There is disclosed an apparatus and method for cleaning and processing highly soiled articles, such as commercial oil-impregnated dust mops and cleaning cloths, in a closed, relatively pollution-free cycle in which the soiled work is cleaned by immersion and tumbling in large volumes of the impregnating oil medium in a succession of cycles and in which a plurality of reservoirs of the oil medium are maintained having different degrees of soil impurity and in which the most contaminated batch is recycled through a continuous filter utilizing an expendible filtering medium and a vacuum to achieve a dry waste disposal composed of inert filtering material, inert soil, and insignificant quantities of residual oil.
