<p>[QUOTE="Kevin Mader, post: 7688022, member: 106826"]I would soak separately in an old pill bottle for a period (could be weeks) where I would shake it occasionally to free/lift loosened debris.

I've not tried the olive oil trick, but if I were to, I'd do it after I felt that distilled water was not working any longer. Normally at that point I would put some Verdicare on it to sit for a bit...usually only an hour or less on copper...perhaps longer on clad/silver coinage. While the Verdicare is puddled on the coin, I would use a soft bristled toothbrush (cleaned between coins/uses) to gently lift any debris likely to continue attacking the substrate (e.g., stubborn verdigris).</p><p><br /></p><p>Folks might be surprised by the results of distilled water soaks and some agitation in an old pill bottle. I kept reading how the Ancient enthusiasts were soaking for extended periods with excellent results. It works better than tap water, perhaps because it's free of impurities that counteract some of the effects. Once I noted how cloudy the pill bottle water had gotten (pre shaking), I knew something was different. So I use it regularly now on metal detecting finds I'm curious about.[/QUOTE]</p><p><br /></p>
