Brick, I'm overly cleaning both hers and mine. After every set, I use Abzorb-it, let it set on half the ball for 12 hours, other half 12 hours. Then Clean N Dull. Keep in mind, I have a pro shop, I have the time and cleaners.
I use CPR every now and then but Abzorb-It is cheaper and works just as well.
