Pool balls that have been polished are not allowed in professional pool tournaments. The BCA rules strictly prohibit polishing pool balls in a tournament. I realize the presumption is aren’t brand new pool balls polished? I suppose that’s logical to presume but pool balls that have been cleaned and polished are verboten under the equipment specs. Dr. Dave produced a segment about polished pool balls and how cling is affected but local tournaments do as they please since the pool balls are used daily for commercial play. Some rooms don’t even clean their balls daily which is likely due to employee laziness.
