<p>[QUOTE=&quot;Clawcoins, post: 3473623, member: 77814&quot;]btw, with copper washes, you have industrial/ commercial/ shop types which can be consistent, etc and then you have home stuff which can be inconsistent.</p><p><br /></p><p>I use spare acid to clean coins.&nbsp; I actually indirectly copper wash many coins.&nbsp; The copper as it falls in the solution, if you do not agitate the container, will just fall directly down in a sense. It won&#039;t get copper (as much) on the top surface.&nbsp; And if you have coins not really stacked, the copper wash would only cover part of the surface, the one not covered.&nbsp; And you can get partial copper wash on the top surfaces, the bottoms wouldn&#039;t have copper or maybe very lightly.&nbsp; And any weird stains can transfer through the solution too.&nbsp; I&#039;ve posted some in the past.[/QUOTE]</p><p><br /></p>
