<p>[QUOTE=&quot;CygnusCC, post: 8456883, member: 120299&quot;]Yup, I got a cheap noname brand ultrasonic cleaner through Amazon <a href="https://www.amazon.com/dp/B0B6PG8TTK" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.amazon.com/dp/B0B6PG8TTK" rel="nofollow">https://www.amazon.com/dp/B0B6PG8TTK</a></p><p>I can&#039;t say I love it because the cycle only lasts for a few minutes, then shuts off and can&#039;t be restarted for at least that long. However, the end result was that it did a pretty good job of removing that black residue after several cycles. I rigged up a couple coated paperclips to hold the coin suspended vertically - it worked pretty well.</p><p><br /></p><p>I&#039;ve never tried MS70, though. I&#039;ve tried using Conserv to dissolve with in the past, but I don&#039;t seem to get any better results from that than just using acetone.[/QUOTE]</p><p><br /></p>
