Keg and Carboy Washer. I own and use this cleaner and I love it. It works great on a variety of equipment including kegs, buckets, carboys, tubing, small parts and pieces, Speidel Fermenters and more. Check out my extensive hands on review. A small fitting purchase also converts this to a draft line cleaner.
