<p>[QUOTE=&quot;Oldhoopster, post: 2756252, member: 84179&quot;]EZest contains Sulfuric Acid. I don&#039;t like mixing ammonia and acids so i would stay from that (I&#039;m too lazy to work through the chemistry and I don&#039;t know how it reacts with the other active ingredients).&nbsp; A baking soda solution should neutralize any remaining acid, but is probably overkill.&nbsp; If you use a baking oda solution, make sure that is rinsed well also.&nbsp; </p><p><br /></p><p>JeffB mentioned rinsing in 3 separate jars of distilled water.&nbsp; I really like this technique (wish I would have remembered this and included it my earlier posts <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie20" alt=":banghead:" unselectable="on" unselectable="on" />) The concentration of acid in EZest shouldn&#039;t be too high so 3 rinse jars should work well.&nbsp; If you&#039;re doing more than a few coins at one time and really want to be safe, change the rinse jars often.</p><p><br /></p><p>And Like I said in a previous post, my personal preference is to use distilled water, not tap water.&nbsp; Not a huge risk, but why take a chance[/QUOTE]</p><p><br /></p>
