Abstract
Aqueous, liquid hard surface detergent compositions contain zwitterionic detergent surfactant and monoethanolamine and/or other specific beta-aminoalkanols as solvents and/or buffers for improved spotting/filming and good cleaning. Some formulas do not contain large amounts of builders and are suitable for general purpose cleaning including cleaning of glass.
