These 16 inch tynex brushes are great for stripping off floor finish and wax. The bristles have a grit impregnated into them for more aggressive cleaning applications. Not to be used as a daily scrub brush, except in those extreme situations, like factories. These brushes may be so aggressive that they will remove the finish off of floors, if used daily. *Please Note: This brush formerly had a part # of EAG-SPPV01517.
