<p>[QUOTE=&quot;Kentucky, post: 4349498, member: 33176&quot;]A pure solvent of any kind would not leave a residue.&nbsp; Now you might argue that a solvent that is 99.99% pure still has 0.01% impurity, but the impurity itself might be volatile.&nbsp; OTOH, &quot;distilled of soapy water&quot;...distilled water should not leave any residue while soapy water should be thoroughly rinsed or you have problems.&nbsp; Now, consider any surface impurities that your solvent has dissolved could still re-deposit as the solvent evaporates, one of the reasons I like to pat or blot coins dry.[/QUOTE]</p><p><br /></p>
