As the cleaning device, a general vapor cleaning device 2 shown in FIG. 1 is used, which is usually freon or 1.1.1-trichloroethane. The object to be cleaned 3 to which cutting powder and cutting oil had adhered was put into steam for cleaning. as a result,

This is because if the content exceeds 5% by weight, the completely fluorinated fluorocarbon-based inert liquid and the hydrocarbon-based solvent are completely separated into two layers, which may cause ignition.

As a result, oil and cutting powder were washed away, and the cleaning liquid 1 remaining on the surface of the pressing mold was also evaporated, and a cleaning effect equivalent to that of CFC and 1.1.1-trichloroethane was obtained.

Further, if only a hydrocarbon solvent is used, there is no problem in cleaning quality, but there is a risk of fire.
