Bottle Sanitizer/Rinser. This unit consists of a reservoir for water or SO2 solution and a spring loaded pump. It has a screen to filter lint out of the recirculating water. To operate, push the bottle down three or four times while it is placed over the pump mechanism. It may require a few extra strokes to prime the pump for the first bottle. The unit may be used by itself or mounted on one of the bottle draining racks.
