PURPOSE: To obtain a cleaning solvent for dry cleaning, comprising a specific organic solvent as an active component and holding excellent characteristics in place of a fluorocarbon R113 destroying the ozonosphere.

CONSTITUTION: The objective cleaning solvent for dry cleaning is obtained as a substitute for 1,1,2-trichloro-1,2,2-trifluoroethane (hereinafter referred to as R113) by including ≥50wt.% 1H,1H,5H-perfluoropentane as an active component. This detergent holds excellent characteristics possessed by the R113 and is useful as a substitute for the R113 having the high ability to destroy the ozonosphere. Organic solvents are selected from 5-15C hydrocarbons, alcohols, ketones, esters, chlorinated hydrocarbons, etc., as a preferred organic solvent to be included in combination.
