Each has different chemical characteristics, but act to dissolve organic material that has accumulated on the coin - without reacting to the metal. </p><p><br /></p><p>Dipping is different. It involves a reactive chemical that may damage the coin. The coin is dipped momentarily to remove tarnish or other non-organic material from the metal surface.</p><p><br /></p><p>Other respondents may explain this better, but there are many threads here about this subject.[/QUOTE]</p><p><br /></p>
