A parts washing method which utilizes a centrifugal filter to substantially reduce the need to replace its solvent. Solvent in a washing basin flows down a drain in the parts washing basin, through a screen to a centrifugal filter assembly, with a disposable filter in the filter receptacle of the centrifugal filter assembly. Thus the contaminated solvent flows from the drain, into a disposable filter element located in a spinning filter receptacle, where centrifugal force draws the solvent back into the solvent container while the materials washed from the part remain in the disposable filter element. The clean solvent is collected in a reservoir and recirculated back to the wash basin.

1. A method of cleaning parts with a solvent while maintaining a relatively high degree of purity of the solvent, said method comprising:a) placing the parts to be washed in a wash basin; b) causing the parts to be washed with solvent in the wash basin; c) directing the solvent from the wash basin to flow by the force of gravity from the wash basin to a centrifugal filter and operating the centrifugal filter to separate from the solvent impurities in the solvent; d) collecting the solvent separated from the centrifugal filter in a reservoir; e) recirculating the solvent from the reservoir back to the wash basin for further use in washing parts in the wash basin.
