Why Cleaning a Cast Iron Skillet the Right Way Matters
A cast iron skillet isn’t just a cooking tool it’s an investment. The surface develops a natural nonstick layer called seasoning. This layer improves over time if you treat it correctly. Using the wrong cleaning methods (like harsh soap or soaking it in water) can ruin the seasoning and cause rust.
That’s why learning how to clean a cast iron skillet properly ensures that your cookware performs perfectly every time whether you’re searing a steak or baking cornbread.
What You’ll Need Before Cleaning
Before we get into how to clean a cast iron skillet, gather a few simple items you probably already have:
- Hot water (no soap or mild only)
- A stiff brush or non-metal scrubber
- Coarse salt (for tougher residue)
- Paper towels or a clean cloth
- Cooking oil (vegetable oil or flaxseed oil)
These items make the cleaning process quick, safe, and effective.
Step-by-Step: How to Clean a Cast Iron Skillet
Now, let’s break down how to clean a cast iron skillet in easy steps.
Step 1: Clean While It’s Still Warm
After cooking, let your skillet cool slightly not completely. Warm pans clean better because the residue comes off easily. Pour off excess grease but leave a thin oil layer to protect the surface.
Step 2: Rinse with Hot Water
Rinse the skillet under hot running water. If food bits are stuck, scrub gently using a brush or sponge. Avoid steel wool or dish soap if possible.

Step 3: Dry Thoroughly
Drying is the most crucial step in how to clean a cast iron skillet. Moisture is the enemy of cast iron. Wipe with a towel, then place it on a stove burner over low heat for a few minutes to evaporate any hidden moisture.
Step 4: Re-Season After Each Use
Once your skillet is dry, apply a light layer of oil (about a teaspoon). Rub it in with a paper towel until the surface looks shiny but not greasy. This keeps your skillet seasoned and rust-free.
