Let the stove cool.
Wipe up all of the food residue from the cooktop with a damp sponge.
Flip the sponge over to use the abrasive side to work off any burnt residue. Press hard and scrub the burnt residue off. You may not be able to remove all of the stain this way.
Hold a razor at a 45-degree angle with the stove top and slide it across the burn residue to remove the rest of it. Make sure the stove top is wet the entire time, as the water will lubricate the surface to avoid scratches.
Add just enough water to 1 cup baking soda to make a thick paste.
Spread the paste over the burn pan marks and let it sit for 10 minutes.
Pour 1 tablespoon white vinegar over the baking soda paste and watch the two fizz for several minutes. This will help loosen the stains.
Scrub the baking soda into the stove top until all of the stains are gone.
Rinse the area with clear water and dry it completely.
