Aqueous cleaning method

A method of removing contamination from the surface of an article which includes the steps of:

• moving the article along a continuous path through a pre-wash station, a wash station, a rinse station, a final rinse station, and a plurality of drying stations,
• applying a liquid to the surface of the article at each of the pre-wash, wash, rinse and final rinse stations;
• providing an aqueous cleaning solution at the wash station and non-contaminated water for said application at the final rinse station;
• circulating the applied water from the final rinse station to the rinse station for said application at the rinse station;
• circulating the applied water from the rinse station to the pre-wash station for said application at the pre-wash station,
• removing rinse water from the article surface by blowing heated air onto the article at a drying station,
• each of said stations being separated by wall structure having an opening formed therein to provide for movement of the article therethrough, and at least one of the wall openings having air under pressure provided to form an air curtain adjacent said one of the wall openings, and
• removing adsorbed water vapor from the article surface at a subsequent drying station by subjecting the article to a plurality of heat lamps, and removing residual desorbed water vapor from the article at a next drying station.
