ABSTRACT:
Heavily soiled fabrics are pretreated before the actual washing process by applying a paste containing a mixture of a nonionic surfactant, at least one nitrogen containing compound selected from certain quaternary ammonium compounds, fatty amine ethoxylates and substituted aminocarboxylic acids, and also an antigel agent and a viscosity regulator to the fabrics and subsequently washing the fabrics in a wash liquor. In one preferred embodiment of the process, a distributing aid trimmed in particular with bristles is used to apply the paste.
