<p>[QUOTE=&quot;-jeffB, post: 1389744, member: 27832&quot;]The 91% isopropanol is a constant-boiling mixture, or &quot;azeotrope&quot;, with water. What this means is that it does contain water, which can react with some metals, but it takes ALL the unreacted water with it when it evaporates. In other words, 10 ounces of 91% isopropanol won&#039;t evaporate and leave 1 ounce of water behind. It stays 91% isopropanol until it&#039;s all evaporated (or until something adds more water to it).[/QUOTE]</p><p><br /></p>
