This process concerns a drum-type continuous washer for small parts, e.g., fasteners. The parts, requiring oil or soil removal, are tumble washed therein. The process comprises passing parts in order through an immersion station for tumbling the soaking parts in hot washing liquid, a liquid-impingement station for loosening and spraying off the wetted soil by the force and cleaning action of impinged, hot sprays of continuously recycled washing liquid, a drip dry station for tumbling off excess liquid from within and without the individual tumbling parts, leaving them wet and hot, a blow-dry station for rendering the hot parts damp by means of compressing and blowing hot wet air drawn from the chamber and preferably containing rust inhibitor coating material, and an evaporative final dry station for rendering the cleaned, hot, rustproofed parts essentially moisture free.
