LOL</p><p><br /></p><p>I&#039;ve seen your &quot;whitest cast&quot; exactly one time and I&#039;ve use acetone on tens of thousands of coins. It was due to dehydration of a very thin and unseen long-chain organic residue. I though of you when I saw it! Well, I soaked the coin in xylene and rinsed again with acetone....no more haze.</p><p><br /></p><p>You&#039;ve contradicted yourself Doug. You say rinsing with water removed the haze, it didn&#039;t remove it, it just rehydrated it. I bet if you hit it with acetone again, the haze would reappear. The water didn&#039;t remove the haze, it just made it &quot;invisible&quot;. So, your coin was rehydrated, water DID stick to the surface.</p><p><br /></p><p>You&#039;re not thinking on a small enough scale Doug. Believe me, water WILL adhere to a bare coin surface. It may only be a molecule or so thick, but it is there. By rinsing with water after acetone, you&#039;re reapplying that layer. The trick when rinsing with acetone is to immediately put the coin into a holder like an Airtite. The surface absorption of water would be almost nothing if done quickly.[/QUOTE]</p><p><br /></p>
