Abstract: A method for cleaning objects in a pressure vessel with liquefied gases is provided. The gas liquefied under pressure is conducted into the pressure vessel. The temperature of the liquefied gas then, or beforehand, is lowered below the critical temperature of the gas and cleaning is performed at least primarily below the critical temperature and below the critical pressure of the gas. Carbon dioxide at temperatures between -20.degree. C. and +20.degree. C. is especially suitable. The mechanical interactions produced by the increased density and viscosity of the liquefied gas reinforce cleaning. Reduced solvent capacity does not influence the effectiveness of the cleaning. Textiles or components can therefore be cleaned at lower pressure and temperature.
