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.

Stabilized acidic chlorine bleach composition and method of use

An acidic bleaching solution formed from the admixture of a first aqueous solution containing a chlorine deactivating agent and a second aqueous solution containing a hypochlorite salt is disclosed. Also disclosed is a bleaching system for forming the acidic bleaching solution, as well as a method of preparing the acidic bleaching solution. The acidic bleaching solution advantageously generates little or no chlorine gas while being a particularly effective cleaner for removing soapscum, limescale, mold and mildew from treated surfaces.
