WOW - this is the best new product we have seen in many years. Ever had a problem cleaning those 5 gallon carboys? I have, every time I use them. Well no more. Simply put a couple of liters of cleaner into the carboy, attach the carboy cleaner to a drill, insert the free end of the cleaner into the carboy and turn on the drill. Cleaning done in less than 20 seconds.
WARNING: Do not turn the drill on too fast, there is a risk of injury if the cleaner starts to wobble or go out of balance.
