First let me say that I'm not on any staff, I dont get paid for anything in bowling and I dont get any free items either. Anything bowling related that I have, I pay for full price.
Now with that out of the way...That Purple Stuff is the best cleaner that I ever used. I dont use it after every shot but I use it after every game. Actually I do have it on my towel and it stays moist and I do wipe my ball off after shots..BUT I clean it after every game. The main result that I notice is that my balls reaction is as strong as it was out of the box 60 games later so far. With a lot of high end balls in the past Ive lost reaction after 30 or 40 games. So far, several new balls to start this season and not one lost its reaction. Test it out for yourself and save your balls life!
