Abstract: A portable device for washing drinking glasses includes a hollow tubular handle containing a rotary shaft, drive motor, and dry cell battery. A circular sponge cleaning element is attached to the external end of the rotary shaft for cleaning the interior surface of a drinking glass enclosing the sponge element. The hollow handle provides a storage chamber for liquid detergent that can be delivered through an axial passage in the shaft to the sponge element. Handle construction is simplified by forming the handle in two sections split on the handle longitudinal axis; a single gasket is interposed in the plane of the split to seal the longitudinal joint between the two handle sections.
