Can you scrub it with your thumb and remove it? Yes. You can remove a few molecules of clean silver that way, too; you just don&#039;t see it until you&#039;ve altered the character of the surface. Can you reverse it, even in end stage, so that it&#039;s all silver again?</p><p><br /></p><p>Yes.</p><p><br /></p><p>Doesn&#039;t sound destructive to me.[/QUOTE]</p><p><br /></p>
