Last weekend I built myself a carboy cleaner like many have here using pvc, a sump pump, and a bucket. The project was so easy to do and I got to take it for it's maiden voyage today after I racked my chocolate milk stout to secondary. OH MY GOD WHY DIDN'T I BUILD THIS SOONER. using only about 3 gallons of water total for Oxy-clean and rinsing I had a clean better bottle in only 6 minutes even with caked yeast and hop pellets from the krausen. No need to scrub, no need to soak. I just rinsed out the trub and away it went. Everyone needs to go build one of these now.
