Because it contains minerals, and those minerals will end up deposited on the coin.</p><p><br /></p><p>And no you most definitely do not want to use a toothbrush on a coin, or anything else for that matter. You never want to touch the surface of the coin with anything. There is no brush, fabric, cloth, Q-Tip, or even your fingers, that is soft enough to use to clean a coin. Anything you touch the surface of the coin with will leave behind traces (fine hairline scratches, or even not so fine scratches) of it having been touched.</p><p><br /></p><p>The only method of cleaning a coin that is acceptable is to soak or rinse the dirt &amp; grime off the coin. And there are only a few things you can use to soak or rinse the coin in - distilled water, acetone, &amp; xylene. </p><p><br /></p><p>Now as a general rule you don&#039;t want to use acetone on a copper coin. The only time you should use acetone on copper is when you are trying to remove PVC residue. It is best not to use it for anything else.</p><p><br /></p><p>Xylene should only be used when distilled water will not remove whatever is on the coin. Xylene is a solvent and it will remove oils and similar substances. But it should not be used for anything else.</p><p><br /></p><p>Distilled water is your best bet for ordinary dirt &amp; grime, and only distilled water. Do not use tap water, mineral water, soda water, or any other kind of water - just distilled water. You can buy it at the grocery store. And all you should do is put the coin in a small container of the water and let it soak. You don&#039;t want to rub the coin with your fingers, a brush, a cloth, or anything else. The most you can do is pick up the coin by the edges only and swish it back and forth in the distilled water. That&#039;s it, do nothing else. And if that doesn&#039;t take the dirt &amp; grime off the coin then leave the coin alone and accept it as it is.[/QUOTE]</p><p><br /></p>
