<p>[QUOTE=&quot;BadThad, post: 1308827, member: 17261&quot;]How many of you have actually mixed mineral oil and acetone to see what happens? Acetone is a POOR choice for the removal of oils. Time and time again I see people say to use acetone and that is plain WRONG. Acetone is a very polar organic solvent and oil is completely non-polar. In chemistry there&#039;s a property we go by that&#039;s very simple: LIKE DISSOLVES LIKE. I suggest all of the people that recommend using acetone to remove oil do a simple experiment: Mix equal parts of acetone and oil in a glass container, mix well and let it stand for awhile. You will get two distinct layers. This clearly shows that acetone is the worst choice you can make when dealing with oil on a coin.</p><p><br /></p><p><b>The best (consumer) choice for removing oil is XYLENE.</b> It is a non-polar solvent that is completely miscible with oil.</p><p><br /></p><p>To the OP: Soak your coin in xylene for a couple of hours, remove, and rinse with fresh xylene. Like acetone, the xylene will evaporate but it takes a little longer. If you want, you can rinse with acetone to speed the process.[/QUOTE]</p><p><br /></p>
