SLIPKOTE® DISC ROTOR CLEANER is a water-based cleaner with no VOC’s that cleans and protects against corrosion. SLIPKOTE DISC ROTOR CLEANER combines the state-of-the-art cleaner surfactants, with ferrous and non-ferrous metal (i.e. copper) corrosion inhibitors in a stable aqueous solution. This combination cleans disk brake rotors quickly, restoring the rotor to near new condition. SLIPKOTE® DISC ROTOR CLEANER leaves behind a thin corrosion-protection coating, which greatly prolongs rotor life.
