ABSTRACT:
Improved cleaning compositions are disclosed based on fluorochlorohydrocarbons, alkanols and at least one ester selected from the group consisting of methyl propionate, ethyl propionate and ethyl acetate. The compositions may optionally contain additional additives and are highly suitable for industrial cleaning processes or for vapor degreasing, for example, particularly for removing resin soldering fluxes containing high amounts of activator.
