Rust Cleaner

Mildly alkaline cleaning agent for removing rust stains and other metal oxide residues. The reactive substances act on rust and convert them into water-soluble substances. The beginning of the reaction can be seen by the violet colouration. The by-products from the reaction can be rinsed off with water. Sidec Rust Cleaner can be applied specifically to partial surfaces, as no visible changes to the surface occur.


For removing rust stains of all kinds.
For use indoors and outdoors.
