How To Restore Your Cast-Iron Skillet:
RUST ON YOUR CAST IRON?
Cast iron rusts easily when not dried properly or when exposed to humidity. You can prevent rust on your cookware by always drying it thoroughly and promptly (no air drying!), storing it in a dry place, and making sure never to soak it in water or put it in a dishwasher.
If rust does form (it happens to the best of us!), carefully remove by scrubbing the affected area with kosher salt and steel wool. Then clean the cookware as you do after every use.
If your cookware keeps getting rusty, splotchy, or has sticky residue that refuses to come off, it’s time to reseason!
HOW TO RESEASON
1. Scrub the entire exterior of the pan with kosher salt and steel wool.
2. Clean the cookware as you do after every use.
3. Follow the 1-2-3 SEASON steps here -- and restore your cookware to its original luster.
