This invention provides a new approach to the dry-cleaning of garments and fabrics by using ultra-sonic energy as to the cleaning force. The garment first enters a pair of air compartments which prepare the garment for the wash tank. In the wash tank, which is filled with a liquid solvent, transducers in the wall of the tank apply ultra-sonic energy to the garment to clean it. Upon emergence from the tank, the garment again passes through compartments which first dry the garment and then cool it.
