A cleaning method which comprises cleaning an object with a detergent prepared by compounding a basic detergent such as an organosilicon detergent or an isoparaffinic detergent with a detergency improver such as a surfactant or a hydrophilic solvent, rinsing the cleaned object with the basic detergent, and drying it with warm air or steam. Since the basic detergent can be recovered for reuse, the economic advantage of the use of a plurality of detergents is enhanced. Since the detergent comprises an organosilicon or isoparaffinic detergent and additives such as a surfactant or a hydrophilic solvent, it has degreasing and draining properties comparable to those of chlorofluorocarbon detergents and is harmless from the aspect of environmental pollution.
