RR–2355 is used as a corrosion removing and metal conditioning compound which, when diluted with water and applied to metal surfaces, will remove rust from ferrous metal surfaces and provide a slight etching action for ferrous and nonferrous metals to promote the adhesion of paint or corrosion preventives.

RR–2355 is a non-foaming compound used as a rust remover for ferrous metal parts and as a metal conditioner for ferrous and nonferrous metal parts prior to application of paint and / or corrosion preventatives.

Since it is non-foaming it is intended for use in pressurized spray systems at temperatures up to 150^oF (66^oC) after which it is washed off with water.

RR–2355 can alternatively be used on aluminum for preparing aluminum parts for painting.

Do not use on zinc, tin and galvanized surfaces.

Add 1 of the concentrated material as received to 3 parts of water by volume. Use acid resisting steel, earthenware crocks or other suitable mixing tanks. Remove heavy rust by wire brush and heavy grease with a grease solvent before applying the compound.

After proper dilution, apply by spray, rinse with water, preferably hot; permit to dry thoroughly prior to application of rust preventive or paint.
