This powerful, pH-neutral cleaner is made with reactive agents and extra high performance detergents. Superficial rust, metal particles, burnt-in brake dust and other non-organic pollutants are swiftly and thoroughly cleaned away. Gentle for materials. Components are harmonised for a longer contact time / moisturisation, so that the reactive agents can dissolve tough stains and burnt-in particles effectively. The cleaner, once it has dissolved the dirt, turns violet in colour. The special surfactants in the formula coat and disperse the partially dissolved dirt, so it is easy to rinse it off.
From ImJoshV: This is my favorite Iron Removing product. I personally don't love using Iron Removers because they have a pretty strong and unpleasant smell, but they are a necessary tool in decontaminating your vehicle. Koch Chemie Reactive Rust Remover is my favorite because it just works so well! It seems to work much faster than others i have used and stays lubricated longer! These features really help me as a mobile detailer that doesn't always have the luxury of working in the most ideal environments.
