Thanks to Jonathan's tip, most of us now know that we can clean cast iron pots with kosher salt. Did you know that if you add half a lemon to that mix you can also clean and shine your copper pots?
Now, we don't own any copper pots -- but we just happened upon this little how-to over at Natural Home magazine, and we'll take their word for it.
All you need to do is dip the cut half of a lemon in a dish of kosher salt, get an 1/8 inch of crust on the lemon, then scrub away at your copper pots in a circular motion -- adding more salt as needed.
