<p>[QUOTE=&quot;NOS, post: 158153, member: 2098&quot;]Electrolysis should be left to the professionals. Back when I was into buying &quot;uncleaned Ancient Roman coins&quot; I got into electrolysis and I had very few positive results. It often takes away all of the patina on a coin and on quite afew it ate away the outer layers of the metal so I thought it was dirt and would try and clean that off! Now a good portion of those coins which survived intact for the last 1800 years in the ground look hideous and very abrasive after just a few minutes and are worthless. Olive oil and a toothbrush is really the only way amateurs such as myself should go, or not at all.[/QUOTE]</p><p><br /></p>
