Machine dishwashing compositions comprising quaternary ammonium salts of formula: ##STR1## wherein from one to three members of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent alkyl chains which may be the same or different, at least one of said alkyl groups representing a C.sub.8 -C.sub.26 group, those members of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 which do not represent alkyl groups representing ethoxy groups, the total ethoxylation value within the molecule being at least 5 and X.sup.- representing an anion, enable washing to be carried out efficiently at lower temperatures. Fat removal is enhanced.
