Going green is easy and profitable with the Washmaster, a fast and portable cleaning tool for all types of drywall tools (automatic taping tools, skim boxes, etc.) and other hand tools. Roll the product on its flat-free tires anywhere in the work area. Fill the product with 15 gallons of water, add the specially formulated, environmentally friendly Washmaster Juice into the tank and start cleaning. The juice eliminates foam and separates the drywall mud from the water in a matter of minutes, sending the mud and debris to the bottom of the tank.
