The Mark II Keg & Carboy Washer is a great way to clean your corny kegs, de-speared sanke kegs, as well as carboys. A powerful 520 GPH submersible pump circulates cleaner or sanitizer through your carboy or keg. This recirculation uses less water and provides a superior cleaning action when compared to normal soaking. Stubborn krausen lines or tartrate crystals are quickly broken down while you are free to focus on other tasks. The included fittings allow thorough cleaning of corny keg posts and dip tubes, tubing, and racking canes.
