Abstract: A pair of frustoconical bearings for supporting a roller-type applicator and carried within an elongate cylindrical container. One of the bearings is affixed to the closed end of the container while the other is affixed to a cap detachably securable to the open end. Cleaning fluid is directed to the applicator from a plurality of orifices spaced along conduits extending longitudinally within the container. The axis of each orifice is at a compound angle to urge rotation of the applicator and to urge the applicator toward the closed end of the container.
