The Jet Carboy & Bottle Washer is an excellent solution for cleaning any size bottle or carboy. Simply attach the washer to a faucet and invert your container over the washer's spout. A powerful stream of water is directed up into the inverted container, cleaning in seconds. The stream automatically shuts off when the container is removed. The washer natively fits garden hose thread faucets, and an adapter for kitchen faucets
