Abstract
Process for using detergent compositions comprising a surfactant system that is either (1) a mixture of nonionic and zwitterionic detergent surfactants; (2) a mixture of nonionic and amphoteric (non-zwitterionic) detergent surfactants, preferably; or (3) short chain nonionic detergent surfactant, the nonionic detergent surfactants preferably being short chain and/or having peaked distribution; optional hydrophobic cleaning solvent; and polycarboxylate, especially dicarboxylate, detergent builder provide superior cleaning of all of the soils commonly found in the bathroom. The compositions have a pH of from about 1 to about 5.5, preferably from about 2 to about 4 when the dicarboxylate builder is used. The compositions are in the form of aqueous liquids. Short chain peaked distribution nonionic detergent suffactants provide surprisingly superior sudsing characteristics.
