So all acetones are not created equal? Regular acetone will harm coins?

If you look or check out search on this forum you would probably find millions of posts on this subject. Slight exageration of course. The main problem is shelf life and packaging. If you saw the canning process you would understand the possible errors that could happen to such products during the coating process. Any small omission on the inside could allow the Acetone to slowly absorb the metallic contents of the can itself. This is why most pure Acetones are from glass containers. An experiment done many hundreds of years ago by a chemist to make pure water and then he contained it in a glass bottle. Today this is still in a Museum and the water is all cloudy. The water absorbed some of the glass.
Meanwhile back to the original quesstion. Don't mean to be pessimistic but I think a little to much is being done to preserve coins. I've been collecting coins for well over 60 years. Have well over 100 Whitman Classic Albums. Each one is in a plastic Zip Lock bag with as much air pushed out as possible. Many, many of my coins have been with me from the beginning since I never sell any coins. NONE have shown any toning, corroding, tarnishing, etc. Naturally I also have thousands of coins in 2x2's, plastic rolls, jars, etc. Those also show no signs of any problems.
Am I just lucky. I doubt it. No air or moisture gets to my coins as they are so no massively over kill is required as far as I can tell.
HOWEVER, it probably doesn't hurt to be over protective.
