Abstract
Compositions described herein are aqueous detergent compositions, preferably hard surface cleaning compositions, which contain alkyl aryl sulfonate surfactant, selected hydrophobic cleaning solvent, polycarboxylic acid, and aqueous solvent system in solution and/or a micellar phase, the pH being from about 2 to about 4. The have excellent soap scum removal and hard water deposit removal properties and are easy to rinse. Such compositions optionally contain additional anionic sulfate surfactant, cationic surfactant, peroxide and/or hydrophilic polymer for additional benefits.
