<p>[QUOTE=&quot;Bullionbound, post: 765, member: 79&quot;]I have not done this myself, so take it all with a grain of salt: Acetone is supposed to be the best method for cleaning coins up without removing any surface metal. The trick is to make sure that (after) you run a lot of water over the coin before allowing it to dry. A residue of acetone will haze your coins if they are proofs. An even better way is to then dip the well-washed coin in ETOH, as the ethanol is highly volatile and will evaporate rapidly. Get the highest percentage ETOH that you can find in the pharmacy. Careful, rubbing alcohol is isopropanol, which is much less volatile than ETOH. People recommend letting the coin air dry for up to 2 weeks before storing away. I would try on those less desirable pieces before jumping in with your pride and joys.[/QUOTE]</p><p><br /></p>
