A few hundred miles of hard braking and the iron particles have bonded to the lacquer, and a normal shampoo wash slides straight over them. Felgenblitz is Koch Chemie's acid-free rim cleaner for exactly that job: a viscous gel that clings to the wheel, turns red as it dissolves the iron, and rinses off without attacking the finish.\u003c\/p\u003e\u003ch3\u003eWhy it works\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAcid-free, pH-neutral chemistry cleans burnt-in brake dust without etching alloy, steel or chrome\u003c\/li\u003e\n\u003cli\u003eViscous gel clings to vertical spokes and barrels instead of running straight off\u003c\/li\u003e\n\u003cli\u003eColour indicator turns red as it reacts with iron contamination, so you can see where it's working\u003c\/li\u003e\n\u003cli\u003eKoch Chemie specify around 3 minutes of dwell before you touch a brush\u003c\/li\u003e\n\u003cli\u003eWater-repelling and gloss-enhancing additives leave the rim easier to clean next time\u003c\/li\u003e\n\u003cli\u003e5L and 10L trade packs refill a trigger bottle for a fraction of the per-litre price\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhen to use it\u003c\/h3\u003e\u003cp\u003eOn wheels that haven't been deep-cleaned in months — winter brake dust, motorway film, rust traces around the wheel nuts.
