Abstract
The parts are heated by conduction and radiation while the chamber is evacuated, whereupon the chamber is sealed air-tight and the parts are also heated by condensation of vapors from the grease and oil. When the parts reach a constant temperature the chamber is again evacuated, causing the temperature of the parts to drop as condensate thereon evaporates. Finally, the chamber is returned to atmospheric pressure and the cleaned parts are removed.
