Cindy Olsen asked about copper & brass polishes, and some recommendations have been made to her. One should also consider applying a protective coating after polishing, to reduce the amount of re-tarnishing. This will then save you much time in re-polishing, and also reduces the wear on the objects. I don't know what products you have available in the USA, but in Australia we tend to use micro crystalline wax, Incralac (acrylic lacquer with BTA inhibitor added), Frigilene or Ercaline.
