<p>[QUOTE="1865King, post: 5369676, member: 103207"]Any method that can alter the surface of the coin is cleaning. However, sometimes cleaning is required to save coin from further damage. Dipping removes tarnish which is done by stripping off some of the surface metal. Soaking in acetone, detergent or water is a form of cleaning. Then there is wiping, scrubbing and wire brush. Some of these methods are acceptable and others are not. When not done correctly the coin is given a details grade. Those that have been lightly cleaned are normally considered market acceptable and will normally be straight graded. A recently new terminology for a cleaned coin that has been applied is called Saltwater Affect. A silver coin in a slab that has been given a label stating saltwater affect is a play on words. That coin has been chemically cleaned to remove encrusted material on a silver or gold coin that was found in the ocean. The silver coins that have been processed in this method are generally looking like the coin was severely corroded.[/QUOTE]</p><p><br /></p>
