KnockOut Ball Cleaner penetrates deep into the pores of the bowling balls (especially "reactive resin") removing residues of lane oil, dirt & belt marks. This eliminates the adverse effect the lane oil and dirt have on your bowling ball rotation. KnockOut Ball Cleaner restores the "Tac" grip to your bowling ball performance. KnockOut Ball Cleaner is affordable, easy to use and ultimately leads to better scores!
