An aqueous parts washing machine includes a main tank and a submersion tank disposed within the main tank. The submersion tank is supported in spaced relation from the walls and floor of the main tank. An aqueous cleaning solution fills the submersion tank and partially fills the main tank. A pumping system circulates the cleaning solution within the submersion and main tank. The pumping system includes a pump for drawing solution from the main tank and a solution agitation member for receiving solution from the pump and injecting the solution into the submersion tank to agitate solution within the submersion tank. The pumping system further includes a sparging mechanism for projecting solution from the pump across an upper surface of solution within the submersion tank to skim an oil deposit on the upper surface over an edge of the submersion tank.
