Abstract : The patent describes a nonaqueous liquid surface-active composition for displacing liquid organic films from solid surfaces. The composition is a solution of a silicone solute in a pair of volatile co-solvents in which the solute and one of the co-solvents are active displacing agents. The solute may be a low molecular weight dimethyl silicone, a liquid linear polyoxyalkylated dimethyl silicone or a fluorosilicone. The co-solvent which is an active displacing agent is a volatile liquid perfluoroalkane or fully fluorinated bromo- or chloroalkane. The other co-solvent is an aliphatic naphtha.
