Most ball manufacturers recommend cleaning the surface of your ball immediately after bowling to improve longevity of surface performance. By cleaning the ball immediately after bowling, you prevent any surface grime from penetrating into cover stock. As lane oils and other dirt penetrate the cover stock material, the ball will lose significant performance quality. Keep your ball in striking condition with these convenient and disposable travel wipes. No more bottles and messy rags to tote around. Approved for PBA and USBC competition. Unlike other spray or liquid cleaners, Strike Wipes are permitted for use during competition.
