Pickling and Passivation
Pickling: Complete removal of oxides, carbon, scale and other impurities from stainless steel.
Passivation: Regeneration of the protective surface to resist corrosion.
Derustit SS-3 Stainless Steel Cleaner - in liquid and paste form - is a carefully balanced formulation of effective pickling agents combined with special inhibitors.
