Copper verdigris is beautiful on rooftops, but the corroded metal doesn't look so good on your pots and pans. So it's important to keep them polished and in shipshape. As it turns out, it's not so difficult to do so. First, cut a lemon in half. Then, make like you're whipping up a margarita and dip the exposed face of the lemon into a plate of course grind salt (like sea salt). Take the salted lemon and apply it to your copper, giving it a good, hard grooming. Your pots and pans should shine like the top of the Chrysler building in no time! If you happen to make yourself a margarita while you're at it, don't worry: I won't tell anyone.
