ABSTRACT:
A detergent composition which prevents tarnishing of silver and silver-plated articles is described. The composition comprises 1-20 weight percent of a peroxygen or hypohalite bleaching agent, 0.05 to about 10 weight percent of a purine class compound used as a silver anti-tarnishing agent, from 1 to 75 weight percent of a builder, and 0 to 40 weight percent of a surfactant provided that the pK.sub.a of the purine class compound is below a pH of an aqueous solution of the composition in which it is incorporated. A method of using the composition is also described.
