ABSTRACT:
A cleaning composition for removing kinetically inert high oxidation state metal coordination complex stains, lime scale, soap scum, soil, grease, and biofilm deposits from ceramic surfaces, such as porcelain and glass, and other hard surfaces. The composition includes an acid component; a reducing component; a surfactant system component; and a complexing system component. In one aspect, the cleaning composition includes sulfamic acid, in an amount between about 20 and about 80 weight percent of the composition; isoascorbic acid, in an amount between about 0.1 and about 20 weight percent of the composition, for reducing kinetically inert high oxidation state metal coordination complex stains; a non-interfering surfactant system; and a complexing system comprising ethylenediaminetetraacetic acid and citric acid, the ethylenediaminetetraacetic acid comprising between about 0.01 and about 10 weight percent of the composition, and the citric acid comprising between about 5 and about 45 weight percent of the composition. In another aspect, the invention also relates to methods for cleaning and removing complex stains from surfaces.
