This specification applies to a mixture of sodium hydroxide and sequestering agents that when diluted with water, will remove rust and scale from iron and steel surfaces, with or without attendant paints, grease or other surface coatings. It can also be used for cleaning copper, brass magnesium and other metals, and to strip phosphate coatings where separate solutions formulated for this purpose are not available.

The diluted corrosion-removing compound is intended for immersion cleaning only (by simple immersion of the articles). The dimensional characteristics of the steel and iron articles being cleaned should not be altered by the use of the corrosion-removing compound solution.

The testing and evaluation of a product against this specification may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this specification has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any existing applicable regulatory requirements prior to its use.
