A brass fitting that attaches to the end of a hose or a mop-sink faucet, the Bottle Jet is shaped like a check-mark. A brass tube protrudes downward from the base, then angles up towards the user, with a trigger lever on the end. When the lever is depressed, a high-velocity jet of water is sprayed from the end. This is an invaluable tool for cleaning bottles and carboys. The neck of the bottle/carboy is placed over the tip of the jet, and when pushed down far enough, it triggers the lever and spray-cleans the inside of the vessel.
