Fill the pot with enough water to cover the burnt area
Add 1 to 2 tablespoons of baking soda
Bring the mixture to a gentle boil
Turn off the heat and let it soak for 15 to 30 minutes
Scrub the bottom with a non-abrasive sponge or brush
For stubborn spots, make a paste of baking soda and water
Apply the paste to the burnt areas and let it sit for 15 minutes
Scrub again and rinse thoroughly
If needed, add a small amount of vinegar after the baking soda soak
Wipe clean with a soft cloth
Repeat the process if the burn marks remain
