1. An aqueous liquid hard surface detergent composition comprising:
- (a) amphoteric detergent surfactant;
(b) specific anionic surfactant herein having the generic formula;
space="preserve" listing-type="equation">R'"'"'(C.sub.6 H.sub.3 SO.sub.3.sup.-)--O--(C.sub.6 H.sub.3 SO.sub.3.sup.-)R'"'"'(nM).sup.++wherein each R'"'"' is an alkyl, or alkylene, group containing from about 6 to about 12 carbon atoms, and M is a compatible cation, with n being selected to provide electrical neutrality;
(c) cleaning solvent having a solubility in water of less than about 20%; and
(d) the balance being an aqueous solvent system, the composition being unstable, due to the presence of (c), in the absence of (b), and the level of (b) being sufficient to maintain the stability of the composition.

Abstract
The present invention relates to an aqueous, liquid, hard surface cleaning compositions containing amphoteric/zwitterionic detergent surfactant, specific anionic surfactant, cleaning solvent, optional nonionic detergent surfactant, and buffer. The buffers can be either alkaline or acid for improved cleaning of acid sensitive soils like soap scum and/or hard water deposits. The presence of the specific anionic surfactant permits the inclusion of more of relatively hydrophobic materials like cleaning solvents, which provide improved cleaning, especially under acid conditions where some greasy/oily soils are more difficult to remove.
