A low-foaming cleaning solution and dry particulate formulation which can be diluted with water, deionized water, or mixtures thereof, to form the cleaning solution. The cleaning solution has an alkaline pH, which is preferably from about 8 to about 11.5 and consists essentially of at least one low foaming surfactant in a concentration of from about 0.005% to about 40% w/w of the total solution, at least one active oxygen releasing compound in an amount effective to produce a hydrogen peroxide concentration of from about 0.005% to about 50% w/w of the total solution, at least one builder in a concentration of from about 0.001% to about 50% w/w of the total solution, and at least one diluent selected from the group consisting of water, deionized water, and mixtures thereof. The at least one surfactant is selected from the group consisting of C -C alkane sulfonates, C -C alkyl sulfates, C -C alkyl naphthalene sulfonates, polyoxyethylene/polyoxypropylene block copolymers having a polyoxypropylene molecular weight of from about 1500 to about 8500, of which less than about 30% of the total molecular weight is due to the polyoxyethylene portion, and mixtures thereof. The at least one active oxygen releasing compound is selected from the group consisting of hydrogen peroxide, at least one source of hydrogen peroxide, and mixtures thereof.
