Abstract
Abstract Aqueous, liquid hard surface detergent compositions having good filming/streaking characteristics contain short chain amphocarboxylate detergent surfactant; hydrophobic, volatile cleaning solvent; and, optionally, zwitterionic detergent surfactant and/or monoethanolamine and/or other specific beta-aminoalkanols for improved filming/streaking and good cleaning. Preferred formulas do not contain large amounts of builders and/or other materials that contribute to bad spotting and filming and said formulas are suitable for general purpose cleaning including cleaning of glass.
