He told you a bunch of BS. Yes, you can use a micro fiber towel. All it does is take dirt, grime & oil off of the ball. You cannot use anything that alters the surface finish of the ball, such as scotch brite or sand paper. Also, you cannot put polish that has an abrasive in it on your towel or for a product to be approved at anytime, the product must not soften the ball surface or leave a residue. USBC has a list of cleaners allowed during competition & a list for after competition. They also have a list of products that are not supposed to be used ever.
Edited the polish portion of my initial reply. How''s that?
