PROBLEM TO BE SOLVED: To provide a novel solvent composition which has excellent detergency and can be used in a wide range of cleaning uses. SOLUTION: A solvent composition comprises 10 to less than 35 wt.% dichloropentafluoropropane and more than 65 to 90 wt.% CF3-[O-CF (CF3)- CF2]n-(O-CF2)m-O-CF3 (wherein m is an integer of 0-6; and n is an integer of 0-6, provided that m=n=0 is excluded). The dichloropentafluoropropane is preferably 3, 3-dichloro-1,1,1,2,2-pentafluoropropane and/or 1,3-dichloro-1,1,2,2,3- penta-fluoropropane.
