Reactive Rust Remover, Koch Chemie 359500

Remove embedded iron particles and stubborn brake dust safely with Koch Chemie Reactive Rust Remover. This powerful pH-neutral cleaner is formulated with reactive ingredients and high-performance detergents that effectively dissolve surface rust, metal fallout, burnt-in brake dust, and other inorganic contaminants without harming treated surfaces.

As the formula reacts with iron contamination, it turns a distinctive violet color, providing a clear visual indication that the cleaning process is working. Its advanced surfactant technology extends dwell time by keeping the surface moist, allowing the active ingredients to penetrate and loosen stubborn deposits before rinsing away effortlessly.
