Abstract: A method for cleaning objects is disclosed. The method includes placing the objects into a cleaning chamber and contacting them with a dense phase gas. After draining the dense phase gas from the cleaning chamber, the pressure in the cleaning chamber is changed at a rate of at least 1 bar per minute, preferably at a rate of 5 bar per minute, more preferably at a rate of 10 bar per minute.

Abstract: The invention relates to a method for cleaning objects in a cleaning vessel using liquid carbon dioxide, wherein the cleaning vessel is at least partly filled with liquid carbon dioxide. Prior to and/or during the cleaning operation the pressure within said cleaning vessel is raised to a value above the corresponding vapour pressure. A gas other than carbon dioxide is introduced into said cleaning vessel and at least a portion of the cleaning operation is performed after the introduction of said gas.
