FeDOX Rust Remover (Concentrated) is specially developed for de-rusting of steel parts and inner tank surfaces. It can be diluted in water, with a maximum dilution ratio of 1:10. The parts to be derusted are then immersed in the solution. The solution can be heated up to 65°C for faster derusting. The duration of derusting varies depending on the thickness of the parts. Flash rust is removed within 15-45 minutes while a thicker layer of rust takes up to 12-24 hours of time. Post de-rusting the components should be washed with water and coated thereafter immediately with any kind of waxes or primers. Can be used for derusting of: Tools and metal parts Casings Turbines and machine parts Interior surface of a tank, et. al.
