<p>[QUOTE=&quot;GDJMSP, post: 291526, member: 112&quot;]Typically harsh cleaning would be defined as any time the surface of the coin is touched with anything during the cleaning process. </p><p><br /></p><p>Dipping has always been an acceptable form of cleaning to many because it is strictly chemical in nature - in other words the surface of the coin is not ever touched or rubbed with anything. However, dipping can be considered as harsh as well if it is over-done since the acid in the coin dip has the ability to literally eat away the surface of the coin.</p><p><br /></p><p>Ultra-sonic cleaning would be much like dipping, it could go either way. Do it just right and no marks will be left, do it wrong or too long and the surface of the coin can be destroyed.</p><p><br /></p><p>So in a nutshell, any of these methods can be considered as harsh cleaning - it is a matter of degree.</p><p><br /></p><p>Whizzing is not cleaning at all - that is out and out alteration in order to deceive.[/QUOTE]</p><p><br /></p>
