Koch Chemie (RRR) Reactive Rust Remover | Acid Free Iron Remover

Koch Chemie Reactive Rust Remover (RRR) is an acid-free, pH-neutral fallout remover that safely dissolves surface rust, brake dust and iron particles on contact.

Koch Chemie RRR is part of a modern generation of iron removers that deliver strong cleaning power without compromising surface safety. Developed for professional and enthusiast use, this iron decontamination spray tackles the kinds of bonded contaminants that washing simply can’t remove, including brake dust, light surface rust and embedded iron particles.

Formulated to cling and dwell on the surface longer than many other iron removers, RRR actively targets ferrous deposits and reacts with them to break down their structure. You’ll see the reaction as the formula shifts to a deep purple, visually confirming that it’s dissolving the fallout and drawing it out of the surface.

Unlike acidic options that can etch or stain delicate finishes, RRR maintains a pH-neutral balance of 7.5, making it suitable for paintwork, glass and wheel rims. Check sensitive surfaces such as polished aluminium on an inconspicuous area first. It’s safe for modern clear coats, coatings and even freshly detailed finishes. No dilution is required: simply spray it on, let it react, agitate if needed and rinse off thoroughly.

Whether you're prepping for polishing, coating or just doing a routine deep clean, this is a must-have in any detailing kit. It gets deep into the surface, clears the fallout and helps restore a clean base layer for whatever comes next.
