick cleaning foam onto the 911 Turbo S\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003epH-neutral means your coating stays put\u003c\/h3\u003e\n\u003cp\u003eThe biggest difference from active pre-wash foams like the \u003ca href=\"\/en\/products\/koch-chemie-green-star-universalreiniger\"\u003eKoch-Chemie Green Star\u003c\/a\u003e is the pH. Gsf sits at 7.5, Green Star at around 11. On uncoated paint that doesn't matter; on a ceramic coating it does.\u003c\/p\u003e\n\n\u003cp\u003eStudies and hands-on testing show it: strongly alkaline cleaners above pH 10 break down the topcoat of ceramic coatings measurably faster. If you want to get 12 or 24 months of life out of your coating, you're better off with a pH-neutral weekly wash. The Gsf is built for exactly that — ongoing care instead of a one-off deep clean. The coating's hydrophobic effect stays intact, and the water beads after the wash just like it did on day one.\u003c\/p\u003e\n\n\u003cp\u003eWhere the Gsf hits its limits: baked-on bugs on the front end, tar spots on the sills, brake dust on the wheels or hardened pollen — it won't shift those.

The logic is simple: clean gently and often rather than aggressively and rarely. If you make the wash a fixed weekly habit, the Gsf takes you furthest.\u003c\/p\u003e\n\n\u003cp\u003eIt's less of a fit for body shops, seasonal cars coming off a long lay-up, or the spring clean after winter — there active foams with a higher pH have the edge, because the dirt is long past what the Gsf can dissolve. And if you don't own a foam lance and only run a pressure sprayer, the Gsf will give you foam, but never the consistency and dwell time of a proper lance on a pressure washer. For that case a spray-on pre-cleaner makes more sense.\u003c\/p\u003e\n\n\u003cp\u003eThe 1-litre bottle covers around 50 washes, the 5-litre can 250. If you look after more than one car or work in a detailing studio, the 5-litre container runs about 30 percent cheaper per wash. Pair it with a pH-neutral shampoo like the Koch-Chemie Nanomagic Shampoo or GYEON Q² Bathe+ for the two-bucket wash, and a drying towel to finish, and you've got the full weekly workflow for a well-kept car — from the first jet of water to the last drop, without ever attacking your coating.\u003c\/p\u003e\n\n\u003cp\u003eThe signature cherry scent is a matter of taste, but it rarely divides opinion — most detailers find it a lot more pleasant than the soapy standard smell of many competitor products. In closed garages or wash bays the smell doesn't linger after rinsing, which is a handy detail in day-to-day use.\u003c\/p\u003e\n\n\u003cp\u003eFirst time you run the Gsf, don't be stingy with the dose. 20 ml per litre is the floor for a visible foam blanket. On really dirty cars or with hard tap water, go a pump higher. The extra 4–5 cents a wash is nothing next to a weaker result.\u003c\/p\u003e\n\n\u003cp\u003eSame goes for the water pressure at the washer: under 100 bar the foam stays thin; from 130 bar it turns creamy and sits thick on the paint. Running a Kärcher K7 or similar, you can crank the lance to maximum foam output. With portable battery washers the foam comes out noticeably flatter — not a product fault, just a question of pressure.\u003c\/p\u003e\n\n\u003cp\u003eOne more tip from what we see at Detailing1: before each seasonal wash in spring and autumn, swap the Gsf for an active-foam wash with Green Star. That way no pollen film and no winter salt gets a foothold — the kind the pH-neutral foam can't shift over time.

An acid-free, viscous wheel cleaner from Koch-Chemie's workshop line that visibly dissolves brake dust and flash rust chemically via a red-violet colour change.

The active ingredient ammonium mercaptoacetate, a salt of thioglycolic acid, reacts with the iron(III) compounds in brake dust and lifts them off the wheel surface as a red-violet complex. The colour change isn't a marketing gimmick but the chemical reaction itself: where you see violet, iron is being converted right then and there. With a pH of 5–6 the formula stays gentle on painted and polished alloy wheels, chrome and steel. The high viscosity of 50 mPa·s means the product clings to vertical wheel faces instead of running straight off — so you get the full dwell time on the surface.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRed-violet colour change as a reaction indicator.\u003c\/strong\u003e No guessing how long to wait.

Warm surfaces let the gel dry on, and that leaves residue you then have to brush off. On heavily soiled wheels after months without cleaning, two short passes beat one long one: the active ingredient is chemically saturated after about 5 minutes. Just let it dwell twice for 3 minutes each and rinse in between.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCold wheel. Spray. Wait 2 to 5 minutes.\u003c\/h3\u003e\n\u003cp\u003eSpray the Magic Wheel Cleaner onto the cold, dry wheel — cover spokes, barrel, the rim edge and the wheel bolts evenly. Thanks to the syrup-like consistency the product clings vertically without you having to change how you work. Best to work bottom to top so you don't cover faces you've already wetted.\u003c\/p\u003e\n\n\u003cp\u003eAfter 30 to 60 seconds the colour change kicks in: first on spots with a lot of brake dust, then across the whole face. Red-violet streaks show you exactly where iron particles are being converted. After 2 to 5 minutes' dwell time the reaction is done — waiting longer gets you nothing, because the active ingredient is saturated after about 5 minutes. A common mistake is leaving the product on for 10 minutes hoping for better results. The opposite happens: the solution starts to dry on and leaves streaks.\u003c\/p\u003e\n\n\u003cp\u003eFinish by rinsing off with a strong jet of water from the pressure washer or garden hose, top to bottom. With heavy brake dust between tight spokes a \u003ca href=\"\/en\/collections\/zubehoer-felgenpflege\"\u003ewheel brush\u003c\/a\u003e can help spread the dissolved material — but not for scrubbing, just for touch-up. If you clean weekly to fortnightly, one pass usually does the job.\u003c\/p\u003e\n\n\u003cp\u003eA note on dosing: 500 ml lasts for about 10 full vehicle cleans. Per wheel, 40 to 50 ml is plenty. That works out to EUR 1.25 per full application — far more economical than the bottle price suggests, once you weigh it against the time spent mechanically scrubbing with less effective cleaners.\u003c\/p\u003e\n\n\u003ch3\u003eIt dissolves iron particles. Not tar.\u003c\/h3\u003e\n\u003cp\u003eThe Magic Wheel Cleaner is built precisely for one job: dissolving brake dust and flash rust chemically. The reaction between ammonium mercaptoacetate and the iron(III) ions in brake dust is the mechanism — anything that isn't iron doesn't get touched. That explains the colour change as a diagnostic tool: no colour means no iron, and no effect in that case isn't a shortfall of the product but the right answer to the dirt.\u003c\/p\u003e\n\n\u003cp\u003eAs a secondary use, the Magic Wheel Cleaner also works on paint as a flash-rust remover — especially handy on vehicles parked under industrial fallout or next to railway tracks. Fine iron particles settle there on the clear coat and react with the MWC formula just like they do on the wheel. Used before polishing, it boosts the adhesion of any following wax or ceramic coating, because the paint surface is genuinely contamination-free.\u003c\/p\u003e\n\n\u003cp\u003eWhere the MWC isn't the right product: baked-on tar, bitumen spots and oily soiling don't react with thioglycolate salts. For that you need a solvent-based tar remover. On badly neglected wheels with months-old brake dust that has worked its way into the pores, the stronger \u003ca href=\"\/en\/products\/koch-chemie-reactive-wheel-cleaner-rwc\"\u003eKoch-Chemie Reactive Wheel Cleaner\u003c\/a\u003e can be the better call — its acid system is more powerful, though not suited to every wheel material. The choice is clear: when safety on chrome and polished wheels matters, MWC. When you need maximum cleaning power and you're working with alloy painted and steel, RWC.\u003c\/p\u003e\n\n\u003cp\u003eA second case where no wheel cleaner in the world will help anymore: when the wheel is already visibly corroded or the clear coat has flaked off. At that point cleaning isn't the issue anymore — paint refurbishment is. The Magic Wheel Cleaner is a care product, not a restoration product.\u003c\/p\u003e\n\n\u003ch3\u003eYour standard for the regular wheel workflow\u003c\/h3\u003e\n\u003cp\u003eThe Magic Wheel Cleaner is the right call for anyone who keeps their wheels on a regular schedule and wants a product where they don't have to think about material compatibility. One product, one step, all wheels done. That's workshop logic — and that's exactly what the MWC is formulated for.\u003c\/p\u003e\n\n\u003cp\u003eIt really plays its strengths when you look after several vehicles with different wheel types or work on a fleet. Instead of three cleaners for three wheel types, one does it. It's weaker on extremely baked-on brake-dust residue from high-performance brake setups, or on wheels that haven't been cleaned for months. In both cases a second pass or a more aggressive product makes more sense than extending the dwell time.\u003c\/p\u003e\n\n\u003cp\u003eAs a complete solution the Magic Wheel Cleaner works best paired with a \u003ca href=\"\/en\/collections\/vorreinigung\"\u003epre-cleaner\u003c\/a\u003e like Koch-Chemie Vorreiniger B, applied as foam over the whole wheel before the MWC goes into the spokes. Finish with a \u003ca href=\"\/en\/collections\/reifenpflege\"\u003etyre dressing\u003c\/a\u003e on the flank — and the complete wheel workflow comes in at around 15 minutes per vehicle, if you stay on it every two weeks. That's the most common combo our customers buy: Vorreiniger B + Magic Wheel Cleaner. A precise, repeatable routine that works without scrubbing.\u003c\/p\u003e\n\n\u003cp\u003eHead to head with the acid-free classic SONAX FelgenBeast, the Magic Wheel Cleaner comes out ahead on two counts: the higher viscosity means longer contact time on the wheel, and the workshop formula is dosed stronger for commercial use. The FelgenBeast has a milder smell, though — if you work in a closed garage you'll definitely notice that. The Magic Wheel Cleaner is the workshop standard. The FelgenBeast is the garage all-rounder. Both do their job reliably; the question is which one fits your working environment.\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"500 ml","offer_id":48503670374735,"sku":"D1-KCX-425500","price":13.49,"currency_code":"EUR","in_stock":true},{"title":"2x 500 ml","offer_id":49725159276879,"sku":"D1-KCX-425500_2","price":29.38,"currency_code":"EUR","in_stock":true},{"title":"3x 500 ml","offer_id":49725159342415,"sku":"D1-KCX-425500_3","price":43.62,"currency_code":"EUR","in_stock":true},{"title":"10 liters","offer_id":48503670407503,"sku":"D1-KCX-425010","price":123.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-magic-wheel-cleaner-saeurefreier-felgenreiniger.jpg?v=1776410618"},{"product_id":"koch-chemie-allround-surface-cleaner-asc-allzweckreiniger","title":"Allround Surface Cleaner \"Asc\" All-Purpose Cleaner","description":"\u003ch2\u003eReady-to-use and streak-free through the cabin with the Koch-Chemie Allround Surface Cleaner\u003c\/h2\u003e\n\n\u003cblockquote\u003e\n  \u003cp\u003e\u003cem\u003eWhat is the Koch-Chemie Allround Surface Cleaner?

That's all the prep it takes.\u003c\/p\u003e\n\n\u003cp\u003eOn bigger panels like the dashboard, door cards or headliner, three to five squirts per part is plenty.

For vents, buttons and trim strips you spray onto the cloth first and work from there into the edges.\u003c\/p\u003e\n\n\u003cp\u003eTreat the headliner with extra care: only dampen the cloth, never spray the part directly. The headliner fabric mustn't get soaked, or the adhesive underneath lets go.

Badly yellowed plastics on the sill or a dried cola splash in the cup holder need more muscle too.

This ingredient reacts chemically with iron(III) oxides, the kind that show up as iron fallout on paint and as brake residue on wheels. The reaction becomes visible as a violet bleeding effect: wherever the solution turns colour, iron particles are being bound and lifted off the surface.\u003c\/p\u003e\n\n\u003cp\u003eThat sets the Rrr apart from acid-based iron fallout removers, which work faster but can leave irreversible damage on sensitive surfaces like polished aluminium or chrome wheels.

Wet panels dilute the gel and cut the contact time badly — the active ingredient gets rinsed away before it can react. Above 25 °C, hose the panel down briefly first, let it dry, then lay the Rrr on. Letting it dry out is the most common mistake: the gel leaves residue you then have to remove mechanically. Better two short passes of 3 minutes than one long one.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eSpray on, violet, rinse off. 3 to 6 minutes.\u003c\/h3\u003e\n\u003cp\u003eThe Reactive Rust Remover goes on undiluted onto the surface you want to treat and works there for 3–6 minutes. The violet colour change starts after about 10 seconds at the spots with the highest iron concentration.\u003c\/p\u003e\n\n\u003cp\u003eOn wheels, work from the bottom up so the gel doesn't run over areas you've already treated and stretch the dwell time there out of control. Cover spokes, barrel and wheel bolts. On paint, spray wide and even — bonnet and roof in passes, not in spots. Once the dwell time is up, rinse off with a strong jet of water. The Koch-Chemie spray head doses precisely and evenly, without dribbling or spitting.\u003c\/p\u003e\n\n\u003cp\u003eA common misconception: leaving it on longer than 6 minutes gets you no extra cleaning. The active ingredient ammonium mercaptoacetate is saturated after that — it has reacted with every iron(III) ion it can reach. If residue is still visible after the rinse, a second pass beats a longer dwell time. On the car care forum, detailers report that the first pass without a brush already dissolves 80 % of the contamination.\u003c\/p\u003e\n\n\u003cp\u003eFor stubborn spots between the spokes, a \u003ca href=\"\/en\/collections\/zubehoer-felgenpflege\"\u003ewheel brush\u003c\/a\u003e helps to spread the product — not to scrub. The chemical reaction does the work; the brush just carries the active ingredient into areas the spray jet can't reach directly. After rinsing, check the result visually: if you still see violet streaks, there's iron fallout sitting there. A third pass only pays off on paint — on wheels the leftover bit is usually quicker to take off mechanically.\u003c\/p\u003e\n\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-reactive-rust-remover-rrr-flugrostentferner_anwendung.png?v=1778626878\" alt=\"Koch-Chemie Rrr iron fallout remover being applied to a wheel\" width=\"1200\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\n\n\u003ch3\u003eThe Rrr dissolves iron fallout on paint. Baked-on brake dust, no.\u003c\/h3\u003e\n\u003cp\u003eThe Reactive Rust Remover reliably dissolves fresh to medium-age iron fallout — that's its core ground. On paint after parking next to railway lines, under industrial exhaust or along busy roads, the active ingredient reacts with the embedded iron particles and lifts them out of the clear coat without touching the paint structure. It works on glass too: iron fallout on the windscreen dissolves just as reliably as on paint.\u003c\/p\u003e\n\n\u003cp\u003eOn wheels it removes regular brake dust from standard pads in one pass. The colour change does the sorting for you: iron particles react violet, while organic muck like tar or oil doesn't change colour — so you see straight away what the Rrr can't shift. For tar spots you'll need a separate, solvent-based tar remover.\u003c\/p\u003e\n\n\u003cp\u003eA side effect detailers on the car care forum report: after cleaning, wheels show a bit of beading, the surface sheds water for a while. That comes from the high-performance surfactants in it (5–15 % anionic surfactants per the safety data sheet), which leave a thin protective film. This effect is no substitute for a dedicated wheel sealant, but it's a nice bonus with regular use every two weeks.\u003c\/p\u003e\n\n\u003cp\u003eWhere the Koch-Chemie Reactive Rust Remover hits its limits: iron fallout that's been sitting untreated on the paint for 6+ months has worked its way deeper into the clear coat. A single pass rarely does it here — plan for two or three. One customer on TrustedShops grumbled that \"iron fallout was still there\" — that typically happens with very old fallout that no chemical cleaner fully dissolves in one pass. After that, a \u003ca href=\"\/en\/products\/koch-chemie-rkb-reinigungsknete-mild-blau\"\u003eclay bar\u003c\/a\u003e can take off the last bits mechanically.\u003c\/p\u003e\n\n\u003cp\u003eFor extreme brake dust from performance brake setups or ceramic pads, the acid-based \u003ca href=\"\/en\/products\/koch-chemie-reactive-wheel-cleaner-felgenreiniger-750ml\"\u003eReactive Wheel Cleaner\u003c\/a\u003e is the stronger call — though with the material limits of an acid cleaner on polished or anodised aluminium. If you want safety on every surface, reach for the Rrr. If you want maximum cleaning power on tough, painted wheels, grab the Reactive Wheel Cleaner.

That's the most efficient workflow, because the Rrr clings and works best on a dry surface. If your car is ceramic-coated, you can use the Rrr without worry — pH 7.5 doesn't attack the coating. The opposite, really: iron fallout under a coating is the bigger problem, because it lodges there and undermines the coating from below.\u003c\/p\u003e\n\n\u003cp\u003eFor fleet use or commercial detailing, Koch-Chemie also offers the Rrr as a 5 kg canister and an 11 kg container. With regular use every 2–4 weeks, the 500 ml bottle is gone after 4–5 cars. The 5 kg canister pays for itself from the second month with daily use — provided you've set up a refill process with spray bottles.\u003c\/p\u003e\n\n\u003cp\u003eOn polished, unsealed aluminium the active ingredient can cause light tarnishing — that comes off with a metal polish, but a test on a hidden spot is a must. On painted wheels, clear coat and glass, the pH of 7.5 is harmless.\u003c\/p\u003e\n\n\u003cp\u003eGloves are still a must — the ammonium mercaptoacetate in the Rrr is classified as skin-sensitising under the CLP regulation (H317) and can trigger allergic reactions on repeated skin contact. Eye protection is recommended, as the product can cause serious eye irritation (H319). Use the Koch-Chemie Reactive Rust Remover every 2–4 weeks and you keep your iron fallout under control for good, and stop iron particles from working their way deeper into the clear coat.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-reactive-rust-remover-rrr-flugrostentferner_lineup.png?v=1778626889\" alt=\"Koch-Chemie Rrr 500ml and 11kg canister on a forecourt\" width=\"1200\" loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\n","brand":"Koch-Chemie","offers":[{"title":"500 ml","offer_id":48484362944847,"sku":"D1-KCX-68650","price":14.49,"currency_code":"EUR","in_stock":true},{"title":"2x 500 ml","offer_id":48618302734671,"sku":"D1-KCX-68650_2","price":31.34,"currency_code":"EUR","in_stock":true},{"title":"3x 500 ml","offer_id":48618302767439,"sku":"D1-KCX-68650_3","price":46.53,"currency_code":"EUR","in_stock":true},{"title":"5kg","offer_id":48762527285583,"sku":"D1-KCX-359005","price":57.49,"currency_code":"EUR","in_stock":true},{"title":"11kg","offer_id":48484362977615,"sku":"D1-KCX-359011","price":108.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-reactive-rust-remover-rrr-flugrostentferner_39372270-7c05-43d3-98f4-8c56b339d648.png?v=1778623449"},{"product_id":"koch-chemie-reactive-wheel-cleaner-felgenreiniger-750ml","title":"\"ReactiveWheelCleaner\" Wheel Cleaner","description":"\u003ch2\u003eThe must-have for spotless wheels is the Koch-Chemie Reactive-Wheel-Cleaner 750ml\u003c\/h2\u003e\n\u003cp\u003eWhen it comes to car care, clean, glossy wheels make or break the look of the whole car.

If the car gets washed one to four times a month, the paint is looked after normally but not ceramic-sealed, and there's no pricey coating-maintenance workflow running, As is the most economical and chemically sensible standard.\u003c\/p\u003e\n\n\u003cp\u003eThe Reactivation Shampoo \"Rs\" steps in where a ceramic coating is under 18 months old and you want to reactivate it on every wash. Rs has a pH-neutral character and contains polymers that bond to the coating's SiO₂ structure and rebuild the hydrophobic beading. For a plain wash with no coating involved, Rs makes no sense, the extra cost per litre only pays off when a coating actually exists.\u003c\/p\u003e\n\n\u003cp\u003eThe Ceramic Effect Shampoo \"Ces\" is the premium option with an extra SiO₂ boost; it brings a mini coating refresh to every wash and suits cars with no permanent coating that should still show hydrophobic behaviour between detailing sessions. If you get a professional sealant done every four to six months, Ces carries you past the Reactivation level in between, without laying down a coating of your own.\u003c\/p\u003e\n\n\u003cp\u003eRule of thumb for the buying call: As for uncoated paint and solid upkeep, Rs for existing coatings under 18 months, Ces for premium care without a coating.

In the foam cannon you mix roughly 100 ml of concentrate into 900 ml of water. The 10 kg drum works out to over 100 foam-cannon fills on paper — that's the point where you start thinking in litres in the garage instead of in spray bottles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e We often see people mixing a flat 1:50 in the foam cannon, then wondering why the foam looks thin or why streaks stay on the paint. Here's why: your pressure washer dilutes the mix again at the nozzle — usually by a factor of 15 to 25, depending on flow rate. That's the so-called Panel Impact Ratio, PIR for short. Quick bucket test: spray 1 litre of water through the lance, then measure the total water in the bucket. If 20 litres come out, your machine has a PIR factor of 1:20 — so you only need a pre-dilution of 1:5 in the lance to land the VDA-compliant 1:100 on the paint. And don't work in the sun, don't let it dry on, or even the best maths won't save you.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eFoam cannon, pre-diluted 1:10, three minutes' dwell time\u003c\/h3\u003e\n\u003cp\u003eThe classic application goes like this: car in the shade, paint dry or pre-rinsed, hook the foam cannon up to the pressure washer, pre-dilute the concentrate somewhere between 1:10 (winter, salt, baked-on brake dust) and 1:50 (summer, pollen, city grime) with warm water, and spray bottom to top.\u003c\/p\u003e\n\n\u003cp\u003eLet it dwell three to five minutes, then start at the top with the pressure washer and work down. Unlike the compressed-air pump sprayer — where the mix in the bottle is exactly the mix that hits the paint — the pressure washer adds water at the nozzle. In the pump sprayer the realistic dilution sits at 1:20 to 1:50, with no PIR effect, and the dwell time should run one to three minutes at most, or the foam dries on. The denser foam from the lance hangs longer, stays wet, and gives you the full five-minute window the VDA defines for Class A.\u003c\/p\u003e\n\n\u003cp\u003eIn the bucket you dose 1:300 — about 35 ml to 10 litres — and work with the microfibre mitt like you would with a regular shampoo. The upside over a classic pH-neutral car shampoo: the alkalinity breaks down baked-on summer grime and pollen film better. The downside: every contact wash with Af strips a little wax. If you're running a sealant, switch the contact phase over to the \u003ca href=\"\/en\/products\/koch-chemie-gentle-snow-foam-gsf\"\u003eKoch-Chemie Gentle Snow Foam Gsf\u003c\/a\u003e, which is certified wax-safe at pH 7.5.\u003c\/p\u003e\n\n\u003cp\u003eWhat we see day-to-day: the most common beginner mistake isn't the dilution, it's rinsing from too close. High pressure from 30 to 40 centimetres is plenty — get the nozzle in to 5 centimetres and you mechanically grind pollen and sand into the clear coat instead of washing them away. The foam has done its job; now the water jet should only carry things off.\u003c\/p\u003e\n\n\u003c!-- 📸 ANWENDUNG: Daniel mit Schaumkanone an Auto, dichter Sandelholz-Schaum auf Lack — d1_koch-chemie-active-foam-af-intensivschaum_anwendung.png --\u003e\n\n\u003ch3\u003eCarnauba gives way. Ceramic doesn't.\u003c\/h3\u003e\n\u003cp\u003eAt pH 9.5, Active Foam Af is clearly more alkaline than a classic pH-neutral shampoo, but moderate next to Bilt Hamber Auto-Foam, which runs at pH 13 and tears wax down on contact. On intact ceramic coatings (SiO2, often pH-stable from 2 to 13) Af is harmless — plenty of detailers even reach for it deliberately to lift the traffic film that masks the coating's hydrophobic behaviour over time.\u003c\/p\u003e\n\n\u003cp\u003eWith carnauba waxes it's a different story. A rare, correctly diluted pre-wash inside the VDA window won't strip the wax. But stand at the foam cannon with Af every single week and you'll break down the protective layer measurably faster than with a pH-neutral foam. The day-to-day rule: sealant younger than three months plus a weekly wash, then hands off Af and switch to the Gentle Snow Foam. Sealant refreshed every six months, or a ceramic coating, and Af makes a sensible deep pre-wash between your maintenance washes.\u003c\/p\u003e\n\n\u003cp\u003eWhat Af also won't shift: deep-set mineral water spots — for those the acidic \u003ca href=\"\/en\/products\/koch-chemie-reactivation-shampoo-rs\"\u003eKoch-Chemie Reactivation Shampoo Rs\u003c\/a\u003e is the right call, because it pulls limescale plugs out of the coating's pores. Baked-on bugs are too much for the foam as well. There you grab a dedicated bug remover locally, or the highly alkaline \u003ca href=\"\/en\/collections\/universalreiniger\"\u003eKoch-Chemie all-purpose cleaner\u003c\/a\u003e from the green line. Active Foam is an excellent pre-cleaner, not a specialist for every kind of dirt.\u003c\/p\u003e\n\n\u003c!-- 📸 ERGEBNIS: Lack mit Wassersaitenmuster nach Spülung, sauber und matt-feucht glänzend — d1_koch-chemie-active-foam-af-intensivschaum_ergebnis.png --\u003e\n\n\u003ch3\u003eDetailers, car washes and ambitious home users\u003c\/h3\u003e\n\u003cp\u003eActive Foam Af comes out of Koch-Chemie's pro range in Unna, yellow-coded like all the wash-chemistry products and available in pack sizes up to the 210 kg barrel. In rollover washes and self-service bays Af is an industry standard, because the thick foam visually signals a premium wash and the sandalwood scent works as an argument for higher programme prices.\u003c\/p\u003e\n\n\u003cp\u003eFor the home user, Af pays off once the foam cannon is already hanging off a strong enough pressure washer — you have to physically work out the PIR once yourself, because every pump draws differently. The 1-litre bottle is the easy way in for a single car and lasts about three to four months on a fortnightly pre-wash. The 10 kg drum starts to pay from the second car on, or in the detailing hobby, because the per-litre price drops noticeably and you just decant the concentrate into an empty spray bottle.\u003c\/p\u003e\n\n\u003cp\u003eDetailers and workshops usually reach for the 21 kg or 210 kg pack, because at 3 to 8 millilitres of usage per car in a rollover system the unit cost runs towards nothing. The 210 kg barrel goes out by freight forwarder with us — and yes, Active Foam is phosphate- and NTA-free, so it's cleared for biological greywater treatment plants, which is a must for commercial wash lines on a closed water loop.\u003c\/p\u003e\n\n\u003cp\u003eIf you've moved into a sealant routine and mainly want to hold the hydrophobic effect, switch your maintenance wash to the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-gentle-snow-foam-gsf\"\u003eGentle Snow Foam\u003c\/a\u003e and only pull the Active Foam out every few weeks for the deep pre-wash. If you keep an older car clean of everyday grime and have no wax layer to protect, you're better off with Af as your standard pre-cleaner than with any milder foam. In the current spring trend, where pollen and Sahara dust are measurably driving searches for car foam cleaner in the DACH region versus last year, this pre-wash logic matters more than ever.\u003c\/p\u003e\n\n\u003cp\u003eMaybe the most important Detailing1 note to finish on: the sandalwood scent isn't a marketing gimmick. Highly concentrated anionic surfactants smell sharp and biting on their own — the scent is an odour binder that makes working in enclosed spaces bearable. The fact that customers at wash lines link the smell with cleanliness and premium care and accept higher programme prices is the economic bonus layer on top. For your own garage it mainly means: ventilate well, don't work in a closed hall with no fresh air, and always label the spray bottle with its contents once you've decanted the concentrate from the 10 kg drum.\u003c\/p\u003e\n\n\u003c!-- 📸 LINEUP: Active Foam 1L + 10kg Kanister + Schaumkanone als Workflow-Stillleben — d1_koch-chemie-active-foam-af-intensivschaum_lineup.png --\u003e","brand":"Koch-Chemie","offers":[{"title":"1000ml","offer_id":49515049288015,"sku":"D1-KCX-282001","price":9.99,"currency_code":"EUR","in_stock":true},{"title":"2x 1000 mL","offer_id":49670747390287,"sku":"D1-KCX-282001_2","price":19.58,"currency_code":"EUR","in_stock":true},{"title":"3x 1000 mL","offer_id":49670747423055,"sku":"D1-KCX-282001_3","price":29.07,"currency_code":"EUR","in_stock":true},{"title":"10kg","offer_id":48762013548879,"sku":"D1-KCX-282010","price":48.49,"currency_code":"EUR","in_stock":true},{"title":"21kg","offer_id":49094689358159,"sku":"D1-KCX-282021","price":98.49,"currency_code":"EUR","in_stock":true},{"title":"210kg","offer_id":49094689390927,"sku":"D1-KCX-282210","price":1031.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-active-foam-af-intensivschaum.png?v=1726400580"},{"product_id":"koch-chemie-aktivwaesche-aw-aktiv-shampoo","title":"Aktivwäsche \"Aw\" Active Shampoo","description":"\u003ch2 id=\"speakable-headline\"\u003eAktivwäsche Aw works in the tunnel, in the lance and in the bucket\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eWhat is Koch-Chemie Aktivwäsche Aw?

Overdose it and you get a sticky dry residue on the paint, not better gloss. 50 millilitres to 10 litres of water is the mark where micelle formation runs clean: at that concentration the surfactant molecules form little foam spheres that capsule the dirt and carry it off when you rinse.

Both keep off the limescale marks that show up half an hour later when water droplets run down and evaporate. If you want to freshen the car up on top of that, follow Aw with a second cleaning workflow from the \u003ca href=\"\/en\/collections\/autoshampoo\"\u003eshampoo category\u003c\/a\u003e — pre-wash, snow foam or quick detailer, depending on what the car needs. Aw is the base, not the finish.\u003c\/p\u003e\n\n\u003cp\u003eIf you're running the foam lance, you mix Aw into the supply tank beforehand. The exact dilution depends on the foam insert and the water pressure — we start at 1:20 and dial it in after the first pass. Too thin means no all-over foam that clings long enough. Too thick means the concentrate drips off as a syrupy film and streaks later. Visual cue: the foam should sit on paint and glass for around 60 to 90 seconds, then come off top-down with the pressure washer.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-aktivwasche-aw-aktiv-shampoo.png?v=1778757009\" alt='Koch-Chemie Aktivwäsche „Aw\" in use in the bucket' loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAw attacks coatings. In the driveway it stays in the canister.\u003c\/h3\u003e\n\u003cp\u003eAt pH 7.5 Aktivwäsche Aw is almost neutral, but it carries a slightly alkaline kick — which is exactly what you want when the paint needs to be stripped clean before polishing or sealing. That same kick, though, attacks existing coatings, wax layers and SiO2 sealants over time. If you want to maintain a fresh ceramic coating rather than strip it, reach for Koch-Chemie NanoMagic Shampoo Nms at a mild-acidic pH 5.5, or the Glanzwachsshampoo Gw with wax content. Aw is the tool for cleaning, not for preserving.\u003c\/p\u003e\n\n\u003cp\u003eThe second limit is the dry time. Detailers abroad describe Aw as „tricky to finish washing the whole car before the concentrate dries on the paint\". That's true: in direct sun, on hot metal or at outside temperatures over 25 °C, Aw runs out of headroom. Shade, cool metal and working panel by panel aren't a suggestion, they're a must. Skip that and you pick up streaks and, in the worst case, spot etching on horizontal surfaces.\u003c\/p\u003e\n\n\u003cp\u003eThe third limit is legal: even though Aw is phosphate- and NTA-free and supports biological process-water treatment, washing a car with shampoo on private property is banned under the German Water Resources Act. The issue isn't the surfactants but the oil, brake dust and tar residue that would run into the groundwater with the rinse water. That's why Aw is only allowed at self-service bays with an oil separator or at wash systems with a process-water loop. Fines run into five figures depending on the state.\u003c\/p\u003e\n\n\u003cp\u003eIf you want to maintain an active ceramic sealant, reach for a mild maintenance shampoo from the \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie line\u003c\/a\u003e. If you can wash commercially or in a self-service box, Aw is the right tool. If you're parked privately in the driveway, Aw is the wrong product legally — no judgement, just the legal frame you should know before you crack the canister open.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-aktivwasche-aw-aktiv-shampoo.png?v=1778757009\" alt='Koch-Chemie Aktivwäsche „Aw\" — clean paint after the wash' loading=\"lazy\" style=\"max-width:100%;height:auto;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAw is a concentrate for detailers and wash-system operators.\u003c\/h3\u003e\n\u003cp\u003eAktivwäsche Aw is built for three types of user. Professional detailers who need a reliable paint pre-clean between polishing stations and sealing work, without the next week's coating layer getting attacked. Wash-system operators and fleet managers who have to cost it out at cents per vehicle and still want VDA Class A. And hobby pros with a workshop streak who work at the self-service bay or with their own lift and want one concentrate to last for years.\u003c\/p\u003e\n\n\u003cp\u003eAw is less of a fit for the classic Sunday washer in the driveway — both practically (dry time too short, uncontrollable without shade) and legally (Water Resources Act). If you're allowed to wash privately in the driveway because your local bylaw permits it in your area, check the local rules — they aren't uniform, they differ by state and municipality. When in doubt, take the wash to a self-service bay.\u003c\/p\u003e\n\n\u003cp\u003eThe 11 kg canister is the entry point for professional detailers with a single site. At one hand wash of a single vehicle a week, the container lasts around four years — in practice that means the concentrate rarely runs out, it ages first. The 21 kg keg pays off from the second detailing site or at higher workload. The 210 kg container is the wash-system size for tunnels with three-digit daily throughput.\u003c\/p\u003e\n\n\u003cp\u003eAw isn't a wow-gloss shampoo. It's the tool that preps the paint right on the mark for the next layer — whether that's a coating, a hot wax or simply clean dryness. Use Aw and put nothing on afterwards, and you're leaving performance on the table. That's pro logic: get it properly clean first, then put down exactly what you want.

Hot brake discs radiate well past 200 °C — if the cleaner hits that heat, the water in the dilution flashes off in seconds and you're left with highly concentrated potassium hydroxide standing on the paint, eating into the clear coat. Wait at least 15 minutes after parking up and wet it down generously.\u003c\/p\u003e\n\n\u003cp\u003eThe dilution follows the level of dirt: 1:10 is enough for weekly upkeep, 1:5 is the all-round figure for normal brake dust after two to four weeks of driving, 1:2 stays reserved for the extreme crusts on workshop vehicles. A pump sprayer with a foam nozzle like the \u003ca href=\"\/en\/products\/koch-chemie-foamer-bottle-schaumspender-150ml\"\u003eKoch-Chemie Foamer Bottle\u003c\/a\u003e or an iK Foam sprayer lays the solution down as a sticky wet foam that clings to the barrel and doesn't run off.

Longer does nothing: Awh isn't about reaction time, it's about chemistry. Leave it on too long and all you risk is drying-in, and dry edges on the clear coat are the result. If a spot isn't clean, top up the dose — don't let it dwell longer.\u003c\/p\u003e\n\n\u003cp\u003eFinish with a strong pressure jet top to bottom. Rinse the barrel and the spoke edges in a controlled way until no foamy veil runs off any more. Cold rinse water is a must: warm water speeds up drying-in inside the barrel, and a leftover cleaner film later pulls into the clear coat as a run mark. On the tyre sidewalls you can put the Awh straight to use — it lifts the brown antioxidant bloom (tyre-rubber blooming) at the same time and saves you the separate tyre cleaner.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-alkali-wheel-cleaner-awh-felgenreiniger-alkalisch_anwendung.png?v=1778768219\" alt=\"Daniel spraying Koch-Chemie Alkali Wheel Cleaner Awh 1:5 from the iK Foam Pro 2 Alk onto the wheel barrel\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSteel and painted aluminium yes, polished wheels no\u003c\/h3\u003e\n\n\u003cp\u003eAwh is cleared for standard steel wheels and alkali-resistant painted or powder-coated OEM aluminium wheels. As long as an intact clear coat protects the aluminium, the wheel behaves like perfectly normal paint and takes the cleaner with no trouble. That covers the vast bulk of the cars that sit on the lift at workshops and detailers every day — from lease returns to company cars.\u003c\/p\u003e\n\n\u003cp\u003eWhat Awh won't tolerate: raw aluminium, high-gloss polished aluminium, anodised wheels, magnesium wheels, uncoated forged wheels and chrome. On these surfaces the potassium hydroxide reacts with the metal in seconds. It oxidises the surface and leaves a milky, deeply etched patch — what's known as alkali burn.\u003c\/p\u003e\n\n\u003cp\u003eThis damage can't be washed off. The wheel is only saveable with hours of machine polishing at a specialist shop, and that runs into several hundred euros fast. In plain terms: on expensive multi-piece BBS RS wheels, on Porsche Fuchs wheels, on uncoated OZ forged wheels and on chrome lips, the sprayer stays in your hand. If you're not sure whether the wheel is anodised or painted, ask the manufacturer or test on an inconspicuous spot.\u003c\/p\u003e\n\n\u003cp\u003eFor exactly these sensitive wheel types, the pH-neutral \u003ca href=\"\/en\/products\/koch-chemie-magic-wheel-cleaner-mwc-felgenreiniger\"\u003eMagic Wheel Cleaner \"Mwc\"\u003c\/a\u003e or the reactive \u003ca href=\"\/en\/products\/koch-chemie-reactive-wheel-cleaner-felgenreiniger-750ml\"\u003eReactive Wheel Cleaner\u003c\/a\u003e is the right call.

Mwc or Reactive Wheel Cleaner for polished, anodised or chrome.

The mildly alkaline formulation cuts through grease, oil and dirt residue without harsh solvents — NTA-free and with no halogenated compounds.

For heavily soiled workshop and industrial floors, Koch-Chemie recommends a 1:40 to 1:120 dilution for machine or manual cleaning. So you dial in the dose to match how dirty the floor is, no swapping products. Using it couldn't be simpler: lay the concentrate down on the surface, let it dwell depending on the dirt, then rinse off with a scrubber-drier, a steam jet or a pressure washer.\u003c\/p\u003e\n\n\u003ch3\u003eSafety aspects — what \"safety cleaner\" actually means\u003c\/h3\u003e\n\u003cp\u003eThe term \"safety floor cleaner\" isn't marketing fluff, it's a technical classification: the product is fast-separating to ÖNORM 5105 and therefore suited to wastewater systems with light-liquid separators. In a car workshop or industrial hall that's often a legal requirement — cleaners mustn't overload the oil separator with surfactant concentrates. The Cosmo-Clean meets those requirements. The slip-resistant effect is another safety factor: floors that are still wet are a real accident risk when you're working with other cleaners — the Cosmo-Clean cuts that risk right down thanks to its special formulation.\u003c\/p\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e For detailing shops, the Cosmo-Clean really shines for cleaning the floor after polishing work, once polishing dust has settled onto it.

Laid down dry, the acid reacts too fast and bites into the surface harder than it needs to. A water pre-wet slows the reaction and spreads the concentrate evenly. The second common mistake: leaving it on too long. At pH -0.2, 30 to 90 seconds is plenty — after that the product belongs blasted off with a pressure washer. Letting it dry on causes material damage, not \"a little longer for more cleaning\".\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePre-wet, dilute 1:5, 60 seconds, rinse off\u003c\/h3\u003e\n\u003cp\u003eYou don't run the Fe neat. Standard dilution is 1:5 with water, up to 1:2 for extreme grime, up to 1:10 for light grime. That turns 11 kg of concentrate into 33 to 110 kg of working solution — one litre of ready solution costs between 0.72 and 2.40 EUR depending on the dilution.\u003c\/p\u003e\n\n\u003cp\u003eBefore you lay it down, hose the wheel down thoroughly with water. This pre-wet isn't optional. It slows the acid reaction, spreads the concentrate better and cuts the risk of streaking and spot material damage. Apply it with a low-pressure sprayer or brush from the bottom up, so run-off marks don't dry on. On vertical surfaces like wash-bay tiles, work in 1-metre lanes so the concentrate doesn't run over areas you've already done.\u003c\/p\u003e\n\n\u003cp\u003eThe order matters around the tyre. First mask the tyre sidewall or apply the dilution precisely — hydrochloric acid can bleach tyre markings. Then work the wheel itself, always from the same rotation position so no area gets missed. After rinsing, check it visually and only go for a second pass if there's grime still showing — with a properly dosed first pass that's rarely needed.\u003c\/p\u003e\n\n\u003cp\u003eDwell time is 30 to 90 seconds. As soon as you see a reaction (foaming, discolouration), work it straight away with the \u003ca href=\"\/en\/collections\/zubehoer-felgenpflege\"\u003ewheel brush\u003c\/a\u003e and rinse off thoroughly with a pressure washer. Several short passes beat one long one — the acid is saturated after 2 minutes max and does nothing but damage after that. PPE is a must: acid-resistant gloves, safety goggles, long-sleeved work gear. Rinse any splashes off your skin immediately with plenty of water.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-felgenreiniger-extrem-fe-felgenreiniger-sauer_anwendung.png?v=1776206205\" alt=\"Koch-Chemie Fe in use: low-pressure spraying onto a pre-wetted wheel\" loading=\"lazy\" width=\"900\" height=\"1200\"\u003e\n\n\u003ch3\u003eSteel wheel yes. Polished alloy no.\u003c\/h3\u003e\n\u003cp\u003eThe Fe is built for acid-resistant materials. Steel wheels, painted alloy wheels with intact clear coat, wash-bay tiles and commercial vehicles all qualify. Its cleaning power on baked-on brake dust from trucks, buses and construction machines is unmatched across the trade — no acid-free alternative comes close to that depth.\u003c\/p\u003e\n\n\u003cp\u003eThe chemistry is clear: hydrochloric acid dissolves iron oxide (Fe₂O₃) out of the brake dust and converts it into water-soluble iron chloride, which flows away with the rinse water. The same principle works on limescale (calcium carbonate), cement haze after building work and scale in wash bays. Inorganic grime dissolves in seconds; organic grime like tar, oil or insect residue isn't touched — that needs a solvent or surfactant cleaner.\u003c\/p\u003e\n\n\u003cp\u003eThe speed advantage is genuinely measurable. Acid-free wheel cleaners working via thioglycolate need 3 to 5 minutes of dwell time per pass and often two or three passes on baked-on brake dust. The Fe dissolves the same grime in 30 to 90 seconds in a single pass. In a detailing business with ten vehicles a day, that's a time saving of 60 to 90 minutes — costed as an hourly rate, the investment in the big pack pays for itself within a few weeks.\u003c\/p\u003e\n\n\u003cp\u003eWhere the Fe destroys on contact: polished aluminium with no paint protection, magnesium, chrome (attacked too, even lightly), zinc, marble, natural stone and all anodised surfaces. A pH of -0.2 is practically concentrated hydrochloric acid — this is industrial chemistry, not detailing care. Before the first use on any unknown surface, test a hidden spot, at least 5 cm² for 30 seconds, then rinse off thoroughly and check it visually.\u003c\/p\u003e\n\n\u003cp\u003eIf the wheels are polished, chromed or uncoated, grab the acid-free \u003ca href=\"\/en\/products\/koch-chemie-felgenblitz-saurefrei-fb-felgenreiniger\"\u003eKoch-Chemie Felgenblitz \"Fb\"\u003c\/a\u003e — it works through iron-binding agents instead of acid and is safe on all common wheel types. If the wheels are painted, carry little brake dust and you clean them regularly, an acid-free cleaner is enough too. The Fe only justifies itself when the brake dust is baked on and acid-free cleaners hit their limit.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-felgenreiniger-extrem-fe-felgenreiniger-sauer_ergebnis.png?v=1776206212\" alt=\"Koch-Chemie Fe result: clean wheel with water beading\" loading=\"lazy\" width=\"900\" height=\"1200\"\u003e\n\n\u003ch3\u003eShop, detailer, wash bay and depot\u003c\/h3\u003e\n\u003cp\u003eThe Fe is not a consumer product. It belongs in the shop, in the detailing bay and in the wash tunnel. Use it privately in your home garage and you're buying 11 kg of concentrate for a job an acid-free cleaner solves just as well in a 1-litre format — at far less risk to the wheel and to your own health.\u003c\/p\u003e\n\n\u003cp\u003eThe typical use cases are easy to name. Detailers with several vehicles a day need the fast, deep action on first-time clean-ups of neglected cars. Workshops with a tyre-change service use it during wheel swaps — above all in spring after the winter season, when road salt and baked-on brake dust sit together on the steel wheel.\u003c\/p\u003e\n\n\u003cp\u003eTruck and bus wash bays run it as their main cleaner against brake dust and road grime. Construction firms clean their vehicles of cement and limescale residue after a job. Building cleaners work with it on shop tiles, in maintenance halls and on industrial floor surfaces when limescale deposits, rust marks or cement haze need to come off.\u003c\/p\u003e\n\n\u003cp\u003eFor the buying decision it comes down to the pack. The 11 kg canisters are the right format for workshops with occasional need and detailers doing one or two vehicles a day — at 1:5 dilution they last for around 250 wheel sets. The 22 kg canister pays off for detailing businesses and smaller wash bays.\u003c\/p\u003e\n\n\u003cp\u003eThe 225 kg drum with pump system is the standard size for truck wash bays, large operations and building cleaners with daily use. The price per kg drops by about 12 percent from the 11 kg pack to the 225 kg drum — the bigger investment pays off from steady daily demand. If you're unsure which pack fits, start with the 11 kg canister and step up once you're going through three canisters a quarter.\u003c\/p\u003e\n\n\u003cp\u003eAs a complete setup you pair the Fe for the first clean with the acid-free Felgenblitz \"Fb\" for regular follow-up cleaning — that way you limit acid use to what genuinely can't be shifted acid-free. For tyre care afterwards, reach for a regular \u003ca href=\"\/en\/collections\/reifenpflege\"\u003etyre dressing\u003c\/a\u003e. Store in the original canister, frost-free, away from food, kept separate from alkaline cleaners (reaction risk).\u003c\/p\u003e\n\n\u003cp\u003eWithin the Koch-Chemie wheel cleaner family, the Fe sits at the top of the acidic line. If you need even more cleaning power and want to work with a three-acid blend, go for the \u003ca href=\"\/en\/products\/koch-chemie-triple-acid-star-ta-felgenreiniger\"\u003eTriple Acid Star \"Ta\"\u003c\/a\u003e.

The alkaline formula saponifies fatty acids and emulsifies oil residue rather than just pushing them around the surface.

Detail shops, fleet managers and independent workshops keep it as their standard interior cleaner — one concentrate for the whole fleet instead of a shelf full of specialty bottles.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e Never spray the Mzr neat onto a surface — pH 12.5 in the concentrate attacks soft plastics and pigments. Always dilute in the bottle first and start at 1:10. If that does the job, dial down to 1:20 next time. The most common mistake we see day-to-day: people run the dilution too strong and end up with white patches on dark plastics because the alkalinity has attacked the surface. Two passes at 1:10 give you a better, more even result than one pass at 1:5.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:10 on the headliner. 1:50 on the door handle.\u003c\/h3\u003e\n\u003cp\u003eKoch-Chemie Mzr works as a concentrate that you dilute fresh for every job. That sets it apart from ready-mixed \u003cstrong\u003einterior all-purpose cleaners\u003c\/strong\u003e like the \u003ca href=\"\/en\/products\/koch-chemie-multi-interior-cleaner-innenraumreiniger-750ml\"\u003eKoch-Chemie MultiInteriorCleaner\u003c\/a\u003e, which come at a fixed strength you can't change.\u003c\/p\u003e\n\n\u003cp\u003eFor a nicotine-stained headliner or greyed fabric seats you work at 1:5 to 1:10. Spray it on evenly, let it dwell for 1–3 minutes, then work it in with a soft detailing brush in circles. The Mzr lifts the dirt chemically, the brush pulls it out of the fibres. After that you extract the dissolved soil with a clean microfibre or a wet vac. On headliners the wet vac is non-negotiable — too much standing moisture softens the textile glue and the headliner starts to sag.\u003c\/p\u003e\n\n\u003cp\u003eFor everyday interior cleaning — dash, centre console, door cards — 1:20 to 1:50 is enough. At that strength the Mzr is gentle enough for most hard plastics. The surface comes out clean and there's no greasy film left behind.\u003c\/p\u003e\n\n\u003cp\u003eRight after that you can lay down a plastic dressing — the Mzr leaves no residue that would block adhesion. That's what makes it the go-to prep step before any dressing. Still: on soft-touch steering wheels and rubberised grips even the weakest dilution is a gamble. Grab a pH-neutral cleaner for those.\u003c\/p\u003e\n\n\u003cp\u003eOutside the cabin the Mzr earns its name too: workshop floors with oil stains, grimy industrial machines, weathered motorhome trim. For outdoor use go 1:5 to 1:10 and let it dwell 3–5 minutes. Hit it with a pressure washer or a brush, then rinse off.\u003c\/p\u003e\n\n\u003cp\u003eOne detail Koch-Chemie doesn't flag on the product page: the Mzr leaves a subtle, clean scent on the surfaces it cleans. Not an artificial air freshener — just noticeably less chemical than comparable industrial cleaners. In a smoker's car it won't mask the nicotine smell, but after the clean the cabin smells neutral instead of like cleaning chemicals. Sounds like a side-effect, but in the bay it matters when you're prepping cars for resale or hand-back.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_anwendung.png?v=1776198150\" alt=\"Headliner cleaning with diluted Koch-Chemie Mzr from an iK Multi TR 1 spray bottle in a Mercedes-AMG GT\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003ch3\u003eKoch-Chemie Mzr lifts nicotine films. Leather, it attacks.\u003c\/h3\u003e\n\u003cp\u003eOrganic dirt is the home turf of Koch-Chemie Mzr: greasy fingerprints, nicotine films, soot, ink stains and that typical grey ingrained look on light upholstery after two years of daily use. The alkaline formula handles those in one pass.\u003c\/p\u003e\n\n\u003cp\u003eThe colour shift from clean to dirty is instant on the Mzr — the microfibre after a wipe shows exactly what came out of the surface. Most dramatic on greyed light fabric seats: the first pass often pulls two shades of difference out. That's not a marketing line — it's the chemical effect of alkaline saponification breaking down the deep-set fat soiling that a neutral cleaner can't reach.\u003c\/p\u003e\n\n\u003cp\u003eKoch-Chemie positions the Mzr as an \u003cstrong\u003einterior all-purpose cleaner\u003c\/strong\u003e for cars, industry and building maintenance. The pack sizes tell you the same story: the 1-litre bottle sits next to 11 kg, 21 kg and 225 kg drums. This is a workshop cleaner that also works in the car interior. That origin is where the strength comes from — the Mzr is formulated for industrial grime, and that power follows it into the cabin.\u003c\/p\u003e\n\n\u003cp\u003eWhere the Mzr isn't the right tool: on genuine and synthetic leather with open-pore structure the alkalinity can dry out the surface and leave discolouration. Leather wants a pH-adjusted leather cleaner. On soft-touch plastics and rubberised surfaces like steering wheels or shift knobs it leaves dull patches. On painted or wrapped panels an alkaline cleaner has no business at all — even diluted 1:50, the pH still sits above 9. When you need an \u003ca href=\"\/en\/collections\/universalreiniger\"\u003eall-purpose cleaner\u003c\/a\u003e with no risk for sensitive materials, the Koch-Chemie ASC is the safer pick — ready-mixed, pH-neutral, surface-agnostic.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-mehrzweckreiniger-mzr-universalreiniger_ergebnis.png?v=1776196797\" alt=\"Headliner before and after cleaning with Koch-Chemie Mzr – nicotine grey on the left, deep black alcantara on the right\" width=\"900\" loading=\"lazy\"\u003e\n\n\u003ch3\u003eOne drum of Koch-Chemie Mzr. 200 litres of working solution.\u003c\/h3\u003e\n\u003cp\u003eThe Koch-Chemie Mzr pays back on yield. One litre of concentrate at 1:20 dilution gives you 21 litres of ready-to-use cleaner — enough for 15–20 full interior cleans. At €7.67 a litre that works out to under €0.50 per car. If you detail regularly, grab the 11-kg drum: at €77.75 you're at €7.07 per kilo and around 200 litres of working solution at 1:20.\u003c\/p\u003e\n\n\u003cp\u003eThe Mzr is built for detailers, workshops and serious hobby detailers who want a concentrate over ready-mixed bottles. If you only clean the interior occasionally and don't want to mess with dilution, grab the MultiInteriorCleaner ready to use. If you want flexibility — stronger for a smoker's cabin, weaker for the weekly wipe-down — the Mzr is the cheaper bet.\u003c\/p\u003e\n\n\u003cp\u003eFor day-in, day-out workshop use we run a Koch-Chemie tap on the 11-kg drum: dose the concentrate into the bottle, top up with water, done. The 1-litre bottle is the one to keep for mobile work and the detailing kit. Store both frost-free between 5 and 30 °C; sealed concentrate keeps for 24 months. Use any diluted mix within four weeks.\u003c\/p\u003e\n\n\u003cp\u003eOne safety note to finish: the Mzr is classified as corrosive (H314) and carries the signal word \"Danger\". In the concentrate, always wear gloves and safety glasses. At normal working dilutions of 1:10 to 1:20 the risk drops a lot, but you still want to avoid prolonged skin contact. The safety data sheet is on the product page for download.\u003c\/p\u003e\n\n\u003cp\u003eBottom line: the Koch-Chemie Mzr isn't an everyday quick-wipe cleaner. It's a tool for jobs where you need to clean deep — smoker's cars, used-car prep, workshop floors, industrial machines.

The active blend — C10–C13 n-alkanes, isoalkanes and cycloalkanes with under 2 percent aromatics — chemically breaks apart the molecule chains in bitumen and tar.

Available in 1 litre, 10 litre and 20 litre — plus a 2-pack and 3-pack when you need more. Alongside the alkane blend the formula carries a share of 2-butoxyethanol as a coupling agent, which improves how it wets a glass-smooth panel and keeps it working even at cooler ambient temperatures. For indoor use, run ventilation above three air changes an hour, and eye protection is a must for any overhead work.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical, not mechanical.\u003c\/strong\u003e You can't polish tar out — scrubbing drags the particles across the paint and leaves swirls behind.

That's the bit manufacturers and rivals rarely mention. If you do nothing after the tar comes off, you're left with unprotected paint that takes on fallout and water spots with no barrier. So always plan it in as the first step of a combo job: tar wash → normal wash with a pH-neutral shampoo → reseal with a \u003ca href=\"\/en\/products\/sonax-profiline-speedprotect-spruhversiegelung\"\u003espray sealant\u003c\/a\u003e or wax. For a spot job (the odd tar fleck on the sill) a quick detailer is enough as local protection.

You can see when it's working: the tar dissolves into brownish-black streaks and runs down vertical surfaces. As soon as that happens, rinse straight off with a strong jet of water or wipe it away with a clean microfibre cloth. A 1000 ml bottle covers roughly 4 to 6 full vehicle sides with moderate tar.\u003c\/p\u003e\n\n\u003cp\u003eOn bigger areas, don't let it dry — in direct sun or on hot paint above 25 °C the solvent flashes off too fast and leaves an oily film that only comes off at the next wash.

Carnauba waxes, synthetic polymer-based sealants and most quick detailers dissolve away on contact with the hydrocarbon blend. That's no fault in the product either, it's chemistry: what breaks down bitumen breaks down wax too, because both are built on similar organic molecule structures.\u003c\/p\u003e\n\n\u003cp\u003eFor the real world that means two things. First: every tar wash is followed by a full paint wash with a pH-neutral shampoo to neutralise the solvent residue. Second: the treated spot needs a fresh layer of protection.\u003c\/p\u003e\n\n\u003cp\u003eIf you're only dealing with small flecks on the side sill, you can follow up with a spot wax or detailer. If you're cleaning whole panels or the underbody, build the reseal into the workflow as a fixed step. SiO₂-based ceramic coatings usually aren't fully wrecked after a tar-wash treatment, but they lose noticeable hydrophobicity — a topper or detailer brings them back up to level.\u003c\/p\u003e\n\n\u003cp\u003eWhat Teerwäsche A isn't suited to: unpainted soft plastics, rubber seals and EPDM profiles. The solvent swells rubber over longer contact and can dull plastics. It mainly hits window seals, door rubbers and black plastic trim on older vehicles.\u003c\/p\u003e\n\n\u003cp\u003eDon't spray it over those surfaces broadly — if overspray happens, rinse it off with water within 60 seconds. On fresh wraps and PPF (paint protection film), test first on a hidden spot. Plenty of PPF coatings handle short contact times under 30 seconds but react sensitively to longer exposure.\u003c\/p\u003e\n\n\u003ch3\u003eWhen Teerwäsche A fits — and when it doesn't\u003c\/h3\u003e\n\n\u003cp\u003eTeerwäsche A is the right call when you're removing genuine road tar, bitumen spray after driving through roadworks, asphalt residue on wheel arches or dried-on oil films in the underbody area. It's also built for the regular cleaning of car-wash brushes and shop floors — wherever it's not paint cosmetics that's needed but real chemical solving power. In the spring season after winter it's standard for underbody prep, once tar-salt mixes have piled up over months.\u003c\/p\u003e\n\n\u003cp\u003eFor insect residue, though, it's not the first choice. Insect proteins are organic but structured differently — enzymatic cleaners like the \u003ca href=\"\/en\/collections\/insektenentferner\"\u003einsect remover\u003c\/a\u003e work more precisely and more gently on paint there. If you've got both at once — tar on the sill, bugs on the front end — treat both areas separately with the product that fits each. Trying to solve everything with one all-rounder usually ends in more rework. Same goes for tree sap and adhesive residue: both dissolve with the tar wash, but a dedicated tree-sap remover works cleaner.\u003c\/p\u003e\n\n\u003cp\u003eAs for pack size, the 1-litre bottle suits the private user and the occasional detailer planning one go per vehicle. The 2-pack and 3-pack bring the price per litre down by roughly 5 to 15 percent — worth it if there are several vehicles in the household or you want the season's supply locked in.\u003c\/p\u003e\n\n\u003cp\u003eThe 10 and 20 litre drums are trade sizes for reconditioning, underbody cleaning or fleet work — here the outlay only pays off from regular weekly use. For precise single-spot application the 1-litre bottle with the Canyon spray head stays the most ergonomic solution. The spray head delivers a precise cone rather than a mist and doses right onto the problem spot without wetting more area than needed.\u003c\/p\u003e\n\n\u003cp\u003eStore Teerwäsche A frost-free at room temperature. Once opened, the bottle stays stable for about 24 months as long as the cap is closed tight after use — hydrocarbon solvents evaporate slowly otherwise and the concentration drops.\u003c\/p\u003e\n\n\n\u003chr\u003e\n\n\u003cdiv class=\"care-guide\"\u003e\n  \u003ch3\u003eHow to use Koch-Chemie Teerwäsche A\u003c\/h3\u003e\n\n  \u003col\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrep.\u003c\/strong\u003e Move the vehicle into the shade, paint temperature under 25 °C. Never use Teerwäsche A on heated surfaces or in direct sun — the solvent then flashes off too fast and leaves an oily film. Have gloves (nitrile-resistant) and safety glasses ready. Pick a well-ventilated area; for pro use, make sure of at least three air changes an hour.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eIdentify the area.\u003c\/strong\u003e Tar and bitumen spots are typically found on the lower vehicle sections: side sills, wheel arches, bumpers, lower door edges. The affected area has to be dry — a wet surface dilutes the solvent and cuts the effect. If the vehicle was just washed, let it dry first.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSpray on.\u003c\/strong\u003e Apply Teerwäsche A undiluted with the Canyon spray head CHS-3AN or a solvent-resistant trade spray bottle onto the affected spot. Spray from about 15 to 20 cm in an even film, without flooding the surface. Work vertically: bottom to top, so the product runs down and wets the whole area.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLet it dwell.\u003c\/strong\u003e Leave it 30 seconds to 3 minutes. You'll see when it's working: tar dissolves into brownish-black streaks running down the surface. Don't let it dry — in warmer conditions above 20 °C go for shorter dwell times and a second application. Beyond 3 minutes, longer dwell brings no extra cleaning power.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRinse or wipe off.\u003c\/strong\u003e Steam the dissolved residue away with the pressure washer at around 120 bar from 30 cm. Or wipe it off with a clean microfibre cloth — after use, bin the cloth or wash it separately, it's saturated with solvent and tar.

Above 30 degrees paint temperature the cleaner flashes off before the dwell time is up — leaving dull streaks that only come off with polish. Before you start, move the vehicle into the shade or rinse it down with cold water first. In full summer sun, reach for the milder Pre-Foam efficient instead, which is far more forgiving with its 1-minute maximum dwell time.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003e1:30 for insects. 1:300 for high pressure.\u003c\/h3\u003e\n\u003cp\u003eDilution depends on how dirty the vehicle is and how you apply it. 1:30 to 1:50 for the pre-wash, 1:3 to 1:10 for heavily soiled wheels, 1:300 for self-service high-pressure units.\u003c\/p\u003e\n\u003cp\u003eFor the touchless pre-wash with a foam lance you work at 1:30 to 1:50. One litre of concentrate at 1:50 gives you 51 litres of ready-to-use solution — enough for roughly 20 to 25 cars in standard exterior care.\u003c\/p\u003e\n\u003cp\u003eThe foam lance should run at 0.8 to 1.2 litres per minute flow so the foam consistency is right and the cleaner clings to vertical panels long enough to do its job. Apply the pre-cleaner from the bottom up onto the cold, pre-wetted vehicle — that way you avoid run marks on unevenly dried panels. After 5 minutes dwell time at most (VDA Class A), rinse off thoroughly with the pressure washer.\u003c\/p\u003e\n\u003cp\u003eIn self-service wash bays, 1:300 is enough — that's the high-volume dilution and it cuts product use noticeably over a full year. For wheel cleaning you work at 1:3 to 1:10, sprayed straight onto the cold dry wheel, left to dwell for 1 minute at most, then rinsed. Important: don't use it on hot brake discs or warm wheels. The heat speeds up the reaction in an uncontrolled way and raises the risk of dulling on painted alloy wheels.\u003c\/p\u003e\n\u003cp\u003eFor wash tunnels with conveyor lines you typically run 1:100 to 1:200. Dwell time in the tunnel is usually 30 to 60 seconds, which still keeps you safely inside the VDA-B limit of 1 minute. The higher dilution cuts foam volume at the spray arch but keeps enough cleaning power thanks to the high active-ingredient concentration. With high vehicle throughput it pays to switch to the 225 kg container — a better price per litre of concentrate.\u003c\/p\u003e\n\u003cp\u003eFor copolymer de-waxing — stripping old preservatives before a fresh sealant — 1:5 to 1:10 is the right dilution.

No snow foam replacement.\u003c\/h3\u003e\n\u003cp\u003eThe Koch Chemie Vorreiniger B is not a mild foam pre-cleaner for coating-protected vehicles. pH 13.1 is workshop level — strong, uncompromising, but sensitive in use.\u003c\/p\u003e\n\u003cp\u003eIts strength is on heavily soiled vehicles with insect, bird-dropping and road residue after a long motorway run or after winter. It also works reliably on baked-on brake dust on steel wheels and on alkali-resistant painted alloy wheels. The foam is functional — not the show foam you get from classic snow-foam products, but a working foam that clings to vertical panels.\u003c\/p\u003e\n\u003cp\u003eNow the honest read on the limits. First, the Vorreiniger B is not friendly to active ceramic coatings. Used regularly on coating-protected vehicles it breaks the coating down faster than a pH-neutral pre-wash foam does. For vehicles with an active coating, the milder Pre-Foam efficient is the better call. Second, don't use it on polished aluminium or chrome surfaces — despite the corrosion inhibitors, pH 13.1 can dull untreated light metals. The inhibitors protect anodised alloy, not bare alloy.\u003c\/p\u003e\n\u003cp\u003eThird: it is not paint-surface gentle in the sense of a hand-wash chemistry. If you look after your new car with the two-bucket method and a mild car shampoo, you don't need a Vorreiniger B in the garage. Its job starts where hand washing no longer cuts it — on heavily soiled vehicles, commercial fleets, utility vehicles and construction machinery.\u003c\/p\u003e\n\u003cp\u003eProtective gear is a must, not optional. Nitrile gloves and safety glasses when mixing and applying. On skin contact, rinse straight away with plenty of water and remove residue with mild soap. Never leave the concentrate bottle open — the fumes from the alkaline cleaner irritate airways and mucous membranes on longer exposure. Close it well after use and store it frost-free and dark.\u003c\/p\u003e\n\u003cp\u003eThe material compatibility of the Vorreiniger B has clear limits. Allowed: steel, anodised aluminium, alkali-resistant painted surfaces, glass and standard automotive plastics. Not allowed: polished light metals, bare chrome surfaces, coloured anodised layers (risk of discolouration) and matt-painted surfaces without a protective film. When in doubt, test on an inconspicuous spot before the first application and watch it for 3 minutes — it costs little time and saves expensive damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-vorreiniger-b-vb-vorreiniger_ergebnis.jpg?v=1776199899\" alt=\"Koch-Chemie Vorreiniger B workshop-grade alkaline cleaner pH 13.1\" loading=\"lazy\" style=\"width:100%;height:auto;display:block;margin:1.5em 0;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWho the Vorreiniger B is for — from the pro to the home garage\u003c\/h3\u003e\n\u003cp\u003eThe Koch Chemie Vorreiniger B is built for pros and experienced home users with know-how in alkaline chemistry.

The first time you mix it, work with a calibrated measuring jug — go by eye and most beginners land far too concentrated, which loads the material needlessly and encourages streaking.\u003c\/p\u003e\n\u003cp\u003eIf you want a mild, coating-friendly pre-wash foam, you're better off with the Pre-Foam efficient. If you supply express wash lines with extremely short dwell times, reach for the Pre-Wash B. If you need the strongest cleaner for baked-on oil and grease residue on engines and chassis, take the Copo Star BMP-T. The Vorreiniger B is the all-round middle of the \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie range\u003c\/a\u003e — phosphate-free, double VDA-compliant, fast-separating to ÖNORM 5106 and therefore also approved for biological process-water treatment systems.\u003c\/p\u003e\n\u003cp\u003eAnd that last point is the real Detailing1 insight.

Two buckets. One layer.\u003c\/h3\u003e\n\u003cp\u003eThe Ces gives its best result with the two-bucket method: a wash bucket with 50 ml of Ces to 10 l of warm water, a separate rinse bucket with clean water, and a high-pile \u003ca href=\"\/en\/products\/koch-chemie-microfaser-handschuh-set-oktopus-waschhandschuh\"\u003emicrofibre wash mitt\u003c\/a\u003e. The second bucket keeps the dirt out of the wash bucket — that protects the paint from wash marks and makes sure every section gets worked with a clean foam concentration. Skip the second bucket and you drag the coarsest dirt particles over the paint again and again, picking up the swirls the Ces can no longer level out.\u003c\/p\u003e\n\n\u003cp\u003eAlways pre-rinse before the shampoo. A pressure washer or garden hose flushes off loose sand and road salt. Skip it and you drag the coarse particles across the paint with the mitt and pick up micro-scratches.\u003c\/p\u003e\n\n\u003cp\u003eWith heavy soiling or a layer of bugs, run a pre-cleaner as snow foam first, otherwise the Ces works past its care component. Cars with baked-on pollen or Saharan dust need that pre-clean, no way around it.\u003c\/p\u003e\n\n\u003cp\u003eAlways work on shaded, cool paint — not in the sun, not on a warm bonnet. Otherwise the foam dries on, leaves water spots, and the sealant effect builds up unevenly. Top to bottom, section by section, rinse each section on its own — the polymer film only forms during the rinse.\u003c\/p\u003e\n\n\u003cp\u003eThat's the key difference from pure cleaning shampoos: with those it doesn't matter how long the foam sits on the paint, with the Ces the result stands or falls on rinsing each section quickly. Foam the whole car and rinse only at the end, and you give away most of the sealant effect and get nothing but a standard cleaning result.\u003c\/p\u003e\n\n\u003cp\u003eOne last thing to dial in is the water temperature. Lukewarm water between 25 and 35 °C activates the SiO₂ component better than cold tap water, the foam builds faster and the care film bonds more evenly.

If you've never laid down a coating, the Ces still gives you a real, visible hydrophobic effect. If you already run a ceramic coating, every wash extends its lifespan by a few weeks, because the SiO₂ care component feeds the original sealant instead of degrading it.\u003c\/p\u003e\n\n\u003cp\u003eThe day-to-day reports are strong: on freshly waxed or coated paint the first wash brings a noticeably richer depth of gloss, with water beading off in 3–5 mm drops. Verified buyers at Trusted Shops regularly mention a visible beading effect and a pleasant berry-almond scent — a rarity from a pro-grade maker like Koch-Chemie.\u003c\/p\u003e\n\n\u003cp\u003eHonest about the limits: on unwaxed, uncoated paint the sealant effect lasts about 2–4 weeks, depending on the weather. In constant rain or with road salt in winter, shorter. If you want a permanent coating with 12+ months of lifespan, there's no getting around a proper ceramic coating.

For that, the Koch-Chemie Aktivwäsche AW is the stronger pick, because the Ces hits its limits faster with deeply worked-in brake dust and bug splatter.\u003c\/p\u003e\n\n\u003cp\u003eAs a complete wash workflow for this crowd it looks like this: pre-rinse with a pressure washer, snow foam for the pre-clean if needed, then a two-bucket wash with the Ces. After that, take it off section by section with the \u003ca href=\"\/en\/products\/soft99-max-wash-4pockets-trockenhandtuch\"\u003eSoft99 Max Wash drying towel\u003c\/a\u003e — no air-drying.\u003c\/p\u003e\n\n\u003cp\u003eOn the 1L versions, Detailing1 also offers the bundle with a dosing cap — it saves time on the weekly wash and prevents over-dosing. That's the most common mistake with the Ces day-to-day: more shampoo doesn't get you a better effect, just double the consumption.\u003c\/p\u003e\n\n\u003cp\u003eFor high-mileage drivers and multi-car households, the 5L container pays off after roughly 80 washes, because the per-litre price there runs about 30% below the 1L bottle. Wash weekly and it lasts you a good two years, with the extra cost earned back inside half a year.\u003c\/p\u003e\n\n\u003cp\u003eOne last Detailing1 insight for this crowd: the Ces gets better over time. On the first run on unwaxed paint the hydrophobic effect is visible but moderate. From the third or fourth wash a denser polymer film layers on, coat by coat.\u003c\/p\u003e\n\n\u003cp\u003eSuddenly water beads off in a normal summer rain as if the car had just been given a spray sealant. That's the point where most buyers switch to the Ces and never give it up — no miracle worker the first time, but a reliable build-up effect across the season.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-shampoo-ces-autoshampoo-versiegelung_lineup_8212300c-f401-47e5-ba76-e085ed4a6ee6.png?v=1778657751\" alt=\"Koch-Chemie Ceramic Effect Shampoo \" ces maintenance shampoo sealant litre and loading=\"lazy\" style=\"width:100%;height:auto;border-radius:8px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":49670904578383,"sku":"D1-KCX-811001","price":28.49,"currency_code":"EUR","in_stock":true},{"title":"1000ml + Dosing Cap","offer_id":54599151452495,"sku":"D1-KCX-811001+9998149","price":34.48,"currency_code":"EUR","in_stock":true},{"title":"2x 1000ml","offer_id":49670904611151,"sku":"D1-KCX-811001_2","price":57.8,"currency_code":"EUR","in_stock":true},{"title":"3x 1000 ml","offer_id":49670904643919,"sku":"D1-KCX-811001_3","price":85.82,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":49670904676687,"sku":"D1-KCX-811005","price":125.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-ceramic-effect-shampoo-ces-autoshampoo-versiegelung_d86bb773-4597-45d8-ad20-b521d3e869a4.png?v=1778623457"},{"product_id":"koch-chemie-rapid-rinseless-wash-rrw-waschen-ohne-abspuehlen","title":"Rapid Rinseless Wash \"Rrw\" — Rinseless Car Wash","description":"\u003ch2\u003eRinseless washing with Koch-Chemie Rapid Rinseless Wash \"Rrw\"\u003c\/h2\u003e\n\u003cp\u003eGet a fast, proper clean with the \u003cstrong\u003eKoch-Chemie Rapid Rinseless Wash \"Rrw\".\u003c\/strong\u003e This clever wash lets you clean your car top to bottom without rinsing off afterwards.

The water flashes off in seconds, the concentrate burns into the clear coat as a milky haze — and the only way back out is the polishing machine. Work in the shade, on a surface that's cool to the hand, and run two short passes rather than one long dwell. What we see day-to-day: etch one black bumper like that and you never forget the rule again.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eMix cool, dwell short, rinse hard\u003c\/h3\u003e\n\u003cp\u003eAlways lay the \u003cstrong\u003ecar pre-wash\u003c\/strong\u003e down diluted, on cool bodywork that hasn't heated up — work bottom to top and rinse it off completely with the pressure washer after a minute at most. That keeps the reaction in the safe zone.\u003c\/p\u003e\n\u003cp\u003eWhy pre-wash at all? The coarse grit you pick up on the road — silica dust, bug shells, salt crystals — acts like sandpaper the moment you start washing. A car pre-wash takes those particles apart through proteolysis and saponification: protein and grease lose their grip, the pressure washer carries them off before a sponge or brush ever touches the surface.\u003c\/p\u003e\n\u003cp\u003eHow strong you mix depends on the kit. In a pump sprayer — an IK pressure sprayer, say — the mix you make up hits the paint neat, so you deliberately go thinner here and meter it precisely.\u003c\/p\u003e\n\u003cp\u003eWith a foam lance it's the other way round: the pressure washer's water stream dilutes the bottle mix hard a second time, about tenfold. If you want a clean 1:100 on the paint through the lance, you mix the bottle at around 1:10 to start with. All that counts is what actually lands on the paint — plenty of people get that sum wrong and lay it down far too strong by accident.\u003c\/p\u003e\n\u003cp\u003eThe three dilution windows aren't arbitrary, they're working ranges: 1:30 to 1:100 for the paint pre-wash on a car, 1:4 to 1:20 for loose wheel grime and brake dust on alkali-resistant wheels, 1:2 to 1:15 for algae, oil film and biofilm on bay floors. The more delicate the surface, the thinner the mix and the closer your eye on the clock.\u003c\/p\u003e\n\u003cp\u003eBottom to top stops run-off concentrate streaking on dry panels. With heavy build-up — crusted bugs after a motorway run, a thick layer of salt in February — a second short pass beats leaving it to sit. Letting it dry is off the table: a dried alkaline film is exactly what leaves the marks afterwards.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-prewash-express-pe-vorreiniger_anwendung.jpg?v=1780346985\" alt=\"Car pre-wash being sprayed onto the dirty front end with a pro pressure sprayer\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eAnodised and bare aluminium stay off-limits\u003c\/h3\u003e\n\u003cp\u003e\"Pe\" is cleared for intact clear coat, steel wheels and alkali-resistant painted alloy wheels — not for anodised aluminium, bare metal or mirror-polished rims.

Aluminium is amphoteric — it dissolves in strong alkalis just as it does in acids. Let \"Pe\" hit a strip like that too strong or too long and the alkali eats into the layer, leaving milky-white, iridescent marks. They won't polish out; the strip has to be replaced. On bare or polished alloy the metal reacts on contact and dulls right off.\u003c\/p\u003e\n\u003cp\u003eOn intact clear coat, though, \"Pe\" is safe as long as you hold the minute. Modern clear coats are highly cross-linked polymers that shrug off a short alkaline spike with no trouble; dilute to 1:100 and the working pH on the paint drops into the 11 to 12 region anyway. Steel wheels and powder-coated, alkali-resistant alloy wheels take the stronger wheel dose — all that matters is the wheel isn't bare, anodised or mirror-polished.\u003c\/p\u003e\n\u003cp\u003eThe second hard line is heat. On a sun-warm bonnet the water in the solution flashes off in seconds, the alkali concentrates back up in spots and etches the clear coat. What's left is baked-in tide marks that only a machine polish removes. So the rule stands: never in full sun, never on hot metal.\u003c\/p\u003e\n\u003cp\u003eAnd \"Pe\" doesn't tell the difference between dirt and a protective layer. A product around pH 13 is as caustic as a drain cleaner and strips waxes, sealants and weaker coatings clean off. That's exactly why it's not a maintenance product.

If you want the classic, higher-foaming pre-wash for longer dwell times, the sister product \u003ca href=\"\/en\/products\/koch-chemie-vorreiniger-b-vb-vorreiniger\"\u003eVorreiniger B\u003c\/a\u003e is the better fit; \"Pe\" is the low-foam, express-tuned option in the \u003ca href=\"\/en\/collections\/vorreiniger\"\u003ePre-wash\u003c\/a\u003e range.\u003c\/p\u003e\n\u003cp\u003eThe numbers stack up mostly in volume work. A 23 kg drum makes around 2,300 litres of finished pre-wash solution at 1:100 — enough for hundreds of cars. Spread across a single wash the product cost barely shows; the real lever is the time the short dwell phase saves per car. For a handful of cars a month the 5 kg pack lasts a long while instead, with no concentrate ageing unused.\u003c\/p\u003e\n\u003cp\u003eThe pack sizes follow that logic: 5 kg to get started and for smaller operations, 23 kg as the standard drum for a running plant, 225 kg in the barrel for high-frequency wash tunnels with automatic dosing. The one thing no label spells out: the maximum dwell time isn't a suggestion, it's the safety limit. \"Pe\" is built for the machine that's done in 60 seconds.

The glycolic acid works on limescale like a clamp rather than a chemical crowbar: it wraps every calcium particle and makes it water-soluble instead of blasting it loose the way harsh mineral acids do. What that means for you: limescale rings wipe off without residue, and the Si-O-Si network of your ceramic coating — the tight protective lattice of silicon and oxygen that Koch-Chemie, GYEON or CarPro laid onto your paint — stays untouched. On top of that, the formula carries care polymers (trisiloxanes) that switch the hydrophobic behaviour of your existing coating back on in the same wipe.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spotless-ceramic-finish-scf-wasserfleckentferner_hero.png?v=1778701842\" alt=\"Black BMW M3 with water spots on the ceramic coating next to Koch-Chemie Spotless Ceramic Finish 500 ml\" loading=\"lazy\" decoding=\"async\" style=\"max-width:100%;height:auto;border-radius:12px;\"\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGlycolic acid lifts limescale like a clamp, not like an acid crowbar.\u003c\/strong\u003e Per kilogram of glycolic acid the formula binds around 612 grams of calcium carbonate — the acid locks every limescale ion into a water-soluble ring structure and rinses it away with the wash water.

At 18 °dH water hardness — standard in Munich, Stuttgart or Würzburg — plus summer heat, the minerals bake into the clear coat in 20 minutes. The pro rule: never let Spotless Ceramic Finish sit on the surface longer than three minutes. Wait ten minutes and you don't pull out any extra effect, you get the opposite — the acid dries on, the calcium ions you'd already bound drop back out as fine streaks, and you end up polishing afterwards instead of just wiping. The trick: a short second pass over the still-damp spot lifts stubborn limescale better than a longer dwell time on the first. Three minutes, wipe, check, repeat if needed.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003ePre-wash, Reactivation Shampoo, three minutes of Scf\u003c\/h3\u003e\n\n\u003cp\u003eYou spray \u003cstrong\u003eSpotless Ceramic Finish\u003c\/strong\u003e into a clean microfibre cloth and lay it down as a wafer-thin film on cool paint — never straight onto the panel and never in the sun.\u003c\/p\u003e\n\n\u003cp\u003eThe order is what counts. Before the Scf comes a pre-wash with the alkaline \u003ca href=\"\/en\/products\/koch-chemie-green-star-gs-universalreiniger\"\u003eGreen Star\u003c\/a\u003e, which lifts road grime touch-free, followed by a hand wash with the acidic \u003ca href=\"\/en\/products\/koch-chemie-reactivation-shampoo-rs-auto-shampoo-keramikversiegelung\"\u003eReactivation Shampoo\u003c\/a\u003e. Both belong to the official Koch-Chemie workflow for ceramic coatings. Only on clear, thoroughly rinsed paint does the Scf go to work.\u003c\/p\u003e\n\n\u003cp\u003eSpray the product into the cloth, not straight onto the panel. You want a thin, even film visible on the paint, not a dripping-wet carrier gel. Three minutes is the hard limit on dwell time — any longer and the film dries on and the glycolic acid loses its clamp effect, because the water in the carrier gel has evaporated. The consequence: bound calcium ions drop back out of the gel as streaks, and your car looks worse afterwards than it did before.\u003c\/p\u003e\n\n\u003cp\u003eAfter buffing off with a fresh short-pile microfibre cloth, you go over it with a second dry cloth if needed. The used cloth goes straight into the wash solution — the care polymer residue cross-links with the microfibres as it dries and makes the cloth permanently water-repellent if you just set it aside. What that means for you: a forgotten cloth is a lost cloth.\u003c\/p\u003e\n\n\u003cp\u003ePer 500 ml bottle you're looking at about two to four spritzes per body section, depending on how bad it is. For a full mid-size car reckon on 20 to 40 millilitres — that's about 12 to 25 applications per bottle, depending on section size and whether you work the whole surface or just spot-treat limescale rings.

Translated: what you missed over breakfast this morning, the Scf pulls off easily. What's been stuck on the car since the April pollen season needs a different tool.\u003c\/p\u003e\n\n\u003cp\u003eThe range of use is wider than the maker documents. Koch-Chemie explicitly names its in-house Cb0.01 and C0.02 coatings, but the glycolic acid is chemically compatible with GYEON Q² MOHS, MOHS+ and Pearl, with CarPro CQuartz UK 3.0, and with the Sonax Profiline Ceramic Coating just as well. Glass coatings like Soft99 Glaco or GYEON Q² View come through unharmed, and so do coated, painted wheel faces.\u003c\/p\u003e\n\n\u003cp\u003eThe clear limits. When limescale has sat on the paint for months and survived several summer-heat cycles, the minerals polymerise into a hardness that pH 3.5 just slides off. Fresh summer-rain limescale → Scf has it. Cement-hard baked-on crusts → knock them back mechanically first with a mild polish, or hit them spot-wise with a more aggressive cleaner at pH 1 to 1.5 — after that Scf comes back as your regular maintenance product.\u003c\/p\u003e\n\n\u003cp\u003eNever work on warm paint or in direct sun. Heat flashes off the carrier solvents in an instant, the acid concentration spikes locally, and you risk chemical etching in the clear coat. Day-to-day that means: plan at least 15 minutes between parking up and cleaning — the cheapest quality upgrade you can give yourself.\u003c\/p\u003e\n\n\u003cp\u003eAgainst other acidic water spot removers, Scf sits in its own niche. Sonax PROFILINE Waterspot Remover works at a similar pH around 3.0 but skips the pronounced gloss booster and delivers cleaner acid cleaning with no visible hydrophobic finish — you'll need a quick detailer afterwards. CarPro Spotless 2.0 runs a proprietary acid blend at pH 4.0 and is typically followed up with a separate detailer. Scf rolls both into one step: acid solving plus care polymer in a single wipe.\u003c\/p\u003e\n\n\u003cp\u003eOn coated wheel faces Scf also works as a targeted spot cleaner against mineral water marks. The glycolic acid lifts the limescale-and-brake-dust mix that clings to the wheel barrel after summer rain, without touching the wheel coating — a handy bonus job between the main paint applications. On coated glass like GYEON Q² View or Soft99 Glaco the product also clears stubborn rain streaks sitting on the coating, without wrecking the beading of the glass sealant.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spotless-ceramic-finish-scf-wasserfleckentferner_ergebnis.png?v=1778701859\" alt=\"Fresh water beading on the ceramic coating after applying Koch-Chemie Spotless Ceramic Finish\" loading=\"lazy\" decoding=\"async\" style=\"max-width:100%;height:auto;border-radius:12px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eFor coating owners in hard-water regions like Bavaria\u003c\/h3\u003e\n\n\u003cp\u003eIf you've put 800 to 1,500 euro into a professional ceramic coating and you wash in a hard-water region like Bavaria or Baden-Württemberg, treat Scf like an insurance policy. 16 euro per 500 ml bottle covers around 25 applications — about 0.64 euro per care run.\u003c\/p\u003e\n\n\u003cp\u003eGeography calls the shots here. In Munich, Stuttgart or Würzburg water hardness regularly tops 18 °dH, which means: over 180 milligrams of calcium and magnesium dissolved per litre of tap water. Wash with the home hose and don't dry within minutes and you produce hundreds of fine limescale rings in a single go. North German coastal cities with soft water under 8 °dH barely have the problem. For coating owners in the hard-water zone, Spotless Ceramic Finish is a standard care step after every hand wash — skip it and you slowly bury your own coating, wash by wash.\u003c\/p\u003e\n\n\u003cp\u003eAgainst the rest of the range the price makes the product a sensible insurance. More aggressive rivals like the Italian Innovacar 100% Scale work at pH 1.5 and pack sulphuric and hydrofluoric acid as a crowbar for extremely baked-on crusts — overkill for weekly upkeep on a coated car, perfect for a one-off deep decontamination. Scf positions itself as the caring maintenance product between wash cycles, with a built-in gloss boost instead of a blunt acid finish. More \u003ca href=\"\/en\/collections\/koch-chemie\"\u003eKoch-Chemie products\u003c\/a\u003e for the complete workflow are in the maker's category.\u003c\/p\u003e\n\n\u003cp\u003eThe ultimate trick for hard-water regions, one no guide spells out this clearly: instead of rubbing the car dry first and then spot-treating water marks, you spray Scf straight into the wet paint after the wash — as a drying aid. The glycolic acid neutralises crystallising salts in the very moment they form out of the evaporating water — before they can bake into the clear coat.\u003c\/p\u003e\n\n\u003cp\u003eThe care polymers push the residual water off the paint at the same time and lay a sliding film between clear coat and microfibre cloth. What that means for you: micro-scratches during drying drop drastically, because the cloth no longer drags against evaporating hard water but glides over a polymer lubricating film. You skip the separate drying step entirely: one job less per car, and at the same time the most effective protection against fresh water spots — this exact workflow runs in the official Koch-Chemie drying-aid tutorial, where the product goes on after the wash instead of before drying.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spotless-ceramic-finish-scf-wasserfleckentferner_lineup_829a1dd1-b12b-4d9c-8bbb-48ad055646fc.png?v=1778702753\" alt=\"Koch-Chemie Spotless Ceramic Finish 500 ml with Coating Towel on paving in the Detailing1 yard\" loading=\"lazy\" decoding=\"async\" style=\"max-width:100%;height:auto;border-radius:12px;\"\u003e\u003c\/p\u003e\n","brand":"Koch-Chemie","offers":[{"title":"500ml","offer_id":57637056708943,"sku":"D1-KCX-628500","price":14.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-spotless-ceramic-finish-scf-wasserfleckentferner.png?v=1778655960"},{"product_id":"koch-chemie-ceramic-effect-polish-cep-schaumpolitur","title":"Ceramic Effect Polish \"Cep\" Foam Polish","description":"\u003ch2 id=\"speakable-headline\"\u003eFoam polish Cep for hydrophobic gloss straight out of the car wash\u003c\/h2\u003e\n\n\u003cblockquote id=\"speakable-summary\"\u003e\n  \u003cp\u003e\u003cem\u003eThe \u003cstrong\u003efoam polish\u003c\/strong\u003e Ceramic Effect Polish \"Cep\" is a brush-activated premium concentrate for automatic car washes and gantry systems.

The result: smeary streaks on the windscreen, juddering wipers, the hydrophobic effect gone. The pro rule: before the first Cep run, recalibrate the pump to 5 to 10 ml, no exceptions, and check the dosing valve after 200 washes. If the conveyor stops for more than three minutes, hit the cars with the pressure washer too — polymer burn-in above 30 °C paint temperature is the most expensive warranty question a site operator can face.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCep only works when the brushes massage the paint\u003c\/h3\u003e\n\n\u003cp\u003eThe foam arch has to sit before the final brush or Swingtex station, or the water film won't break. Touchless machines give Cep too little mechanical friction, so the hydrophobic effect drops out completely.\u003c\/p\u003e\n\n\u003cp\u003eThe amino-siloxanes aren't passive layer-builders — they only react under pressure. The polymer's nitrogen anchors reach for the clear-coat surface like little magnets, and only once Swingtex or PE brushes press the foam into the paint do the siloxane chains line up and build the hydrophobic layer. What that means for you: without the paint massage the car comes out of the drying arch wet, the blower runs longer, and the meter ticks up with it.\u003c\/p\u003e\n\n\u003cp\u003eThe dosing pump puts out between 5 and 10 millilitres per car — no more. On older machines that ran 30 to 50 ml for other polishes, the balance between foam look and residue on the glass falls apart. A second lever: the paint surface has to stay cool, ideally under 30 °C. In direct summer sun at the exit, foamed-up Cep can dry on before the brushes reach it — and that leaves polymer spots you can only get off with the \u003ca href=\"\/en\/products\/koch-chemie-fine-cut-f601-schleifpolitur-fein\"\u003eFine Cut F6.01\u003c\/a\u003e cutting polish.\u003c\/p\u003e\n\n\u003cp\u003eSetting up a service station from scratch?

The surfactant keeps the amino-siloxanes in a foamable solution so the foam pattern stays stable. Day-to-day you notice it in the visual foam arch that operators and end customers both expect. If the foam goes too loose or collapses too fast, the surfactant helper is usually over-dosed — and Cep then gets diluted on the paint too quickly, the hydrophobic effect goes flat and the beading after the dryer disappoints.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-polish-cep-schaumpolitur_anwendung.jpg?v=1780347796\" alt=\"Foam from the Koch-Chemie Cep foam polish on dark paint during application\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003eCep protects, but it won't correct micro-scratches\u003c\/h3\u003e\n\n\u003cp\u003eThe Cep layer is a sacrificial layer until the next wash, not a 9H coating.

In practice that means: at 1,000 washes a month a Cep machine gets through five to ten litres of concentrate, against 50 to 70 kilos with a 50-to-70-gram product. That is containers, logistics, storage, drum changes across shifts — the micro-dosing isn't just product cost, it is storage and labour efficiency.\u003c\/p\u003e\n\n\u003cp\u003eThe most common mistake in practice: the conveyor stopping with the foam arch running. When the line stalls, Cep sits on the paint for more than five minutes. The industrial compatibility certificate from the German Automotive Industry Association holds exactly to 300 seconds — think of it as a TÜV-style industry seal that won't attack paint, chrome or plastic inside the defined window. Past that you risk polymer burn-in, especially in summer. The fix: a conveyor-stop SOP for the staff and an emergency pressure rinse in the drying zone.\u003c\/p\u003e\n\n\u003cp\u003eFor where it fits, the rule is simple. \u003cstrong\u003eMachine line with a paint massage → Cep.\u003c\/strong\u003e Hand wash or detail work → the lighter-concentrated \u003ca href=\"\/en\/products\/koch-chemie-ceramic-effect-shampoo-ces-autoshampoo-versiegelung\"\u003eCeramic Effect Shampoo \"Ces\"\u003c\/a\u003e from the same polymer family. Paint correction needed → a cutting or anti-hologram polish with a machine. Cep doesn't replace machine polishing — it is the final seal, not a cut and not a cleaner.\u003c\/p\u003e\n\n\u003cp\u003eCep is built as a pure B2B concentrate. In the machine room, gloves and safety glasses are mandatory kit and an eye wash has to be within reach. In the recycled-water loop Cep is unproblematic: micro-dosing of 5 to 10 ml keeps the active-ingredient concentration in the recycled water below the threshold for the treatment micro-organisms. That is also why Koch-Chemie explicitly clears Cep for biological process-water treatment systems — over-dose it and that clearance is void.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-polish-cep-schaumpolitur_ergebnis.jpg?v=1780347805\" alt=\"Hydrophobic water beading after Koch-Chemie Ceramic Effect Polish Cep on black paint\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e\n\n\u003ch3\u003e20-litre canister for pro machines, not for the home wash\u003c\/h3\u003e\n\n\u003cp\u003eCep is aimed at car-wash operators, gantry systems, dealerships with their own machine and specialised B2B detailers. For a hobby detailer without a dosing pump, the canister simply isn't practical.\u003c\/p\u003e\n\n\u003cp\u003eThe 20-litre pack size is built for machines with diaphragm dosing pumps. Run a gantry at a dealership and one canister covers three to six months depending on volume. A self-service bay only benefits if the dosing gear is fine enough to calibrate — most self-service foam arches sit around 30 ml, outside the Cep spec.\u003c\/p\u003e\n\n\u003cp\u003eAn established best practice from the pro side: Cep as a booster on cars already sealed with a real ceramic base like Ceramic Allround C0.02 or Ceramic Body Cb0.01. The gentle amino-siloxane top-up reactivates the beading on an older coating that has gone flat from traffic film. A fleet on a Cb coating plus a regular Cep pass typically holds its showroom gloss six to nine months longer than a fleet without that combo.\u003c\/p\u003e\n\n\u003cp\u003eRecalibrating an old machine? Best to plan the first 50 washes as a test batch: start the pump at 7 millilitres, then check the beading after the drying arch on 10 random cars. If the water sheets off flat instead of in clean beads, you are either short on foam-arch pressure or the brush contact time is too short. Only then touch the dosing. Put another way: the chemistry isn't the lever, the machine mechanics are. Cep's polymer concentration is already dialled in — everything you do as an operator tunes the activation mechanics.\u003c\/p\u003e\n\n\u003cp\u003eThe trick the manufacturer's brochure doesn't spell out: the polymer layer impregnates the machine's brushes so well that their service life climbs about 20 percent with consistent Cep use. On a typical car wash with two gantry-brush sets a year, that saves a four-figure sum in brush swaps and service work — the biggest hidden bit of economics in this concentrate, and the real reason pro sites rarely give Cep back once they have calibrated their pumps properly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-ceramic-effect-polish-cep-schaumpolitur_lineup.jpg?v=1780347979\" alt=\"Koch-Chemie Ceramic Effect Polish Cep 20-litre canister on the workbench\" loading=\"lazy\" style=\"width:100%;height:auto;border-radius:4px;\"\u003e\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"20 liters","offer_id":57637057298767,"sku":"D1-KCX-683020","price":350.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-ceramic-effect-polish-cep.png?v=1778655965"}],"url":"https:\/\/detailing1.nl\/en\/collections\/koch-chemie-autowaesche.oembed?page=3","provider":"Detailing1","version":"1.0","type":"link"}
