Why I need a carboy cleaner: 12 hours of soaking, 11 words of profanity, 10 prune-like fingers, 9 percent ABV beer trub, 8 aching muscles, 7 filthy rags, 6 gallons of waste water, 5 puddles of spillage, 4 slips on the floor, 3 filthy brushes, 2 ounces of dry hops, and a container of PBW in a pear tree.
