Start with a thorough cleaning (Track's Clean and Dull or Neo-Tac's Hook-It) and, then a treatment with Doc's Elixir. Get a Micro-fiber towel and wipe the oil off after every toss. Clean the surface after every league session. Re-treat with the Elixir after every 25+ games or so. When ball's track get so that it is rolling too early, re-surface according to the manufacturer's process.

charlest is right on. Track Clean n Dull, or neo tac Hook-it will clean it deep enough. I had a Recovery and followed Track's instructions on the clean n dull bottle. I used a green scotchbrite pad (600grit) and put some clean n dull on it and went over the entire ball. Worked great. That should work very well on the WOW as well.

To resurface, I prefer scotchbrite pads----the ideal thing to do is start with 400 grit (burgandy scotchbrite) go over the entire ball, then go to 600 (green pad). Once you have gone over the entire ball with green pad that is good condition---follow it up with a well worn green pad. This will smooth the surface out and put it very close to box condition.

goodluck
