A pH-neutral rim cleaner with gel formula and optical active indicator from TUGA Chemie that chemically dissolves brake dust, rust film, and metal particles on all common rim types. Not suitable for baked-on brake dust after months of neglect or tar and bitumen contamination.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eAlu-Teufel Spezial\u003c\/strong\u003e is a rim cleaner gel from TUGA Chemie that works with the active ingredient sodium thioglycolate: The gel binds iron(III) compounds in brake dust and chemically dissolves them from the rim surface — without attacking the rim itself. This is visible by the color change from green to reddish-violet as soon as the gel reacts with iron particles. TUGA Chemie has been producing Alu-Teufel in Osnabrück since the 1970s and has since further developed the formula to today's gel consistency.\u003c\/p\u003e\n\n\u003cp\u003eIn addition to the main active ingredient sodium thioglycolate, the gel also contains phosphonates and non-ionic surfactants that emulsify organic dirt such as oil and rubber residues from brake pads. While the thioglycolate chemically attacks the iron compounds, the surfactants dissolve the rest. This combination makes a separate pre-cleaner unnecessary for normal contamination. The product is biodegradable according to German detergent law and contains no acids or alkalis in the classical sense — the pH value of 5.8–6.3 is in the skin-neutral range.\u003c\/p\u003e\n\n\u003c!-- 📸 FOTO 1: HERO-BILD hier — Produkt in der Szene\n     Alt-Text: \"Alu-Teufel Spezial Grün Felgenreiniger-Gel vor Fahrzeug\" --\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor change shows you where brake dust is.\u003c\/strong\u003e The gel changes from green to reddish-violet within 60–90 seconds as soon as it dissolves iron particles. You see in real-time which areas are reacting and which are already clean. This prevents two common mistakes: rinsing too early on heavily soiled areas and unnecessary reworking on areas that are already clean.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne cleaner for all rim types.\u003c\/strong\u003e pH value 5.8–6.3, i.e., in the skin-neutral range. Polished aluminum, painted aluminum, steel, chrome, multi-part rims — none of these surfaces are attacked. This saves you separate cleaners and the risk of using the wrong one on the wrong rim. Only restriction: For matte or anodized rims, test on a hidden area first.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGel adheres where liquid runs off.\u003c\/strong\u003e The gel consistency adheres to vertical spokes instead of immediately running into the rim well. This gives you an even exposure time over the entire rim. Approximately 50 ml per wheel is sufficient for a complete cleaning — which results in about 20 complete sets of rims for the 1-liter bottle, and over 100 for the 5-liter canister.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003ePractical tip from Detailing1:\u003c\/strong\u003e Always spray onto the cold, dry rim — do not pre-rinse. Water dilutes the gel by 30–50 percent and the color change will be uneven. At temperatures above 25 °C, let the rim cool briefly in the shade, otherwise the gel will dry before it has reacted. The result: stubborn residues that you then have to remove mechanically. Spray from bottom to top so that runoff marks do not run over already cleaned areas.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCold rim. 3 minutes. Rinse.\u003c\/h3\u003e\n\u003cp\u003eWithin 3–5 minutes of exposure time, the gel completely dissolves regular brake dust from the rim surface. Spray on, wait for color change, rinse with a strong jet of water — that's the complete process.\u003c\/p\u003e\n\n\u003cp\u003eSpray the gel evenly onto the cold, dry rim. Include spokes, rim well, and wheel bolts, working from bottom to top. Within 60–90 seconds, the color change begins: reddish-violet streaks show you where iron particles are dissolving. The full exposure time is 3 minutes, maximum 5. No longer — sodium thioglycolate is saturated after about 5 minutes.\u003c\/p\u003e\n\n\u003cp\u003eFor the gaps in multi-part spokes, a \u003ca href=\"\/en\/products\/tuga-chemie-detailing-felgenpinsel-alu-teufel-spezial-gruen\"\u003erim brush\u003c\/a\u003e is recommended to spread the gel into hard-to-reach areas. Not for scrubbing, just for working it in. Afterwards, rinse with high pressure or a strong jet of water from top to bottom.\u003c\/p\u003e\n\n\u003cp\u003eA common misconception: Longer exposure time does not lead to more cleaning power. The active ingredient reacts completely within the first 3–5 minutes. If you want to help with heavy brake dust, a second pass is better. If you clean every two weeks, one pass is almost always enough. If you only clean every 4–6 weeks, you should expect two passes.\u003c\/p\u003e\n\n\u003cp\u003eImportant for the spray head: The 1-liter bottle has a standard trigger that becomes stiffer at low temperatures below 5 °C. Warm the bottle briefly in your hand beforehand. When decanting into the 5-liter container, spray via an empty bottle with a foam head — the gel foams slightly and adheres even better to the rim. In midsummer, however, never work in direct sunlight. From 30 °C ambient temperature, the gel on a sun-exposed rim has less than 90 seconds before it dries.\u003c\/p\u003e\n\n\u003c!-- 📸 FOTO 2: ANWENDUNGS-BILD passend zu H3 #1\n     Alt-Text: \"Alu-Teufel Spezial Grün Anwendung auf Felge mit Farbumschlag\" --\u003e\n\n\u003ch3\u003eBrake dust dissolves the gel. Tar does not.\u003c\/h3\u003e\n\u003cp\u003eThe gel reliably dissolves regular brake dust from standard brake pads — that's its core area. The active indicator not only shows you where dirt is, but also what kind: Iron particles react reddish-violet, organic contaminants such as tar or oil show no discoloration.\u003c\/p\u003e\n\n\u003cp\u003eAs a secondary application, the gel also works as a rust film remover on paint. After parking next to railway tracks or under industrial exhaust, fine iron particles accumulate on the paint surface, which feel like rough spots. Spray on, wait for color change, rinse — this works just as safely on clear coat as on rims. Rust film is one of the underestimated paint damages: If it remains on the paint for more than 2–3 weeks, the iron eats into the clear coat and leaves craters that only polishing can remove.\u003c\/p\u003e\n\n\u003cp\u003eWhere the gel reaches its limits: Baked-on brake dust after 6+ months without cleaning sits deep in the pores of the rim surface. Here, the pH-neutral gel does not have enough chemical power. In this case, the acidic \u003ca href=\"\/en\/products\/tuga-chemie-aluminium-teufel-rot-felgenreiniger\"\u003eAluminum-Teufel Rot\u003c\/a\u003e is the stronger choice — but only on painted rims, not on polished aluminum or chrome. Tar and bitumen stains do not react at all with sodium thioglycolate. For that, you need a solvent-based tar remover.\u003c\/p\u003e\n\n\u003cp\u003eAs a rule of thumb: If you are looking for a gentle all-rounder for regular care, this gel remains the right choice. If you need maximum chemical power and accept the material limitations of an acid cleaner, reach for Aluminum-Teufel Rot.\u003c\/p\u003e\n\n\u003cp\u003eThe difference is chemically simple: Alu-Teufel Spezial works at pH 5.8–6.3 and only attacks iron compounds. Aluminum-Teufel Rot works in the acidic range and also dissolves mineral crusts that have worked their way into the rim over months. The price for this power: On unprotected aluminum rims, acid can leave irreversible stains.\u003c\/p\u003e\n\n\u003c!-- 📸 FOTO 3: ERGEBNIS\/DETAIL-BILD passend zu H3 #2\n     Alt-Text: \"Alu-Teufel Spezial Grün Ergebnis saubere Felge nach Reinigung\" --\u003e\n\n\u003ch3\u003eTest winner for regular rim care\u003c\/h3\u003e\n\u003cp\u003eIn the AUTO ZEITUNG rim cleaner test, the gel achieved 91 out of 100 points and the grade \"Very good\". It is the right choice for anyone who cleans their rims every 1–4 weeks and doesn't want to worry about material compatibility.\u003c\/p\u003e\n\n\u003cp\u003eThe product performs particularly well in everyday use with multiple vehicles or in fleets, where various rim types are to be covered with one cleaner. You grab the bottle, spray, rinse. No thinking about whether your rims are polished or painted, no risk for chrome rims, no fear of stains on the paint.\u003c\/p\u003e\n\n\u003cp\u003eThis simplicity is the real advantage over stronger, but more limited, acid cleaners. The gel is less suitable if you are primarily battling extreme brake dust from racing brake systems or only clean your rims every few months. In both cases, you need more chemical power than a pH-neutral cleaner can provide.\u003c\/p\u003e\n\n\u003cp\u003eThe yield is approximately 50 ml per set of rims. For the 1-liter bottle at €12.99, that comes to €0.65 per cleaning process for all four wheels. The 5-liter container reduces the price per application to under €0.45. With bi-weekly cleaning, the 5-liter canister lasts over a year.\u003c\/p\u003e\n\n\u003cp\u003eFor a complete wheel workflow, combine the gel with a \u003ca href=\"\/en\/collections\/tuga-chemie-felgenbuerste-felgenpinsel\"\u003erim brush\u003c\/a\u003e for the rim well and Shampoo-Teufel for the subsequent car wash. The TUGA product range is coordinated — biodegradable according to German detergent law, produced in Osnabrück.\u003c\/p\u003e\n\n\u003cp\u003eHowever, the biggest practical advantage of the gel cleaner is over liquid alternatives: While liquid rim cleaners run off vertical spokes within seconds and achieve only a fraction of the exposure time, the gel stays where you spray it — and works for the full 3–5 minutes. This difference is particularly noticeable with multi-part rims with many spoke gaps. There, liquid cleaners run off immediately. The gel stays, reacts, discolors — and you see exactly when the brake dust is dissolved.\u003c\/p\u003e\n\n\u003c!-- 📸 FOTO 4: LINEUP-BILD — 1L und 5L nebeneinander\n     Alt-Text: \"Alu-Teufel Spezial Grün alle Gebindegrößen 1 Liter und 5 Liter\" --\u003e","brand":"TUGA Chemie","offers":[{"title":"1000 ml \/ 1 liter","offer_id":56936419098959,"sku":"D1-TGC-AS1D","price":13.21,"currency_code":"EUR","in_stock":true},{"title":"5 liters","offer_id":56936419131727,"sku":"D1-TGC-AS5D","price":44.73,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/tuga-chemie-alu-teufel-spezial-gruen-felgenreiniger.png?v=1770230457","url":"https:\/\/detailing1.nl\/en\/products\/tuga-chemie-alu-teufel-spezial-gruen-felgenreiniger","provider":"Detailing1","version":"1.0","type":"link"}
