5 Cast Iron Cleaning Mistakes to Avoid (and What to Do Instead)

Keeping cast iron in good shape isn’t difficult, but the wrong habits can ruin even the best pan. Here are the most common cast iron cleaning mistakes—and how to avoid them so your cookware lasts for generations.

Mistake #1: Using Dish Soap

Dish soap may be fine for stainless steel, but not for cast iron. Soap breaks down the protective seasoning layer that makes your pan nonstick. Instead of dish soap, use a natural cast iron scrub like salt and baking soda to clean safely.

Mistake #2: Letting Cast Iron Soak

Leaving cast iron in a sink of water is a recipe for rust. Even a short soak can cause orange spots to form. Always wash quickly, rinse, and dry thoroughly.

Mistake #3: Air-Drying the Pan

One of the most common cast iron cleaning mistakes is leaving the pan to dry on its own. Cast iron needs to be dried completely with a towel or over low heat to keep rust away.

Mistake #4: Skipping the Oil Step

After cleaning, cast iron should always get a light coat of oil. This seals the surface, protects against moisture, and keeps your seasoning strong. Forgetting this step shortens the life of your pan.

Mistake #5: Using Steel Wool

Abrasive steel wool can strip seasoning and scratch the surface. Save it for extreme rust removal only. For daily cleaning, natural scrubs and soft brushes are enough.

How to Clean Cast Iron the Right Way

To avoid these mistakes, follow this simple routine:

1. Rinse the pan with warm water after use.
2. Scrub gently with salt and baking soda to lift food residue.
3. Rinse again and dry completely with heat or a towel.
4. Apply a thin coat of oil before storing.

Final Thoughts

By avoiding common cast iron cleaning mistakes, you’ll preserve your cookware’s seasoning and performance. With the right habits, your skillet can outlast every other piece in your kitchen.

Frequently Asked Questions

Can I ever use steel wool on cast iron?
Only for severe rust. For daily cleaning, use natural scrubs or soft brushes to protect seasoning.

What happens if I forget to oil my pan?
It won’t be ruined right away, but repeated neglect can cause the seasoning to weaken and lead to rust.

Is it okay to use soap once in a while?
Occasional use won’t destroy a pan instantly, but over time, it breaks down seasoning. It’s best avoided altogether.
