Another idea from the microbrewery I worked at was having my own keg washer. For the bigger cleaning jobs, I fabricated this table with locking wheels and a power head made of 1⁄2” copper tubing. One hacksaw cut made at about a 45-degree angle makes city water pressure work really well! The added spray nozzle on the hose shoots externally on a keg or bucket. The water is directed away, with an automotive drip pan. This setup makes cleaning almost fun.
