When cooking as we try to be carefully the food burnt sometime steel vessels can happen to anyone.
Remove the steel vessel from the burner as soon as you smell burning and plunge the bottom into water. This will stop the burning action and, if you catch it early enough, stop the burnt taste from being transferred to the food.
Wash your burnt steel vessel immediately after cooking so foods don’t have time to harden onto the surface and get stuck.
Soak a burnt steel vessel in an equal solution of baking soda and warm water. Use just enough to cover the burned area. The stain should lift off in about 20 minutes.
Boil the steel vessel in a baking soda and water mixture to remove any burnt steel vessel. Add 1 tsp. baking soda for each cup of water (1 to 2 cups of water should be enough) and gently boil for about 20 minutes, or until you see the food floating free. Don’t walk away and allow water to boil off. Wash in warm sudsy water with a nylon scrubbing pad or brush, and dry thoroughly.
Use vessel cleaning paste or soap or powder and rub in a circular motion with scrubber until the stains disappear and shiny surfaces gleam as safe for cleaning every type of vessels. Never use abrasive cleansers, abrasive sponges or steel wool on your stainless steel as it may scratch the finish.
Rinse with clean water and dry thoroughly with a soft towel.
Never leave stainless steel vessels on a high heat burner for an extended period of time as it may cause discoloration that cannot be removed. Similarly, never leave boiling water to evaporate completely in a stainless steel vessels as it may cause permanent staining.
