Cast Iron Care: The Ultimate Guide
Everything you need to know about seasoning, cleaning, and maintaining your cast iron cookware.
After five years of daily cast iron use and decades of watching how professionals maintain their pans, here's everything you need to know about keeping your cast iron in top condition.
Cast iron care is simpler than most people think. The key is understanding what seasoning actually is—a polymerized layer of oil that makes the surface naturally nonstick.
The Basics: Cleaning
Hot water and a stiff brush is all you need after most cooks. The heat from the pan helps the cleaning process.
Soap is actually fine. Modern soap won't strip your seasoning like the old lye-based soaps did. Use a small amount if needed.
Dry immediately. Water causes rust. Put the pan on a burner on low heat for a minute to evaporate all moisture.
Oil after cleaning. Add a small amount of oil and wipe it around—the thin layer maintains the seasoning.
Deep Cleaning (When Needed)
For stuck-on food, try these methods in order of intensity:
-
Kosher salt and water - Make a paste, scrub, rinse.
-
Chain mail scrubber - The Lodge chain mail at about $15 is perfect for stuck-on food.
-
Self-cleaning cycle - Put your oven on self-clean with the pan inside (extreme but effective).
Re-Seasoning
If your pan is rusted or has bare spots, re-season:
- Scrub with steel wool until bare metal
- Dry thoroughly
- Apply thin layer of oil (flaxseed is traditional, vegetable works)
- Bake upside down at 450°F for one hour
- Repeat if needed
Common Mistakes to Avoid
Don't soak in water - Rust happens fast.
Don't put in dishwasher - Will rust.
Don't use on glass cooktops - Can scratch, and heat transfer can crack glass.
Don't cook acidic foods in new pans - Tomatoes, citrus can strip new seasoning.
The Best Tools for Cast Iron Care
The Lodge Scrub Brush is what I use daily.
For re-seasoning, Flaxseed Oil creates the most durable seasoning.
A good cast iron conditioner makes maintenance easy.
Bottom Line
Cast iron is nearly indestructible. Clean it, dry it, oil it occasionally—that's it. Treat it well and it will last for generations.
