Abstract:
An aqueous, hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising:(a) no more than about 50% of at least one organic solvent with a vapor pressure of at least 0.001 mm Hg at 25Â° C., and mixtures of such solvents; (b) about 0.001-10% of a mixture of anionic surfactants, which comprise C6-20 alkyl diphenyloxide disulfonate and either C6-20 alkane sulfonate or C6-20 alkyl sulfonate, or a mixture of all three, the alkyl diphenyloxide disulfonate providing a distinct auditory signal when a glossy hard surface is cleaned with said hard surface cleaner; (c) about 0.01-2% of a buffering system which comprises a nitrogenous buffer which will result in a pH of greater than 6.5; and (d) the remainder as substantially all water.
