Cast iron skillets are indispensable in the kitchen thanks to their high heat resistance, even heat distribution, and naturally developing non-stick surface over the years. With proper use and regular care, cast iron grill pans and frying pans can last for generations. However, two essential questions are commonly asked:
“How do you clean a cast iron skillet?”
and
“Can a cast iron skillet go in the dishwasher?”
In this comprehensive guide, we explain cast iron skillet cleaning methods, daily care routines, proper drying techniques, and long-lasting maintenance tips step by step.

A cast iron skillet is not like ordinary steel or Teflon pans; its surface is coated with a natural layer of oil called seasoning. This layer ensures a non-stick finish and acts as a protective barrier that prevents rust.
Therefore, proper cast iron skillet cleaning must:
Be done using the correct methods,
Avoid chemicals that can damage the seasoning layer,
Include maintenance after every wash.
Using incorrect cleaning methods can damage the seasoning layer, causing the surface to appear dull, lose its non-stick ability, or eventually rust.
Cleaning a cast iron skillet is actually very simple; the key is following the right method. Below are all techniques for both daily cleaning and deep maintenance.
Cleaning your cast iron skillet immediately after each use is the best way to protect its surface.
Rinse the skillet with hot water while it is still warm.
Oil and food residues dissolve more easily when the pan is warm.
Use a non-metal brush or firm sponge.
Metal scrubbers are not recommended because they can damage the seasoning layer.
About using soap:
Modern cast iron skillets can tolerate mild soap.
Just avoid excessive chemical use. A small amount of soap will not harm the seasoning.
Rinse thoroughly and dry with a towel.
Place the skillet on the stove for 1 minute to evaporate remaining moisture.
Apply a thin layer of cooking oil (sunflower, canola, or olive oil).
This step strengthens the seasoning layer and prevents rust.
That’s it! Regular daily cleaning is the most effective way to extend the life of your cast iron skillet.
Sometimes, foods like meat, fish, or eggs may leave stubborn residues on the surface.
Sprinkle a handful of coarse salt into the skillet.
Add a few drops of water.
Scrub with a wooden spatula or a firm sponge.
Salt acts as a natural abrasive, removing residue without damaging the surface.
Rinse, dry, and oil the skillet.
This method, known as the salt scrub, is one of the safest ways to clean a cast iron skillet.
Deep cleaning is necessary if:
Rust has begun to form,
The surface appears dull,
Food sticks frequently,
The seasoning layer has worn down.
Wash the skillet with warm water.
If needed, use a small amount of soap.
Rinse thoroughly and dry completely.
Apply a thin layer of oil over the entire surface.
Preheat the oven to 180–200°C (350–400°F).
Place the skillet upside down in the oven.
Bake for 1 hour to rebuild the seasoning layer.
Turn off the oven and let the skillet cool inside.
After this process, your cast iron skillet will regain its original performance.
This is one of the most frequently asked questions.
The short and clear answer is:
No, a cast iron skillet should never be put in the dishwasher.
Dishwashers expose the skillet to prolonged high heat, water, and harsh detergents.
This completely strips the seasoning layer.
The skillet becomes unprotected and rusts quickly.
Cast iron can absorb water, causing damage during the drying process.
Dishwasher detergents are not suitable for cast iron surfaces.
If you want your cast iron skillet to last for decades, never place it in the dishwasher.
Cast iron is durable, but incorrect cleaning habits can cause lasting damage. Avoid:
Damages the seasoning layer and causes rust.
Though it seems harmless, long exposure to water will inevitably cause rust.
These can scratch the surface and strip the seasoning layer.
Moisture is cast iron’s greatest enemy.
Moisture = Rust.
If you prefer chemical-free cleaning, try these practical alternatives:
Safely removes stuck-on food naturally.
Ideal for eliminating strong odors.
A natural purifier—but should be used sparingly.
With proper care, a cast iron skillet can last a lifetime — or even be passed down through generations.
Applying a thin layer of oil after each use strengthens the seasoning daily.
This can cause the skillet to crack.
Acid weakens the seasoning layer.
This fully prevents rust formation.
Yes. Mild soap will not damage the seasoning on modern cast iron skillets.
Perform deep cleaning + re-seasoning to restore it.
This indicates that the seasoning layer is building and strengthening.
With proper care, cast iron does not wear out — in fact, it gets better with age.
Properly cleaned and regularly maintained cast iron skillets are not just cookware—they are a culinary legacy that can be handed down for generations.
To summarize:
Cast iron skillet cleaning is simple, practical, and chemical-free.
They should never be placed in the dishwasher.
They must be dried and lightly oiled after every wash.
Regular seasoning improves performance year after year.
By following this guide, you can keep your cast iron skillet in top condition and enjoy perfect cooking results with every recipe.
