Dan its just an old outdated rule that has no bearing on todays game.
Why hasnt USBC sent a letter to every proshop and inform then not to use Acetone bowling balls since 99% of them use it ?
The rule will bechanged and adapted to todays game sooner or later.
How many 300s or 800s have be shot because of Acetone ?...Nil discussion IMO.
Acetone is just another solvent/cleaner that works very well.
Also, if USBC can enforce the rule, then why is it a rule ?
