The first brush designed for both glass and plastic fermenters. Featuring a plastic coated wire handle to prevent scratching in plastic carboys and Fermonsters, but still rigid enough for glass carboys. 24” long, braided wire and nylon bristle construction. Fits all our plastic, glass, and Fermonster style fermenters. Besides plastic and glass carboys, this is also useful for cleaning the inside shoulders of 3 and 5 gallon kegs.
