<p>[QUOTE=&quot;Oldhoopster, post: 3173033, member: 84179&quot;]That would be a good experiment. I did a quick lit search and didn&#039;t find anything significant on Aluminum reactions with acetone. Usually a very thin layer of aluminum oxide layer that forms on the surface. Al2O3 doesn&#039;t really react with much at room temps so as long as you don&#039;t have something that&#039;s removing this layer, I you should be OK. </p><p><br /></p><p>I don&#039;t have any reason to doubt the credibility of members that posted about the acetone reactions, so that&#039;s what makes this interesting. In some ways, I think it&#039;s similar to the claims that acetone adversely affects copper (the SUNY Stony Brook paper only shows Cu acetate formation under conditions that wouldn&#039;t be used in normal coin conservation).&nbsp; I believe the acetone my be reacting with a secondary material and not the aluminum itself[/QUOTE]</p><p><br /></p>
