CitriSurf® 77 Plus is a high quality blend of chemicals formulated for cleaning, rust removal, and passivation of stainless steel products. It is provided in trigger sprayer bottles for applications where it is desired to spray the product on a local area. CitriSurf 77 Plus is specifically designed to provide a portable, low cost and efficient removal of contaminants and all rust and free iron from the surface of stainless steel, providing the highest chrome oxide levels possible

Application Procedure:
CitriSurf 77 Plus is an excellent cleaner by itself for many cleaning and passivation processes. However, to assure best results, the parts or areas to be passivated may be cleaned with an appropriate cleaning solution prior to treatment with CitriSurf solution, especially when heavy grease and oils are present. If thorough cleaning is not possible during use in the field, wipe the surface free of dirt and oils prior to application. The parts or areas to be cleaned and passivated should be sprayed, immersed or wiped with CitriSurf 77 Plus 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 CitriSurf 77 Plus 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, non-abrasive Scotch BriteT or similar may be used halfway through the treatment. 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.

Notes on Use:
Increased foaming maybe observed at cooler temperatures. Heat the CitriSurf 3050 solution to minimize foaming.
Although very safe in normal use, CitriSurf 3050 is a Citric Acid based material, and as such it may cause irritation to exposed surfaces of the body. See Safety Data Sheet before using this material.
For large items where continuous spraying is not available, on-site, or spot treatment applications, ready to use versions CitriSurf 77 and CitriSurf 2210 are available.

Replenish the bath with CitriSurf and water as appropriate to compensate for drag out, evaporation, and acid consumption. The pH of the CitriSurf 3050 passivation bath should be held to within +0.1 of its initial value for normal operation. See Maintenance Sheet for further information.

Dispose of according to all federal, state and local regulations.

CitriSurf 3050 should be stored at temperatures between 50 °F and 120 °F in 316 stainless steel or approved plastic containers (polyethylene or polypropylene). (If accidentally frozen, thawing will return product to normal.)

When used correctly, CitriSurf 3050 meets the requirements of the ASTM A967, ASTM A380, ASTM B600, and AMS 2700 standards.
