The system comprises a cleaning fluid circuit including at least one sealable cleaning vessel, which is adapted to hold a vacuum and contains a carrier for carrying stock to be cleaned and dried. The cleaning vessel is adapted to be hermetically sealed from the atmosphere and from the cleaning fluid circuit is adapted to be directly connected to the suction port of an ejector so that each batch of stock can be cleaned and can subsequently be dried more quicly and to a higher degree by the application of a desired vacuum. Even if the cleaning fluid consists of an organic solvent, the pollution of the premises and of the environment by solvent vapors will be minimized.
