The Jet Carboy & Bottle Washer is a convenient device for cleaning and rinsing even the toughest grime from bottles and carboys. Simply attach to a sink or water source and press the bottle or carboy against the lever. Compressed water will shoot out the spigot, rinsing the inside with a jet of pressurized water. A metal faucet adapter may be required for proper size adjustment when attaching to a sink.
