<p>[QUOTE=&quot;BadThad, post: 518391, member: 17261&quot;]Hello!</p><p>&nbsp;</p><p>First off, Jim, thank you for perfoming this test. Being a scientist, I really enjoy seeing VERDI-GONE™ customers doing experiments such as this.</p><p>&nbsp;</p><p>My background: I&#039;m a chemist of 22 years in the metal working fluid industry. I&#039;m primarily an analytical chemist, but I&#039;m also very involved in product development and regulatory affairs. My expertise is in the interaction of metal surfaces and fluids.</p><p>&nbsp;</p><p>I&#039;m an avid collector of Lincoln cents. I have a complete collection and few thousand more. They are my true love of collecting!</p><p>&nbsp;</p><p>I&#039;d be happy to answer any specific questions about VERDI-GONE™. After a quick read through this thread, I&#039;d like to address a couple questions that came up.</p><p>&nbsp;</p><p>- VERDI-GONE™ is unlike ANY other product on the market. It was invented for ME and only for my use. I only started selling it due to multiple collector requests. After a lot of frustration with trying all the classic methods for removing verdigris, I decided to develop a product that works rapidly, yet generally maintains the original patina of Lincoln cents. It is NOT based on any other commercial product, it is a one-of-a-kind formulation based on a proprietary, laboratory reacted molecule. VERDI-GONE™ is designed to only remove/react with verdigris, it is NOT a cleaner. It is a copper conservation fluid. Other commercial products are based on harsh chemicals and often contain detergents or other cleaning agents that will permanently damage/alter the copper surface. Another reason I developed VERDI-GONE™ for myself.</p><p>&nbsp;</p><p>- VERDI-GONE™ is not recommended for BU coins. I&#039;ve found that the unoxidized copper surface of BU coins can become dull after use. When copper oxidizes, it actually produces a protective layer on the surface. VERDI-GONE™ is specifically designed to exploit that characteristic. It tends to only react with verdigris (acetates, carbonates, sulfates and chlorides of copper).</p><p>&nbsp;</p><p>- After removing verdigris with VERDI-GONE™, some of the non-oxidized copper surface may be exposed creating some uneven color. In those cases I recommend reoxidizing the surface by exposure to air for a few days, weeks or even months. Doing so will allow the copper to reoxidize, smoothing the color of the coin.[/QUOTE]</p><p><br /></p>
