<p>Aqueous acidic, abrasive hard surface cleaning composition comprising: about 0.5 - 3.5 %wt. of a thickener system which includes both a colloid forming clay, preferably a montmorillonite clay, and a gum based thickener, preferably xantham gum; about 0.01 - 2.5 %wt. of a surfactant selected from anionic surfactants, nonionic surfactants, and mixtures thereof; an antimicrobially effective amount of at least one organic acid present in an amount of from about 2 - 12 %wt.; as an abrasive constituent, pumice, which may be present in an amount of at least about 5 %wt.; optionally but preferably an opacifying/tinting constituent; 0 - 5 %wt. of one or more optional constituents for improving the aesthetic characteristics of the compositions; and, at least 75 %wt. of water; wherein the compositions exhibit a viscosity of between about 250 cps to about 1000 cps at 25 °C, and, exhibit an acidic pH of less than about 5. The compositions are particularly useful in the cleaning treatment of hard surfaces, particularly lavatory surfaces.</p> |
