I bottle in 22oz bottles. I reuse the bottles if they are returned.I applied a very thin layer of "keg lube" to lubricate the spiral wound shaft. It worked marvelously!It won't do all the work for you. You do have to push & pull it from the bottle, but it knocked off the crud inside the bottles before I sanitized them for reuse.Much easier than a nylon bristle brush for the stubborn stuff!For storage, I found the rubber washer, (placed between the bottle & force face of this tool), can be lightly stretched to store on the handgrip to stabilize the spiral shaft. When I use it, just stretch it a bit & pull it back over the the grip to engage the bottle neck opening.Great tool after one gets used to it!
