Koch Chemie Reactive Rust Remover (RRR) is a professional pH-neutral iron and fallout remover that dissolves rust, embedded iron particles, metallic contamination, and brake dust from paint, clear coat, wheels, and glass surfaces. The reactive formula turns violet on contact as it chemically reacts with iron particles, breaking down non-organic contamination for thorough, easy rinsing without scrubbing. The color change also gives you a clear visual indicator of contamination levels across different areas of the vehicle.

pH-neutral chemistry makes it safe on all vehicle surfaces including sensitive clear coats, chrome, polished aluminum, and glass. A critical step before paint correction or ceramic coating application to ensure the surface is truly clean and free from bonded metallic contamination that would otherwise interfere with polishing or coating adhesion.

If you are looking for the best iron and fallout remover for professional detailing, a Koch Chemie rust remover that is safe on paint and all exterior surfaces, or a color-changing decontamination spray for removing brake dust and metallic fallout before polishing or coating, RRR Reactive Rust Remover is a benchmark decontamination product from one of the most trusted names in professional detailing chemistry. Available in 500ml and 5L.
