ABSTRACT:
Cleaning apparatus such as a degreaser tank is provided with a vapor zone divided into upper and lower portions by a wall and a closure member which cooperates with the wall so that the upper and lower portions of the vapor zone may be isolated from one another. During such isolation of the upper and lower portions of the vapor zone, vapors from the upper portion are removed to thereby facilitate introduction or removal of work pieces into the upper portion of the vapor zone while minimizing solvent losses to the atmosphere and minimizing exposure of workers to solvent vapors.
