ABSTRACT:
A hard-water-deposit-removing composition comprises the hydrochloride salt of a 2-aminocarboxylic acid, water, optionally a thickener, optionally an abrasive, and optionally a surfactant. The invention further provides a method for removing hard-water deposits from metal, glass, plastic, and ceramic surfaces by applying the composition, allowing contact until substantially all of the deposit is removed, and washing away the composition and dissolved deposit with water.
