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. Works on alloy painted, alloy polished, chrome and steel. Not for baked-on tar or bitumen spots.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eThe Koch-Chemie Magic Wheel Cleaner\u003c\/strong\u003e — usually just called \"MWC\" in-house — is an acid-free wheel cleaner from Koch-Chemie's workshop line. 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. You see in real time where iron particles are reacting and when the reaction is done. That kills two classic mistakes: rinsing too early (cleaning unfinished) and leaving it on too long (product saturates and dries on).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSyrup-like viscosity for vertical cling.\u003c\/strong\u003e At 50 mPa·s the Magic Wheel Cleaner is thick enough to stay in the spokes and on the wheel flank without dripping straight to the ground. That sets it apart from watery wheel cleaners where half the product would run off unused.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne cleaner for your whole wheel collection.\u003c\/strong\u003e Alloy painted, alloy polished, chrome and steel — the pH of 5–6 is mild enough to use even on high-gloss polished forged wheels. On anodised or matte-coated wheels, test on a hidden spot first.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDay-to-day from Detailing1:\u003c\/strong\u003e Always spray onto a cold, dry wheel — never in direct sun, never onto warm brakes after a drive. 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-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.

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.

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.
