These are essentially aqueous surfactant solutions of various types with or without the addition of builders and with or without the addition of water-soluble solvents or solubilizers. The consumer makes such general-purpose cleaners the requirement to be effective against all types of soiling occurring in the household. Conventional weakly alkaline or neutral all-purpose cleaners largely meet this requirement with regard to oily, greasy and dusty soiling.
