Then dip the coin in the next bowl, and then dip it again in the next bowl. Some are going to argue this next step but I would never skip it - dip it in a clean bowl of distilled water. Then stand the coin on edge (lean it up against something like the countertop backsplash) on a soft cotton towel and allow it to air dry. DO NOT try to pat or dry the coin in any way with a cloth. Do it just like I said.</p><p><br /></p><p>Do this with one coin first. If it works on that one it will work on the others. If it doesn&#039;t - you&#039;re out of luck.</p><p><br /></p><p><br /></p><p>edit - one last thing. It is necessary to use new acetone for each and every coin. At no point can any of the acetone be used again. It has to be thrown out every time.</p><p><br /></p><p>And DO NOT pour it down your sink drain ! Or any drain. Put in a metal can and then dispose of the can.[/QUOTE]</p><p><br /></p>
