Last summer, I found a beat-up cast iron skillet at a neighborhood garage sale. It was covered in rust, and the seller sighed, āItās toastāthrow it away.ā But I decided to give it a try. After a little scrubbing, re-seasoning, and lots of use, that pan is now my go-to for crispy pancakes and seared steaks. So, is it true you have to toss a rusty cast iron? Letās break it down.
The Truth About Rusty Cast Iron š³
Rust on cast iron is just iron oxide, a surface layer that forms when iron reacts with water and oxygen. The good news? Itās removable. To save a rusty pan: Scrub the rust off with steel wool or a stiff brush, rinse with warm water, dry immediately (even heat it on the stove for a minute to ensure no moisture remains), then re-season it by coating with a thin layer of vegetable oil and baking at 350Ā°F for an hour. Your pan will be as good as new.
