Abstract
Improved results are obtained in the no-rub cleaning of hard surfaces when the cleaner used in the process is an aqueous solution of (A) about 40-50% by weight of a nonionic surfactant mixture of an alcohol ethoxylate and a C.sub.8-16 alkyldimethylamine oxide in a weight ratio of about 5-15/1 and (B) correspondingly, about 60-50% by weight of one or more nitrogenous builders.
