<p>[QUOTE=&quot;SuperDave, post: 2385402, member: 1892&quot;]You don&#039;t &quot;remove&quot; polishing; it&#039;s a physical alteration, not a chemical one. Just like hairlines, the only way to remove a physical alteration like that is further physical alteration, in this case some time in your pocket with other coins. &quot;Circulate&quot; it.</p><p><br /></p><p>Insider, I had in mind a somewhat &quot;softer&quot; solution in liquid suspension, using currents - convection currents or otherwise - to cause the contact. It would be far slower, but patience is the key to the difference between cleaning and conservation.[/QUOTE]</p><p><br /></p>
