No cook enjoys cleaning pots in which food has been scorched or burned. Prevention is the best medicine, but if it happens to you, there are ways to make the job a little easier.
Try vinegar and baking soda
Sprinkle baking soda in the bottom of the pan, and add to it a solution of half vinegar and half water. Make sure it is enough to cover the bottom of the pot and whatever has been burned onto it. Place the pot over heat and boil the liquid for 20 minutes. Remove the pot from the heat and run water through it to loosen the burned food. Use baking soda and a non-metallic scrubbing pad to remove any remaining food or stains. Rinse with clean water and dry thoroughly.
Try club soda
If the previous method was not successful, pour club soda into the pot while the pot is still warm. This allows the bubbles in the club soda to loosen the burned food.
If the pot still has burned food in it, put it in the freezer for a couple of hours before scrubbing. This will render the food more dry and brittle, making it easy to remove.
Try dishwashing soap and water
If the previous methods do not work, squirt dishwashing soap into the pot and add enough water to cover the burned areas. Let it sit for an hour and then boil the liquid in the pot for 10 to 15 minutes. After the water has cooled to a safe temperature, use a non-metallic scrubbing pad to remove any remaining food or stains. Rinse with clean water and dry.
Remove stubborn stains with vinegar or denture tablets
If the stained pot is stainless steel, soak it in vinegar for 30 minutes. Follow up with a rinse in hot soapy water and a second rinse in cold water; dry carefully. If the pot has an enameled surface, fill the pot with warm water and drop in a denture tablet. When the fizzing stops, the pot should be clean; rinse with water and dry.
