<p>[QUOTE=&quot;Oldhoopster, post: 3022179, member: 84179&quot;]I absolutely agree with Jim.&nbsp; It is highly unlikely that anyone is going to clean coins under those conditions.&nbsp;&nbsp; IF you somehow manage to get copper acetate to form on your Red BU copper coin, how thick a build up do you need before you can detect any color change?&nbsp; How long does it take?&nbsp; This test was done on clean copper foil.&nbsp; Will the reaction and reaction rates apply to brown and red/brown copper with surface oxidation?</p><p><br /></p><p>I think I&#039;ll stick with acetone and use the short dip, or qtip method that I always use.&nbsp; Follow it with a thorough rinse.&nbsp; I like distilled water for the rinse because you don&#039;t have to worry about any minerals that might be left behind as tap water evaporates, but in reality, mineral spots won&#039;t be an issue for most people and the coins the clean with acetone.</p><p><br /></p><p>And don&#039;t forget, the single research paper is reporting on the formation copper acetate.&nbsp; There are no research papers reporting on any silver or gold reactions with acetone.[/QUOTE]</p><p><br /></p>
