Abstract (en)
In a method for dry cleaning with a petroleum solvent, the inside of a washing bath in which at least fabrics to be cleaned are placed is depressurized to a predetermined value, and thereafter an inert gas is introduced into the washing bath until the oxygen density of the mixture containing the solvent gas takes a value below a predetermined one, namely, a peak value of the inflammable range, thereby eliminating the danger of solvent gas explosion and shortening the time for drying of the fabrics, these steps being done before the step of drying the fabrics.
