The Double Tee Stem Cleaner targets one of the most difficult-to-reach areas for cleaning. Regular use will decrease buildup and stripping problems. The machine is self-contained, rides easily on multiple forms and is easy to transport. The cone-shaped brush is made up of multiple disc sections in varying diameters configured to fit the stem width and depth of your double tee. Brush assemblies easily interchange for machine use on several different cross sections.
