Abstract
Abstract Improved multi-purpose metal cleaning compositions are provided comprised of 5 to 40 parts by weight ethoxylated aliphatic alcohol or ethoxylated alkylphenol, 4 to 20 parts by weight alkanolamine salt of a fatty acid, 2 to 15 parts by weight boramide, 2 to 15 parts by weight alcohol, glycol or ether glycol, 0.05 to 2.5 parts by weight antifoam agent, and 5 to 98 parts by weight water. In addition to being highly effective cleaners for the removal of grease, oil, dirt, scale and metal fines, the compositions of this invention also provide a non-sticky and non-greasy corrosion-resistant protective barrier on the surface of the metal.
