SSC 500/50 is a powerful oxidizing, heavy duty acid based cleaner for corrosion and stain removal caused by oxidation of stainless steel 304 and 316. It can be used to retard the re-dulling of the cleaned surface. SSC 500/50 is ideal for exterior cleaning of tanks and equipment too large for immersion. SSC 500/50 has been designed to remove ferrous stains and iron particles, industrial or atmospheric fallout, fingerprints and oils which dull the surface, hard water scale particularly cooling water stains and algae growth. The clean stainless surface allows for self-passivation properties to continue.
