Abstract

PROBLEM TO BE SOLVED: To enhance safety, to retard rusting after cleaning and to improve cleaning effect retentivity by removing rust from a metal with a cleaner comprising an aq. soln. of an amino acid or its deriv. SOLUTION: An amino acid or its deriv. is mixed with water, agitated and dissolved to prepare the objective metal cleaner. The amino acid is preferably arginine, alanine, glycine, glutamic acid, serine or a mixture of arginine and other amino acid preferably in a ratio of (3:1) to (1:1). A metal is immersed in the aq. soln. to remove the rust and then the metal is washed and dehydrated. The metal taken out of the aq. soln. is generally freed of the rust by soft wiping with cloth, washed and dehydrated with dry cloth.
