Abstract

A cleaning method and cleaning system using an organic solvent such as Freon. A cleaning tank (1) is closed after an article (2) to be cleaned is placed within the cleaning tank. The cleaning tank (1) has a downwardly concave bottom wall (60) carrying ultrasonic oscillators (11). The solvent is supplied to the cleaning tank (1) from a solvent storage tank (3). The article is cleaned with the supplied solvent. After the cleaning, the solvent is discharged in liquid state from the cleaning tank (1) while vapor of the solvent which remains in the cleaning tank is discharged to a condenser (16) to condense the vapor. The condensed solvent is returned from the condenser (16) into the solvent storage tank (3). After the liquid solvent and vapor solvent are discharged from the cleaning tank (1), the cleaned article is taken out from the cleaning tank. Before the cleaned article is taken out, air is introduced into the cleaning tank (1) at least at a last part of the step of discharging the vapor of the solvent. The condenser (16) is incorporated in a distiller (14). A solvent vapor supplying unit (34) is connected to the cleaning tank (1). The thus provided closed system prevents release of Freon to the atmosphere.
