How to Clean a Cast Iron Skillet (Everyday Method)
What You’ll Need:
- Hot water (no soap!)
- A stiff-bristle brush, non-metal scrubber, or chainmail scrubber
- Kosher salt (for stuck-on food)
- Clean paper towels or cloth
- Neutral oil (like canola, vegetable, or flaxseed)
Step 1: Rinse Right After Cooking
While the skillet is still warm (but not scalding), rinse it under hot water. This helps remove any leftover food without letting it dry or stick.
❌ Don’t use soap. It breaks down the seasoning layer.
Step 2: Scrub Gently (Or Use Salt for Stuck-On Mess)
Use a brush or scrubber to remove food bits. If anything’s stuck, sprinkle kosher salt into the pan and scrub it around with a damp cloth. The salt acts as a natural, non-toxic abrasive.
Step 3: Dry It Completely
Wipe the pan dry with a towel, then place it over a low flame for 1–2 minutes to evaporate any lingering moisture.
Even a tiny amount of moisture can cause rust.
Step 4: Re-Oil and Store
Apply a thin layer of oil to the inside of the pan using a paper towel. Buff it in well so the surface doesn’t feel sticky. This keeps the seasoning intact and prevents rust between uses.
Dealing with Rust or Damaged Seasoning?
If your skillet is rusty or sticky, it might need a full re-seasoning:
- Scrub off rust with steel wool.
- Wash, dry, and apply a thin coat of oil.
- Bake upside down at 450°F (230°C) for 1 hour.
- Let it cool in the oven.
Bonus Tip: What Not to Do When Cleaning a Cast Iron Skillet
- Don’t use soap — it strips the seasoning.
- Don’t soak it in water. Rust will form fast.
- Don’t air dry. Moisture = your skillet’s enemy.
- Don’t use steel wool every time. That’s for re-seasoning only.
Why Cast Iron Is Worth the Extra Effort
A well-maintained cast iron skillet becomes more non-stick over time, retains heat beautifully, and adds rich flavour to your food. Best of all? It’s chemical-free, unlike many synthetic-coated nonstick pans.
“Cast iron takes care of you when you take care of it,” says one home cook on Reddit’s r/CastIron.
