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