How to get rust off of cast iron frying pans
Hi Sharon, I've found the best way to remove the rust and other built up gunk is to use steel wool pads to scrub the pans thoroughly. I like the ones that have the soap included in them. Scrub and sour the pans until the area returns to raw cast iron. Lots of elbow grease and a messy job. Then wash with warm soapy water and dry well with paper towels. To season the pans, use some vegetable oil on a paper towel and rub lightly over the pans and then place in an oven and back for 1/2 hour at 325-350 degrees. No more rust and your pans are ready to cook in again.
Here are some tips for cast iron skillets: https://www.craftylittlegnome.com/clean-season-cast-iron-skillet/
You can drizzle oil on the pan, pour some salt on it and then cut a potato in half and use the potato to scrub the rust off. Then re-season the pan.
You'll have to clean it and reseason it.
