Abstract
An apparatus comprising multiple heating, cooling, and/or cleaning zones. The apparatus produces a jet flow of solvent/cleaning fluid onto an article to be cleaned without the need for a pump or compressor. The jet flow provides more effective contaminant removal. The multiple zones result in increased residence time for increased efficiency in separating the solubilized contaminant from the solvent/cleaning fluid.
