For the purpose of cleaning parts (8), the invention comprises subjecting the latter to a prior treatment for lowering the temperature by means of a neutral gas, for example nitrogen, in an oxygen free medium, passing the parts into a cleaning chamber (4, 30) followed by subjecting the parts in succession to a partial reheating treatment in an oxygen free medium and to a treatment for drying and raising the temperature substantially to the ambient temperature. |
