In one sentence, describe what the following article is about:

If you want to remove burn marks from the bottom of your Circulon pans, use baking soda. While you don’t have to use a particular amount, you want the bottom of your pan to be completely covered. You can pour the baking soda straight from the box, or you can use a spoon and shake it over top of your pan. Fill up a measuring spoon with vinegar, then pour it over the baking soda. The bubbling or fizzing that occurs when you mix the two helps lift up the burnt marks from the surface of your pan. It’s okay if all of the baking soda is not mixed with vinegar. You will distribute the vinegar as you scrub the pan. Move your fingers in small, circular motions to get rid of the burnt areas. Continue scrubbing until you are satisfied with the look of the pan. Be aware that not all of the marks will come off if your pan is  excessively burnt. If you don’t have gloves, you can use a folded up paper towel instead. Fold it in half or in fourths, then rub the paper towel in circular motions over the bottom of your pan. After you’ve cleaned the bottom, place your pan under warm, running water to get rid of any remaining baking soda or vinegar. Squeeze a little bit of soap onto a soft nylon brush, and gently scrub over the surface of your pan. Then, rinse your pan a final time to remove the soap. Wipe the bottom of your pan with a clean kitchen towel. The bottom of your pan should be free of dark, burnt areas.

Summary:
Dump a thin, even layer of baking soda across the bottom of your pan. Pour about 1 US tbsp (15 mL) of white vinegar over the baking soda. Put on rubber gloves and scrub the bottom of the pan with your fingers. Rinse off the baking soda with warm water. Wash your pan with soapy water.
