摘要
A contaminated article is subjected to vapor degreasing operations wherein the vapor degreasing solvent is a blend consisting essentially of methylene chloride and either 1,1,1-trichloroethane or trichloroethylene. Addition of methylene chloride to the solvent blend is found to stabilize the other component of the blend in the presence of contaminants encountered in the conventional vapor degreasing process; thus extending the normal life of the degreasing solvents.
