Storm U Clean U Score Bowling Ball Cleaner- 8 OuncesWith its original formulation, U-Clean U-Score delivered consistent, repeatable performance for all. But lane conditions, lane surfaces, and lane oils have changed significantly. That’s why we are introducing a new and improved version of the product that launched the Storm brand. Modern urethane bowling balls very easily get saturated with oil which decreases performance. U-Clean U-Score quickly and easily restores the performance of ALL urethane bowling balls.
