Cleaning removes chalk and skin oils; polishing restores a smooth finish after a bonded film has formed. For light dust, a soft cloth and a manufacturer-approved cleaner are enough.
Check before polishing
Dullness, a dark transfer mark, or unusual friction are useful clues. Wash and dry the ball first, because dried cleaner can mimic damage. Use one compatible product across the set rather than mixing formulas.
Safe method
Put a small amount on microfiber, work with light pressure, and buff dry. Abrasive powder, sandpaper, or a stiff wheel can remove polymer and alter the ball’s balance; they are not maintenance shortcuts.
Inspect the full set on clean cloth afterward and store it in a closed case.
