Here is the Rule from USBC that we are discussing.
Rule 18 – Bowling Ball – Altering Surface
While bowling in USBC competition, a bowling ball cannot:
a. Have the surface altered by the use of an abrasive.
b. Be cleaned with any liquid substance or cleaning agent.
c. Have any foreign material on it including, but not limited to, powder, rosin, marker or paint.
All bowling balls so altered or cleaned must be removed from the competition.
Note: Should a foreign substance appear on the outer surface of a bowling ball which cannot be removed with a dry towel, an approved cleaner may be used with consent from a league or tournament officer.
