- Neglect: Leaving your cast iron pan unseasoned or not properly maintaining it can increase the likelihood of rust.
Restoring a Rusty Cast Iron Pan
If your cast iron pan has already developed rust, don’t despair. Here are the steps you can take to restore it:
- Remove Loose Rust: Scrub away any loose rust using a stiff brush or steel wool. Avoid using abrasive pads or cleaners, as they can damage the pan’s surface.
- Create a Paste: Mix white vinegar and baking soda to form a thick paste.
- Apply the Paste: Apply the paste to the rusty areas and let it sit for several hours or overnight.

- Season the Pan: Re-season your cast iron pan to create a protective layer that will prevent future rust.
Preventing Rust on Cast Iron Pans
