After hearing of my disappointment with acetone on my Peace Dollar Dr. Roommate suggested that I try citric acid. &quot;As in grapefruit juice?&quot; I asked, but have not heard back from either.&nbsp; What about that?</p><p><br /></p><p>Edit: I should point out that both of those guys think that my Dollar must have been in contact with something that was rusting for several years.[/QUOTE]</p><p><br /></p>
