A cleaning intensifier is disclosed for use in dry-cleaning machines equipped with adsorption filters, which intensifier is not adsorbed by the filters. The cleaning intensifier contains a quaternary ammonium salt in the form of difatty alkyl dimethyl ammonium chloride containing from 12 to 18 carbon atoms in the alkyl radical or a mixture of the homologues, and the triammonium salt of a tricarboxylic acid citric acid or tricarballylic acid, and a tertiary amine in the form of a fatty alkyl dimethylamine containing from 8 to 18 carbon atoms in the alkyl radical or a hydroxy ethyl amine derivative corresponding to the formula <IMAGE> where R is a fatty alkyl radical containing from 10 to 18 carbon atoms, or a mixture of these triammonium salts. Preferred embodiments include content of nonyl phenyl ethoxylate containing from 5 to 11 moles of ethylene oxide or a fatty alcohol ethoxylate containing from 10 to 18 carbon atoms in the alcohol component and 3 to 9 moles of ethylene oxide or a mixture of these ethoxylates as the non-ionic surfactant; and content of a C2-C8-alkylene glycol as the alcohol.
