The Blast Bottle Washer from Fermtech is probably one of the most useful tools in the home-brewery.
It attaches to your sink faucet (with Hose Adapter), or to any male garden hose fitting. It not only washes
your bottles, it's great for washing carboys and the tip is designed to fit your transfer tubing, so you can
blast out your tubing, as well. It has also been designed to reduce "hammering", so it is easy on the plumbing.
