The results were that it blew off all loose dirt that I <a href="http://www.forumancientcoins.com/numiswiki/view.asp?key=had" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.forumancientcoins.com/numiswiki/view.asp?key=had" rel="nofollow">had</a> worked up, seemed like it was a little faster at getting a coin clean. Then I looked around for a low powered air compressor and came up with this.</p><p><br /></p><p>It&#039;s called a Datavac, but is not a vacuum, it is a duster or blower mostly designed to blow out PCs and keyboards.

You can wipe the coin off and dry with a soft cloth and then use the blower to get the rest of the water off and a lot of moisture. Let the coin set for about 10 minutes and then blow it off again.
