Abstract

The process relates to the cleaning of articles in a pressure vessel with liquefied or supercritical gases as cleaning fluids. For increasing the solvent capacity, it is proposed according to the invention to add chemical solvents and/or mechanical scouring means to the cleaning fluid. This accelerates the cleaning process and reduces the amount of cleaning fluid.
