The pad supports the cleaning of any bowling ball. Spray the bowling ball well with the aforementioned cleaners and spread the cleaner well over the ball with the pad. For seriously stuck-on dirt, press hard with the pad on the ball until the dirt is dissolved, then dry with a clean cloth. If there are still small particles of dirt on it, the pad can also be used dry, so you can better see whether these dirt particles disappear, however, wet is preferable!
