Remove Rust from Cast Iron: The Aluminum Foil Trick

Cast iron cookware is known for its durability and heat retention, but maintaining it can be tricky, especially when rust appears. A popular and surprisingly effective cleaning method uses aluminum foil. This technique, endorsed by experts at the BBC, is praised for its simplicity and low cost. The key is using the aluminum’s rough texture, acting as a gentle abrasive, to remove rust without damaging the pan’s surface. Unlike harsh metal scrubbers or abrasive cleaners, aluminum foil safely removes rust while preserving the integrity of the cast iron. To implement this method, simply clean the pan with warm water and mild soap, then scrub the rusted areas with a ball of aluminum foil. Rinse the pan, dry it thoroughly, and apply a light coat of vegetable oil for protection against future rust. This process, known as seasoning, creates a protective layer that keeps your cast iron pan in tip-top shape.
