ABSTRACT:
In a dry cleaner, after clothes 2 is washed, the washing solvent contained in the washed clothes 2 is dissolved into a liquid perfluorocarbon 4a being heated at its boiling point or thereabout in order to remove the washing solvent. Thereafter, drying of the clothes 2 is performed by mainly aiming to evaporate the liquid perfluorocarbon 4a contained in the clothes 2. Since the drying is targeted on the liquid perfluorocarbon, the time required for drying clothes can markedly reduced.
