The best way to "clean" common cents is to just hold them under hot running water and rub them with your fingers. It works great for removing general grime and it's pretty safe on the surfaces.
BadThad: You shocked me with that one. You obviously forget that some people have excessively hard water, many tap waters contain Chlorine, some people have water softeners, etc. That hot running water could also contain amounts of almost anything on or in Earth. Also, you may not have met or known people that worked with their hands alot and their fingers are like a grinding wheel.
Really not a good suggestion.
