The Blast bottle washer, made by Fermtech, allows you to easily wash bottles, carboys, tubing, and more. Attach to any faucet with a garden hose thread, or to a sink with the CE21 faucet adapter, and turn on the water. The Blast will only spray water when you push down on the the nozzle. Because the nozzle reduces to a small diameter it can be used to clean narrow items such as tubing lines
