ABSTRACT:
A detergent composition which prevents tarnishing of silver and silver-plated articles comprising 1-20 weight percent of a peroxygen or hypohalite bleaching agent, 0.05 to about 10 weight percent of a 1,3-N azole compound, from 1 to 75 weight percent of a builder, and 0 to 40 weight percent of a surfactant is described, provided the pK.sub.a of the 1,3-N azole compound is lower than a pH of the aqueous solution of the composition. A method for preventing silver tarnishing of articles in an automatic dishwashing machine is also described.
