To get rid of the mold smell on ceramic or enameled cast iron cookware, follow these steps:
Wash the cookware: Start by thoroughly washing the cookware with hot water and mild dish soap. This will help remove any visible mold or mildew from the surface.
Vinegar solution: Create a solution of equal parts white vinegar and water. Fill the cookware with the solution, ensuring it covers the areas affected by the mold smell. Let it sit for about 15-30 minutes. Vinegar is effective at killing mold and neutralizing odors.
Baking soda scrub: After the vinegar soak, drain the solution and sprinkle baking soda inside the cookware. Use a sponge or soft brush to scrub the surface gently. Baking soda is a natural deodorizer and will help remove any lingering smells.
Sun-drying: Allow the cookware to dry in direct sunlight, if possible. Sunlight has natural disinfecting properties and can further help eliminate mold and mildew odors.
Bleach solution (if needed): If the mold smell persists, you can use a diluted bleach solution as a last resort. Mix one tablespoon of bleach with one gallon of water. Fill the cookware with the solution, and let it sit for a short time (about 5-10 minutes). Then, thoroughly rinse and wash the cookware with hot water and dish soap to remove any traces of bleach.
Baking soda paste (for enameled cast iron): For enameled cast iron, you can also make a paste using baking soda and water. Apply the paste to any stained or odorous areas, and let it sit for a few minutes before gently scrubbing and rinsing.
Re-season (for bare cast iron): If the cookware is bare cast iron and you had to resort to using bleach, you will need to re-season it. Coat the inside with a thin layer of cooking oil and heat it in the oven at a high temperature for about an hour. This process will help create a new protective layer and prevent rusting.
Remember, prevention is essential to avoid mold growth in the future. Always ensure your cookware is thoroughly dried before storing it, and keep it in a dry, well-ventilated area. Additionally, avoid leaving food residues in the cookware, as they can promote mold growth. Regularly inspect your cookware for signs of mold or mildew and address the issue promptly if it arises.
