The "Self Contained" Glass Washer is made from durable, blue plastic material, and features an oval rim with soft rubber ring to protect your glassware during insertion and removal. The Glass Mug Washer is designed to clean every part of your glassware, from the outside to the hard to reach inside. The nylon brush bristles will thoroughly wash your glassware, but are soft enough to protect against scratching the glass surface. The four strong suction cups attached to the bottom will prevent the unit from sliding during cleaning, and allow you to work quickly and efficiently. Stands 10.25" tall with an 8" (widest point) diameter.
