Abrasive cleaning compositions
Abstract
Abstract This disclosure relates to abrasive cleansing compositions having particular utility as a metallic stain remover from hard surfaces such as porcelain, comprising an oxidant capable of oxidizing the metal in a practical time such as the metallic ions ferric, stannous, cupric and mercuric, a halide promotor, and an abrasive, said composition having a pH of 0.5 - 5. Additives such as detergents, perfumes, fillers, colorants, etc. may be included provided they do not adversely effect the stain removing properties of the composition. Although aluminum pot marks are most often encountered in normal household cleaning, said cleansers are effective against other metallic stains such as iron, tin, magnesium, etc.
