The Clean Plug beer faucet plug both keeps fruit flies out of your beer faucets when not in use, and scrubs them clean with an integral nylon brush each time you insert and remove the plug. 2½ inches long. Fits all beer faucets.
To use: Before insertion, rinse the plug with warm water and shake dry. Insert the brush end first into the faucet opening until the plastic plug firmly seals the opening. Leave in place overnight. When removing, twist the plug to gently scrub the inside of the faucet.
To clean: Rinse with running water to release beer faucet residue from the brush. Occasionally soak the plug in a dilute sanitizing solution and then rinse before using.
