Abstract: An apparatus for cleaning vehicle parts includes a reservoir containing a lower layer of water and an upper layer of solvent, a fluid pump for conveying solvent from the solvent layer to the parts to remove dirt and grease therefrom, a solvent collector for feeding the used solvent to a plurality of sequentially arranged settling tanks and a filter for receiving the solvent from the settling tanks and removing suspended particles therefrom. The solvent passes through the filter and the filtered solvent is discharged into the water layer of the reservoir. The lighter-than-water solvent rises to the solvent layer, leaving particulate matter behind in the water layer.
