Random title: Cleaning
Explanation: Refers to removing dirt or otherwise altering the appearance of a coin through the use of chemical or abrasive materials that damage or scratch the surface in a detectable fashion. Cleaning is different than whizzing or mechanical alteration of the surface. A gentle cleaning in water or solvent that leaves no marks or residue is usually not considered harmful. Cleaning by either mechanical or chemical means that are detectable will generally result in lowering the grade and value of a coin
