Every hobbyist and homeowner seems to have their own favorite metal polish/tarnish remover.  After using many products over many years, Maas Metal Polish is my favorite.  First of all, it works with the least amount of effort. I am not saying NO effort, but the least amount of effort.  It is less messy than many others and less pungent.  Two ounces will set you back less than five bucks, and one tube lasts a long time.  Literally, “a dab will do ya” in most cases.  Please note this is NOT intended for brushed aluminum.
