Not only safe but extremely effective.  Mo Pinel even recommended it for Mo-rich bowling balls.  Really easy and mess free if you own a dishwasher.  Google dishwasher to de-oil ball.  Been covered many times.  Depends on what you have on hand and how much you like to spend money you don't need to.

Actually, when Morich's website was completely active in English, his first choice for de-oiling a ball was to use a Revivor machine. He recommended water as a second choice if a Revivor was not available. A recent example of Mo Pinel's endorsement of dry heat can be found in Bowlingchat:

I hope this clears up any confusion you might have on Mo Pinel's assessment.


As far as "spending money you don't need to", please clarify that many dishwashers raise water temperatures to levels that exceed ball manufacturer heat warranty limits. Many readers will take your comments on dishwashers that it's a method that safely works in all cases.

No confusion on my part. 

Good. Then that means:


1)  You understand you've been misrepresenting Mo Pinel's position on his prefered method for oil extraction.


2)  You understand that some dishwashers can actually be harmful due to unsafe water temperatures for ball de-oiling.


I'm glad we have common ground on the subject.

So instead of just admitting you gave out incorrect information and setting the record straight, you delve into fantasy about my statements being "shot down".

If you haven't misrepresented Mo Pinel's position on the preferred method for oil extraction, please provide an appropriate link. Prove me wrong. The ball is in your court. In the mean time, I'll provide still another Pinel position statement for you to read and hopefully embrace:

And my statement about dishwashers was simple and clear -- many modern models automatically heat water (in the most basic Normal mode) to temperatures that exceed some ball manufacturer warranty limits. Period. All this nonsense about "sanitation cycles" and "building codes" is a superfluous tap dance you injected to avoid having a rational discussion. 

We're here to discuss and provide accurate information that all can take advantage of. If you're really about "posting the honest truth", then demonstrate it. Nobody is going to think less of you for admitting you didn't understand specific facts about the application of heat.

acetone can mess up the coverstock i have been told over the years. with how short a period of time the coverstock last these days  you do not need any more help wearing it down.

No, denatured alcohol isn't the same thing as acetone, but both are illegal by USBC rules.  Isopropyl (rubbing) alcohol is legal, but isn't very effective.  --  JohnP

To the original topic, has anyone actually destroyed a ball using acetone as a cleaner over an extended period of time?? I know it can melt plastics and resins, but I'm curious if anyone here has taken acetone cleanings to that point. Thanks.

I used to use it all the time. Never ran into a single problem. Now I would use it to revive oiled up covers and I would see color transfer to a paper towel with it. I stopped using it years ago when I discovered the "warm" setting on my oven. It runs at an even 120. That makes life a lot easier, and more legal...
