To remove rust from old cast-iron skillets and pans, you can follow these steps:
Scrub the Rust: Use a stiff brush or steel wool to scrub away the rust from the affected areas. Make sure to remove as much rust as possible to create a clean surface for the next steps.
Create a Paste: Mix equal parts of baking soda and water to create a paste. The paste should have a consistency similar to toothpaste.
Apply the Paste: Apply the baking soda paste to the rusted areas of the cast iron. Spread it evenly and ensure that all the rusted spots are covered.
Let it Sit: Allow the paste to sit on the cast iron for a couple of hours or overnight. This will give it time to work on the rust and help loosen it.
Scrub Again: After the paste has had time to work, scrub the cast iron again using a brush or steel wool. Focus on the rusted areas and continue scrubbing until the rust is removed.
Rinse and Dry: Rinse the cast iron thoroughly with water to remove any remaining paste or rust particles. Make sure to dry it completely to prevent any new rust from forming.
Season the Cast Iron: Once the rust is removed, it's crucial to season the cast iron to protect it from future rusting. Seasoning involves applying a thin layer of oil and baking the cast iron in the oven. This process helps create a protective, non-stick layer on the surface.
Regular Maintenance: To prevent rust from reoccurring, it's important to properly maintain your cast iron cookware. After each use, wash it with minimal soap, dry it thoroughly, and apply a light coat of oil to the surface.
Remember, removing rust from cast iron may require some effort, and severe rust or pitting may be difficult to completely eliminate. However, with proper care and maintenance, your cast iron cookware can be restored and enjoyed for years to come.
