<p>[QUOTE=&quot;-jeffB, post: 3930619, member: 27832&quot;]I&#039;ll defer to your actual experience, but I&#039;d expect a pressed Zincoln to foam up like a rabid dog if you dipped it in lemon juice and salt. Between the acidity, the high conductivity, and the chloride ions, I&#039;d expect the exposed zinc to dissolve rapidly, and I&#039;d be nervous about getting enough of the chloride off to protect the piece against humidity going forward. (The zinc <i>should</i> protect the copper layer as it rots away, but after exposure to acid chloride I wouldn&#039;t even count on that.)</p><p><br /></p><p>Edit to add: Chloride ions plus any other oxidizer, even air, can definitely attack copper. You don&#039;t even need the acid, but it does speed things along. <b>Keep the salt away from copper</b>, unless you want to keep cleaning the piece repeatedly until it&#039;s completely corroded away.[/QUOTE]</p><p><br /></p>
