Fermtech has done it again! The double blast bottle washer sits in your sink, attached by a length of tubing to the faucet. This eliminates stress caused by washers that mount directly on your faucet. Wash not one, but two bottles at a time! It also includes an attachment made especially for cleaning and rinsing carboys. This has the same garden hose fitting as the jet washer and immersion chiller, so a metal faucet adapter may be required for proper size adjustment when attaching to a sink.
