A method for cleaning cavities in workpieces, a cleaning device for this purpose and a device for the supply of media to a cleaning device of this type.

The supercritical carbon dioxide located in the cavity is relieved of pressure after rinsing of the cavity, so that carbon dioxide gas and carbon dioxide snow are formed in the cavity and subsequently driven out of the cavity.
