1. A stabilized acidic bleaching composition comprising an admixture of:
- (a) a bleaching source of unipositive chlorine ion;
(b) a chlorine stabilizing agent selected from the group consisting of sulfamic acid, alkyl sulfamates, cycloalkyl sulfamates, aryl sulfamates and melamine;
(c) an acidic buffer present in an amount effective to provide said bleaching composition with a pH in a range of about 2 to about 6.5, wherein said acidic buffer comprises a weak acid and a salt of said weak acid; and
(d) water;
wherein the molar ratio of chlorine stabilizing agent to the unipositive chlorine ion in the composition is greater than about 1;

Abstract
The composition of this invention is a stabilized acidic bleaching composition comprising an aqueous solution of a source of source of unipositive chlorine ion, a chlorine stabilizing agent, and an acidic buffer to stabilize the pH of the bleaching composition in the range from about 2 to 6.5, wherein the chlorine stabilizing agent and the source of source of unipositive chlorine ion are in a molar ratio of greater than about 1:1. Methods are described for removal of lime scale from a hard surface controlling microbial activity as well as reducing malodor by applying the composition of this invention.
