<p>[QUOTE="Kentucky, post: 3630138, member: 33176"]See, here is where it gets icky... Many new collectors like to clean cents with an eraser and some have indignately posted here that it does no damage. Try looking at these with a 10x lens and a light that you can move around to see the multitude of scratches that have happened. If you can't tell if a coin has been cleaned, IT HASN'T BEEN CLEANED! </p><p><br /></p><p>Now, with that being said, what cleaning is acceptable and what is not. The most unacceptable practice is rubbing a coin. No matter how soft the cloth you use, if you are scrubbing grit around the surface, how can you not harm it? Rinsing and dipping are in most cases acceptable. Pure solvents should not harm the surface. The most common are water, acetone and xylene. Others are also acceptable but less often encountered, such as hexane, toluene, ethyl alcohol and isopropyl alcohol.</p><p><br /></p><p>Finally there is dipping in tarnish removers which has to be done with care and takes practice.[/QUOTE]</p><p><br /></p>
