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.
