How can I effectively polish my copper pots to restore their shine and luster?

To effectively polish copper pots and restore their shine and luster, create a paste using equal parts of salt, vinegar, and flour. Apply the paste to the copper surface and let it sit for about an hour. Then, scrub the paste off with a soft cloth or sponge. Rinse the pot with warm water and dry it thoroughly. Finally, buff the pot with a clean, dry cloth to bring out its shine.
