<p>[QUOTE=&quot;lordmarcovan, post: 5392847, member: 10461&quot;]Acetone, being a solvent, is good for removing things like paint or lacquer or adhesive residue.&nbsp; Its effects on plain old circulation grime may be a mixed bag, but I think in most circumstances it is OK to try, and shouldn’t usually affect the toning on a coin unless that toning is caused by some artificial, chemical means.</p><p><br /></p><p>As to removing Vaseline or mineral oil from a copper coin, one simply wipes it off with a clean, soft cloth, paper towel, or tissue.&nbsp; (I usually use an old cotton T-shirt.) It will take the loose dirt off with it, and leave the coin with a nice glossy appearance after all the excess Vaseline is wiped off.&nbsp; This should not affect a coin’s original color as long as you’re not scrubbing at it too hard. Just gently wipe, is all.&nbsp; You can wipe firmly, but you don’t want to <i>polish</i>. </p><p><br /></p><p>You want to leave the natural brown intact and avoid making the coin too shiny or orange-looking by exposing the raw copper underneath the “skin” of natural toning that developed over time.</p><p><br /></p><p>Water will not wash off Vaseline or oil unless it’s boiling hot.&nbsp; It will just bead up.</p><p><br /></p><p>To paraphrase the immortal Mister Miyagi, “wipe on, wipe off”.</p><p><br /></p><p><img src="https://media.tenor.com/images/e95c8d2fa895941f79529484f104476e/tenor.gif" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
