I know that in a sanctioned tournament you cannot alter the coverstock of the ball in anyway once you start. But my question is, I use tape in my thumb hole and I've been having issues where when I pull the tape out, it's leaving the sticky crap behind it. The only way I can clean the ball at home is by using like acetone on a rag or something to clean it out.
Now, if I'm in a tournament and I pull out the tape and have the sticky stuff left, can I go to my bag and put acetone on a towel and clean out the thumb hole? or is that illegal? I would not be touching the cover at all, just a towel in the thumbhole.
Thanks
