Neoaktif Rust Buster NG 520 is an effective, highly concentrated, pH-neutral rust remover, mild to the user, material and the environment. Neoaktif Rust Buster NG 520 is optimized for CIP (Cleaning In Place) reconditioning of waterborne systems with surface rust. The product can also be used in cleaning baths. The derusting requires the presence of carbon steel in the cleaning liquid. It performs excellently when removing black rust (magnetite), red rust (hematite) and to a certain extent even other metal oxides. It has a limited effect on lime deposits.
