Abstract

Aqueous, liquid hard surface detergent compositions having improved cleaning and good filming/streaking characteristics contain specific polycarboxylate detergent builders at critical levels. Preferred formulas contain a zwitterionic/anionic detergent surfactant mixture at levels (e.g., from about 0.02 to about 15%); hydrophobic solvent; alkaline material, especially volatile alkaline materials comprising monoethanolamine or certain beta-amino-alkanol compounds; and salt of ethylenediaminetetraacetic acid as the detergent builder in levels (e.g., from about 0.05% to about 0.5%, by weight of the composition).
