Q. Surface contamination interferes with formation of protective oxide coating on stainless steel thereby leaving it open to corrosion.

The stainless steel needs passivation. Can Alconox, Inc. help?

A. Stainless steels are autopassivating in the sense that the protective oxide passive film is formed spontaneously on exposure to air or moisture.

Surface contamination, may interfere with the formation of the passive film. The cleaning of these contaminants from the stainless steel surface with citric acid detergent will facilitate passivation by allowing the oxygen access to the surface.

Passivate by immersing the stainless steel in either a 30% solution (300mL/L) of Citranox® Liquid Acid Cleaner and Detergent or Citrajet® Low-Foam Liquid Acid Cleaner/Rinse at any of the following combination of
