An azeotropic solvent composition comprising a dichloropentafluoropropane and a fluorine alcohol. The composition is excellent in cleaning power, particularly rogin-flux cleaning power, incombustibility, chemical stability and selective solvent power, as well as has low boiling point, high solbility and easy control of the liquid composition of the solvent and easy recovering and reuse of the solvent. Especially, the composition does not corrode metals even in the presence of moisture, so, it can apply to various use conditions and various kinds of materials to be washed.
