Abstract

A heavy duty process for laundering greasy stains from a fabric which comprises treating the fabric with an aqueous detergent composition comprising (a) 0.5 - 5 % by weight of a nonionic surfactant and (b) 1 - 10 % by weight of an apolar solvent in a ratio from less than 1 : 1 to 1 : 10. Preferably, the hot wash liquor is treated in a filtering step using microfilters to separate the organic solvent phase from the aqueous phase, which is then recycled.
