Add a mild dishwashing soap to warm water in the kitchen sink. Scrub on the stain with a washcloth. Dry the cookware off with a towel to prevent water spots.
Place the cookware onto the stove top if the burn stain remains. Cover the burned area with vinegar and add an equal amount of water to the cookware.
Pour 1 tablespoon of baking soda into the water. Stir the diluted vinegar until the baking soda dissolves completely.
Bring the solution to a boil for five to 10 minutes. Scrape on the burned area with a wooden spoon until you loosen it.
Remove the stainless steel pan from the stove top. Pour the hot liquid into the sink.
Sprinkle baking soda over the steel pan. Scrub on the surface with a nonabrasive sponge.
Rinse the cookware with clean water. Dry the surface with a towel to remove the excess water.
