<p>[QUOTE=&quot;Oldhoopster, post: 2665135, member: 84179&quot;]Great information.&nbsp; I thought that the sniffer just caught residual organics that did not fully evaporate.&nbsp; I can see why a simple dip in acetone or other solvent won&#039;t get rid of this.&nbsp; Are there other reaction products that can form during the &quot;conservation&quot; process, or is Copper BTA the only one?[/QUOTE]</p><p><br /></p>
