The QEP Grout and Tile Cleaning Brush has been redesigned for easier use. A thumb rest has been added to the handle to improve leverage and reduce fatigue. On the opposite side of the bristles we added a square edge that can be used for scrapping by simply turning the brush over. The nylon bristle design now works even better on all grout joint widths and will last longer than the earlier version. We think you will love the new design and the improved results of this multipurpose brush, whether using for grout and tile cleaning or any other job around the house, patio, garage, car, camper, boat, motorcycle or trailer.
