The specification disloses improved compositions which both clean a surface and are believed to deposit thereupon a layer of cationic surfactant which assists the release of soil subsequently deposited upon said surface. These comprise a surfactant mixture, wherein said surfactant mixture itself comprises: a) at least 65 wt.% on total surfactant of nonionic surfactant; b) less than 1 wt.% on total surfactant of anionic surfactant; c) 0.1-35 wt.% on total surfactant of a cationic surfactant which is a mono fatty alkyl quaternary ammonium compound wherein the alkyl chains comprise at least 10 % of C18-C26 alkyl groups; wherein said composition further comprises, at least 0.5 wt.% of an organic amine having a pKa of at least 8.0. |
