Abstract
Abrasive, hard surface cleanser compositions containing a surfactant, a particular type of expanded perlite material and a filler material which can be inorganic salt, water or mixtures thereof. Such compositions, whether liquid or granular, provide excellent stain and soil removal from hard surfaces but leave very little or no residual abrasive grit after being rinsed from such surfaces.
