Depends on what you want to remove. Water and soap will do no harm and dissolve mud and fat. For chemicals, try acetone. Don't try to remove oxide.

An unidentified coin is a piece of metal. An identified coin is a piece of history.

About removing oxidation, remember that what's left is going to look like a cheap new copy.   Old corrosion in lead and pewter coins is difficult to fake.   Only if you are conserving pieces which cannot be read at all, or are fused together, should mild acid be used to dissolve carbonate.   Dilute acetic or HCl to start.
