<p>[QUOTE=&quot;-jeffB, post: 2663052, member: 27832&quot;]Remember that <i>boiling</i> water isn&#039;t the same as <i>distilling</i> it.

There&#039;s no guarantee what puts the clouds in it, but it&#039;s probably nothing good for coins, and ammonia itself isn&#039;t very safe -- I&#039;m not <i>sure</i> it would actually attack coins, but it likes to form &quot;complexes&quot; (loosely bound chemical compounds) with metals like copper and silver, and I&#039;d worry that it might cause some etching, especially if mixed with the wrong &quot;other stuff&quot;. It&#039;ll definitely attack zinc.[/QUOTE]</p><p><br /></p>
