Had my ball a week now and bowled about 25 plus games with my TNV and for some reason my coverstock looks awful. I wipe it off before each throw with an oil-free towel and after I'm done bowling I apply energizer cleaner throughly all over the ball but there are still track marks very visible on the ball and in some spots in the track it seems as if the cover has worn down. Help!!!! What proceedures/steps should I take after I'm done bowling to recover the coverstock to original form. And how do I get it back to original form now?
