CitriSurf 2210 is a high quality blend of chemicals formulated for the cleaning and passivation of stainless steel products. It is provided in a high viscosity form for easy application on weld joints, vertical surfaces, and other large items or areas that cannot be conveniently dipped in a bath. CitriSurf 2210 is specifically designed to provide low cost and efficient removal of all free iron from the surface of stainless steel and other metals, providing the highest chrome oxide levels possible.

To assure best results, the parts to be treated should be thoroughly cleaned to remove dirt, oils, and grease with an appropriate cleaning solution prior to treatment with CitriSurf 2210, although it is a very good cleaner by itself if used properly. If thorough cleaning is not possible during use in the field, wipe the surface free of dirt and oils prior to application.
All equipment, mixers, applicators or pumps should be clean and dry prior to use. Only containers constructed of polypropylene, polyethylene, or other acid resistant plastic or stainless steel should be used to hold or store this product.
Depending on the product being cleaned, passivated, or brightened, dilution of the CitriSurf 2210 with water at a maximum 1 to 1 ratio by volume may be advantageous or necessary to slow down the reaction rate or lower the viscosity. Time, temperature and concentration of the product should be tested prior to use in production. For more aggressive cleaning, longer times, higher temperatures and higher concentrations are advantageous. Please contact the manufacturer for assistance if necessary to determine the best formula and conditions for your product. Each application is different!
Prior to use, mix thoroughly by shaking or stirring. CitriSurf 2210 should be applied liberally to the surface to be treated with a sprayer, brush or roller. Coverage is approximately 250 square feet per gallon. Wait approximately 10 to 30 minutes, depending on the application, and then rinse the product from the surface completely. Repeat process if needed to obtain desired results.
Note: CitriSurf 2210 must remain moist during the treatment period. When using CitriSurf 2210 in direct sunlight or other hot environments, it may be necessary to periodically sprinkle the surface lightly with water to keep the CitriSurf from drying.
Rinse thoroughly with clean water and dry completely in air immediately or proceed with post-treatment to obtain the desired results. Drying can be accelerated by use of a hot air oven or other drying medium such as an air blower (hair dryer) to attain a clean, dry surface prior to post treatment or packaging.
Although very safe in normal use, CitriSurf 2210 is a Citric Acid based material, and as such it may cause irritation to exposed
surfaces of the body. See Material Safety Data Sheet before using this material. Rubber or plastic gloves should be worn
to apply the product to the surface or to wipe it dry.
Do not apply CitriSurf 2210 to electrical wiring or other conductive material that is connected to electrical current
without first turning off all electricity! CitriSurf is a water based conductive material. Serious injury or death con occur from
electrical shock.
Do not leave concrete or carbon steel exposed to CitriSurf for any period of time. Damage to these materials will occur
with prolonged exposure.
Dispose of according to all federal, state and local regulations.
CitriSurf 2210 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.)

CitriSurf 2210 meets all of the requirements of ASTM A-967 and AMS 2700 specifications.
Testing of your products with CitriSurf before using in production is recommended. Every product and production facility is different, and requires testing to ensure that CitriSurf is compatible with the particular situation.
