  • Patent number: 5809604
    Abstract: A tile grout brush for cleaning grout between tile includes a main body having a generally triangular configuration with an open central zone and including a base portion, a first handle portion and a second handle portion. Bristles are fitted to the base portion and extend from a bottom, outward facing side thereof; the bristles being disposed in bundles arranged in longitudinal rows substantially along a length of the base portion. The first and second handle portions are structured and disposed to promote grasping thereof in order to apply force and reciprocating motion to the bristles against the grout and tile. Threaded sockets are provided on the main body for removable attachment of an elongate extension pole at various selected angled positions relative to the base portion so that the brush can be manipulated to clean areas that are difficult to reach.
