Abstract
Product cleaning apparatus having a treatment chamber provided with unheated spray cleaning zone and a sump separated by a wall and a closure member which cooperates with the wall so that the spray cleaning zone may be isolated from the sump. During such isolation of the sump and the spray cleaning zone, solvent vapors are removed to thereby facilitate introduction or removal of work into the chamber while minimizing solvent losses to the atmosphere and minimizing exposure of workers to solvent vapors.
