I like to use Clean n Dull on the spinner for polished balls. Ofcourse, as was already mentioned follow it up with water to clean the residue off of the ball.
For dull, or matte finishes I prefer to do it by hand. Clean n Dull, a scotchbrite pad and very little pressure deep cleans a ball tremendously!!!
