Rust 520

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

No transport restrictions.
