Unless you are an expert restorer, the short answers are NO, NEVER, NOT EVER, DON'T EVEN THINK ABOUT IT!
If you have a particularly dirty coin you might be able to remove some of the surface crud using a soft cloth and distilled water but you should never use any chemicals or abrasives. Home-brew cleaners (e.g. Tarn-X, lemon juice, dish detergent, etc.) may make a coin look better temporarily but will damage its surface in a way that will leave it open to more damage later.
Professional restorers have the knowledge and tools needed to remove things like scale and other crud from a coin's surface without harming it, but in many cases it's safer to simply do nothing to a dirty coin.
