<p>[QUOTE=&quot;SuperDave, post: 2632758, member: 1892&quot;]Well, if you&#039;ve never used acetone....</p><p><br /></p><p>Use it as if it&#039;s the most flammable thing you&#039;ve ever handled. <b>Because it is</b>. Of course, the advantage of using a substance so volatile is, if you want to rinse it in something after using, it will all have evaporated before you can get the coin into whatever you&#039;re rinsing with. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>Point being, unless you&#039;re handling a coin so cruddy that stuff will be suspended in the acetone and possibly redeposited on the coin before you get it out, you do not rinse after acetone. And if you do, you use clean acetone as the rinse. The acetone itself will literally vanish without a trace from the surface of the coin. Nothing will remain of the acetone; no chemical detector can detect it&#039;s use because <i>it leaves nothing behind</i>. Just like any other liquid, though, acetone can hold debris in suspension, so just like you wouldn&#039;t rinse in dirty water, don&#039;t rinse in dirty acetone.</p><p><br /></p><p>For your case, a second rinse won&#039;t be necessary unless the dealer was eating fried chicken at the same time he was examining your coin. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>As regards flammability: Treat acetone like gasoline when it comes to considering ventilation. You&#039;re not going to be using any more than a few ounces, and even then only briefly, but all the same put yourself in a place with decent ventilation for the process.[/QUOTE]</p><p><br /></p>
