Clean your Tramontina correctly to maintain it. Fill the kitchen sink with 2 inches of warm water. Put on a pair of rubber gloves.
Place the first Tramontina piece in the water. Sprinkle the inside surface with nonabrasive, bleach-free cleansing powder.
Tip the pot or pan to add a small bit of water from the sink to the inside. Use just enough water to form a paste with the powder. Rub the paste over the inside of the Tramontina piece in a circular motion, using a soft rag.
Rinse the piece well with plain water and set it on a towel to air-dry. Wash the rest of your Tramontina pieces in the same fashion.
Keep stainless steel pieces clean and dry. If you have cast iron pieces, oil and season them regularly with a food-grade oil just as you would any cast iron.
