<p>[QUOTE=&quot;drathbun, post: 2000448, member: 42789&quot;]Here&#039;s what I got back from my sister. First, understand that she&#039;s not a coin collector, so don&#039;t freak when she asks me why I&#039;m considering acetone rather than just using Dawn detergent and a rag. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /> As mentioned previously, my sister has for the past 10+ years managed the chemistry lab for a college, which requires her to know and follow all of the appropriate safety protocols prescribed by both the college, state, and US. When she had to move the lab to a new building it was a year-long project with very high stress levels. I trust that she knows what she&#039;s talking about from a chemistry perspective. Here&#039;s what she wrote.</p><p><br /></p><p>First, will acetone dissolve in water?</p><p><br /></p><p><br /></p><p>What about nail polish?</p><p><br /></p><p><br /></p><p>So no nail polish remover, because it might not be pure acetone. Sources for acetone as suggested here...</p><p><br /></p><p><br /></p><p>She echoed the flammable cautions raised by many here.</p><p><br /></p><p><br /></p><p>What about the characteristics of the chemical?</p><p><br /></p><p><br /></p><p>I have attached the file she sent me.</p><p><br /></p><p>How about safety concerns while using it then?</p><p><br /></p><p>I get the feeling she doesn&#039;t approve of either of those last two choices. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /></p><p><br /></p><p>And her final advice:</p><p><br /></p><p>My understanding was that Dawn or other detergents can and will affect the luster of the coins, right? I just want to do a quick dip / bath for the coins in acetone, then air dry them to avoid this, is my understanding correct?</p><p><br /></p><p>How long should the coins stay in the acetone? Do I use tweezers or something else to insert / remove them from the bath?</p><p><br /></p><p>Thanks again for the discussion on the topic.[/QUOTE]</p><p><br /></p>
