Product Dose

The parts or areas to be cleaned and passivated should be sprayed, immersed or wiped with ORG CITRISURF 77 to completely wet the surfaces, especially in crevices or in areas where any rust or corrosion may have occurred. The surface must be soaked or left moist with the ORG CITRISURF 77 solution for a period sufficient to remove all corrosion, free iron and contaminants from the surface. This is typically 15-30 minutes at room temperature, depending on the grade of stainless steel, hardness, and the condition of the surface. This should be determined by testing with your product. Coverage is approximately 90 square feet per 22 oz. bottle. If heavy rust needs to be removed, Scotch Brite (TM) or other non iron containing abrasive may be helpful. Difficult rust or corrosion must be tested to determine the exact best conditions for removal.

Rinse thoroughly with clean water and dry completely in air immediately. Drying can be accelerated by use of a hot air blower (i.e. hair dryer), clean cloth, or other drying medium to attain a highly passive surface. Repeat process if needed to obtain desired results.
