[QUOTE="Oldhoopster, post: 4959616, member: 84179"]This is the only scientific paper that I have seen that says there is a reaction between acetone and copper [URL]https://www.stonybrook.edu/vescalab/research/research7.html[/URL] They found if copper is exposed to acetone, acetic acid (same stuff in vinegar) can form which, in turn can form copper acetate crystals This can occur if all of the following conditions are met 1) exposed to light, 2) exposed to water vapor, 3) the acetone completely evaporates, 4) total exposure time was 18 hours. I use short soaks of 5-10 minutes max, and rinse with water (distilled if I have it) immediately afterwards, and have never had an issue using acetone to remove PVC plasticizer residue from copper. If anybody has any additional references that indicate acetone is bad for copper, please post them.[/QUOTE]
