An acid-free, viscous wheel cleaner from Koch-Chemie's workshop line, which visibly and chemically dissolves brake dust and rust film via a red-violet color change. Suitable for painted aluminum, polished aluminum, chrome, and steel. Not suitable for baked-on tar or bitumen stains.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003cp id=\"speakable-definition\"\u003e\u003cstrong\u003eKoch-Chemie Magic Wheel Cleaner\u003c\/strong\u003e — often called \"MWC\" internally — is an acid-free wheel cleaner from Koch-Chemie's workshop line. The active ingredient, ammonium mercaptoacetate, a salt of thioglycolic acid, reacts with iron(III) compounds in brake dust and dissolves them as a red-violet complex from the rim surface. The color change is not a marketing gimmick but rather a direct chemical reaction: where you see violet, iron is being converted. With a pH value of 5–6, the formulation remains gentle on painted and polished aluminum rims, chrome, and steel. The high viscosity of 50 mPa·s ensures that the product adheres to vertical rim surfaces instead of running off immediately — thus maintaining the full dwell time on the material.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRed-violet color change as a reaction indicator.\u003c\/strong\u003e No guessing how long you have to wait. You see in real time where iron particles react and when the reaction is complete. This prevents two classic mistakes: rinsing too early (incomplete cleaning) and letting it sit for too long (product becomes saturated and dries on).\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSyrup-like viscosity for vertical adhesion.\u003c\/strong\u003e With 50 mPa·s, Magic Wheel Cleaner is thick enough to stay in spokes and on the rim flange without immediately dripping to the ground. This distinguishes it from watery wheel cleaners, where half of the product would run off unused.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOne cleaner for the entire wheel inventory.\u003c\/strong\u003e Painted aluminum, polished aluminum, chrome, and steel — the pH of 5–6 is mild enough to be used even on high-gloss polished forged rims. For anodized or matte-coated rims, test in an inconspicuous area first.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1 Pro Tip:\u003c\/strong\u003e Always spray onto a cold, dry rim — never in direct sunlight, never on warm brakes after driving. Warm surfaces cause the gel to dry, leaving residues that you then have to remove with a brush. For heavily soiled rims after months without cleaning, two short applications work better than one long one: the active ingredient is chemically saturated after about 5 minutes. Simply let it sit for 3 minutes twice, rinsing in between.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eCold rim. Spray. Wait 2 to 5 minutes.\u003c\/h3\u003e\n\u003cp\u003eSpray the Magic Wheel Cleaner onto the cold, dry rim — evenly covering spokes, rim bed, rim flange, and wheel bolts. Due to its syrupy consistency, the product adheres vertically, without requiring you to change your handling. It's best to work from bottom to top so you don't overlap already wetted areas.\u003c\/p\u003e\n\n\u003cp\u003eAfter 30 to 60 seconds, the color change begins: first in areas with a lot of brake dust, then over the entire surface. Red-violet streaks show you exactly where iron particles are being converted and after 2 to 5 minutes of dwell time, the reaction is complete — waiting longer is pointless because the active ingredient is saturated after about 5 minutes. A common mistake is to leave the product on for 10 minutes hoping for a better effect. The opposite happens: the solution starts to dry and leaves streaks.\u003c\/p\u003e\n\n\u003cp\u003eFinally, rinse off with a strong jet of water from a pressure washer or garden hose, working from top to bottom. For heavy brake dust between narrow spokes, a \u003ca href=\"\/en\/collections\/zubehoer-felgenpflege\"\u003ewheel brush\u003c\/a\u003e can help distribute the dissolved material — but not for scrubbing, only for finishing. If you clean weekly to bi-weekly, one pass is usually sufficient.\u003c\/p\u003e\n\n\u003cp\u003eA note on dosage: 500 ml is enough for about 10 complete vehicle cleanings. 40 to 50 ml per wheel is sufficient. That's 1.25 Euros per complete application — significantly more economical than the bottle price suggests, if you factor in the time spent scrubbing with less effective cleaners.\u003c\/p\u003e\n\n\u003ch3\u003eIt dissolves iron particles. Not tar.\u003c\/h3\u003e\n\u003cp\u003eMagic Wheel Cleaner is precisely designed for one task: to chemically dissolve brake dust and rust film. The reaction between ammonium mercaptoacetate and iron(III) ions in brake dust is the active mechanism — anything that is not iron is not affected. This explains the color change as a diagnostic tool: no discoloration means no iron, and no effect in that case is not a product defect, but the correct response to the dirt.\u003c\/p\u003e\n\n\u003cp\u003eAs a secondary application, Magic Wheel Cleaner also works on paint as a rust film remover — particularly interesting for vehicles parked under industrial exhaust or next to railway tracks. Fine iron particles settle on the clear coat there and react with the MWC formulation just as they do on the rim. Used before polishing, it increases the adhesion of subsequent wax or ceramic sealants because the paint surface is truly contamination-free.\u003c\/p\u003e\n\n\u003cp\u003eWhere MWC is not the right product: Baked-on tar, bitumen stains, and oily contaminants do not react with thioglycolate salts. For these, you need a solvent-based tar remover. For extremely neglected rims 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 might be the better choice — its acid system is more powerful, but not suitable for all rim materials. The decision is clear: If safety on chrome and polished rims matters, use MWC. If maximum cleaning power is needed and you're working with painted aluminum and steel, use RWC.\u003c\/p\u003e\n\n\u003cp\u003eA second case where no wheel cleaner in the world will help: if the rim is already visibly corroded or the clear coat has flaked off. At that point, cleaning is no longer the issue, but paint refurbishment. Magic Wheel Cleaner is a care product — not a restoration agent.\u003c\/p\u003e\n\n\u003ch3\u003eYour standard for regular wheel workflow\u003c\/h3\u003e\n\u003cp\u003eMagic Wheel Cleaner is the right choice for anyone who maintains their rims on a regular basis and is looking for a product where they don't have to worry about material compatibility. One product, one work step, all wheels done. That's workshop logic — and that's exactly what MWC is formulated for.\u003c\/p\u003e\n\n\u003cp\u003eIt particularly shines when you maintain several vehicles with different rim types or work in a fleet. Instead of three cleaners for three rim types, one is enough. It is less effective for extremely baked-on brake dust residues from high-performance braking systems or for rims that haven't been cleaned for months. In both cases, a second application or a more aggressive product is more sensible than extending the dwell time.\u003c\/p\u003e\n\n\u003cp\u003eAs a complete solution, Magic Wheel Cleaner works best in combination with a \u003ca href=\"\/en\/collections\/vorreinigung\"\u003epre-cleaner\u003c\/a\u003e like Koch-Chemie Pre-cleaner B, which is applied as a foam to the entire rim before MWC goes into the spokes. Finish with a \u003ca href=\"\/en\/collections\/reifenpflege\"\u003etire dressing\u003c\/a\u003e on the sidewall — and the complete wheel workflow takes about 15 minutes per vehicle if you keep up with it every two weeks. This is our customers' most common purchase combination: Pre-cleaner B + Magic Wheel Cleaner. A precise, repeatable process that works without scrubbing.\u003c\/p\u003e\n\n\u003cp\u003eIn direct comparison with the acid-free classic SONAX FelgenBeast, Magic Wheel Cleaner is superior in two respects: the higher viscosity ensures longer contact time on the rim, and the workshop formula is more concentrated for commercial use. However, FelgenBeast has a milder odor — something you might notice if you work in a closed garage. Magic Wheel Cleaner is the workshop standard. FelgenBeast is the garage all-rounder. Both do their job reliably; the question is which one suits your work environment.\u003c\/p\u003e","brand":"Koch-Chemie","offers":[{"title":"500ml","offer_id":48503670374735,"sku":"D1-KCX-425500","price":55.74,"currency_code":"PLN","in_stock":true},{"title":"2x 500ml","offer_id":49725159276879,"sku":"D1-KCX-425500_2","price":109.23,"currency_code":"PLN","in_stock":true},{"title":"3x 500ml","offer_id":49725159342415,"sku":"D1-KCX-425500_3","price":162.25,"currency_code":"PLN","in_stock":true},{"title":"10 liters","offer_id":48503670407503,"sku":"D1-KCX-68809","price":544.9,"currency_code":"PLN","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","url":"https:\/\/detailing1.pl\/en\/products\/koch-chemie-magic-wheel-cleaner-mwc-felgenreiniger","provider":"Detailing1","version":"1.0","type":"link"}
