The particle load will get dirty real quick...I would recommend using a white scotch pad, and cleaner, regulary to keep the particles clean.  Also, never use sand paper on this ball....But once your cover starts to die a little, clean it with the white pad, and you will be golden...

Hello there...how did you end up??

The megabite cleaner and the white pad is absolutely the best combination....The white pad does not alter surface to greatly, and really deep cleans the ball...Hey, try it once, can't hurt, and after a few games, it is almost back to normal surface....it also helps the ball read the midlane better...
