The Tenth Frame UltraClean Ball Cleaner is heavily used in my area...seems like everyone has a bottle of it in their bag. This product interests me because it is included on the ABC/USBC list
http://www.bowl.com/specs/ballCleaner.aspx as "Not Acceptable at Any Time", which means that this substance is not ever allowed to touch the ball surface. The ingredients on the bottle shows that it contains some Acetone, which may be the primary reason why it is not allowed and why it removes belt marks so well. I've tried it and yes it does work quickly and easily with a dry towel. It's much easier to use than the legal Ebonite Powerhouse cleaner.
This raises some questions for me:
1). Why would Tenth Frame even make a cleaner that is "Not Acceptable at Any Time"? As you can see on the list, there are 101 accepted cleaning products and 8 that are "Not Acceptable at Any Time". It seems that they could have found a way to make the product acceptable AND work good at the same time.
2). Isn't there a chance that the product could alter/damage the ball surface since it does contain some Acetone? Considering it is packaged in a plastic bottle, the levels of Acetone must be really low. Otherwise it would eat through the bottle.
3). If someone was seen applying this cleaner to their ball before sanctioned competition, could they be sujected to a penalty?
