ABSTRACT:
High pressure washing method utilizing a hand directed spray nozzle for cleaning parts, by eye through a viewing window, and an enclosing chamber containing the parts in a manner whereby the zone for solvent spray by the nozzle is closely confined within the enclosure so as not to expose the operator or the outside environment to the liquid runoff of the solvent, or to the sprayed particles thereof, or to solvent steam or rising vapors. With a view to ecology considerations, and in addition to the concern to confine the contaminant from escaping into the environment, the internal air of the chamber and all solvent are continually recycled for re-use according to the washing procedure. Such procedure entails, in the practice of the instant invention, keeping down the vapor concentration by defogging the chamber air, and simultaneously defogging the viewing window through blanketing same by the defogged air as recycled.
