How to Clean Copper with Jewelry Polishing Cloth?

This only works effectively on sealed pieces as they don’t tarnish much. As sealed pieces simply tend to dull with time, a good buff with the polishing cloth can remove the dullness and make the copper gleam again. However, you can slow down the tarnish on even non-lacquered pieces by giving them a quick polish with a jewelry polishing cloth before and after you wear it to keep it shiny and minimize tarnishing.
