Have you ever cleaned your cast iron skillet and then noticed the seasoning was gone? That used to happen to me too. I love cooking in cast iron, but I did not know the right way to clean it. The seasoning is what makes cast iron non-stick and full of flavor. In this article, I will show you exactly how to clean cast iron without removing seasoning. You will keep it strong, smooth, and ready for your next meal.
Let It Cool Before Cleaning
Right after cooking, your cast iron will be hot. Do not clean it while it is still hot. Let it cool down first. This is very important. If you put cold water on a hot pan, it can crack. Yes, even cast iron can crack when the temperature changes too fast. That is called thermal shock. So give it a few minutes to cool off.
Once the pan is warm (not hot), you can move on to cleaning. At this point, most food stuck to the pan will be soft and easier to remove. Trying to clean right away may damage the seasoning. So patience is your friend.
Letting the pan cool also helps you hold it better. You do not want to burn your hands. Some people try using gloves or towels to grab it, but I find it safer to just wait. When the pan is warm and safe to touch, you’re ready for the next step.
Waiting a few minutes will save your pan and protect the layer of seasoning. It also helps you do a better job cleaning it because the mess will not be stuck hard like it gets when it fully dries.
- Let the pan cool after cooking
- Avoid pouring cold water on a hot pan
- Warm pans are easier and safer to clean
- Cooling protects the seasoning layer
- Never rush this part
Use Warm Water and a Soft Scrubber
When your cast iron is cool and ready, you should clean it using warm water and a soft scrubber. No soap. Soap can break down the seasoning. That is the number one thing you want to avoid. I know, we are used to using soap to clean dishes, but cast iron is different.
Run warm water into the pan and grab a soft sponge, dishcloth, or brush made for cast iron. There are even special cast iron scrubbers you can buy that won't hurt the seasoning. Avoid using steel wool or anything sharp. That can scrape off the seasoning that took you a long time to build.
If something is stuck on the surface, try scrubbing gently in circles. If it won't come off, you can use a little bit of coarse salt. Pour some salt into the pan, add a few drops of water, and rub gently. Salt acts like a gentle cleaner without hurting the pan.
Some people use chainmail scrubbers. These are safe for cast iron if used gently. But you don't need anything fancy. A sponge or soft brush with warm water is usually enough.
- Use warm water only
- Do not use soap or harsh cleaners
- Use a soft sponge, cloth, or cast iron brush
- For stuck food, try salt and water paste
- Scrub in circles, not too hard
Dry It Completely Right After Washing
After you rinse and scrub your cast iron, do not let it sit wet. Cast iron rusts very fast. Even a little water left on it can cause rust. You need to dry it right away, and you need to dry it well.
First, use a clean towel or paper towels to wipe off all the water. Make sure you reach the edges, handle, and even the bottom of the pan. Every drop matters.
Then, put the pan on the stove over low heat. Let it warm up for a few minutes. This helps remove any water that you may not see. The heat will dry out the pores of the metal and keep it rust-free.
After the pan is warm and fully dry, turn off the heat. Let it cool down a little before you put it away. This is also a good time to add a little oil (which we will talk about in the next section).
Drying is one of the most important parts of cleaning cast iron. If you skip this step, the seasoning will not last, and rust will appear quickly.
- Wipe off water right away
- Dry the whole pan, even the edges and bottom
- Heat it on the stove to remove hidden water
- Never store cast iron while it is wet
- A dry pan stays seasoned and rust-free
Rub a Thin Layer of Oil
After your pan is dry and still warm from the stove, you should rub a thin layer of oil on it. This helps protect the seasoning and makes your next cooking even better. The oil fills the tiny pores in the metal and keeps it smooth and non-stick.
Use a cooking oil that has a high smoke point. Good options are flaxseed oil, canola oil, or vegetable oil. Just pour a few drops onto a paper towel and rub it around the inside and outside of the pan. You do not need a lot. Less is better. Too much oil can become sticky.
Once the oil is rubbed in, you can either leave the pan as it is, or you can heat it for a few more minutes on the stove. Heating helps the oil soak into the metal and makes the seasoning stronger. But if your pan already has good seasoning, just a light coat is enough.
Always store your pan with this oil layer. It will stop rust and keep the surface smooth. If you skip oiling, the seasoning can slowly fade.
- Use just a few drops of oil
- Rub the whole surface, inside and outside
- Choose oils with high smoke points
- Heat it for stronger seasoning (optional)
- Oiling keeps your pan protected and ready
Store It the Right Way
Now that your cast iron is clean, dry, and oiled, it is time to store it. How you store your pan matters. If you put it in a place with moisture or cover it too tightly, it can still rust.
First, keep it in a dry spot. Do not store it under the sink or in a damp cabinet. Air should be able to move around it. If you are stacking other pans on top, put a paper towel between them. This stops scratches and soaks up any leftover moisture.
Do not use plastic lids or covers that seal in air. A light cloth or paper towel is better. It lets the pan breathe and stay dry.
If you are storing it in the oven (many people do), make sure the oven is not wet or holding steam. Also, remember to take it out before you turn on the oven to preheat. You don't want to burn the oil layer or damage the seasoning.
Proper storage is like the final step in keeping your pan perfect.
- Keep it in a dry place
- Avoid plastic lids or tight covers
- Use paper towels between stacked pans
- Let air move around it
- Never store near water or steam
Clean After Every Use Without Soap
The best way to keep your cast iron strong is to clean it after every use. Do not wait hours or days. The longer food sits, the harder it gets to clean, and the more damage it does.
Even if it looks clean, always rinse and wipe it after cooking. Small bits of food can build up and change the seasoning. But remember: no soap. Warm water and a scrubber are enough.
If you cook something very sticky or greasy, you can clean it the same way, just use salt if needed. After that, dry it and oil it again like we talked about.
This habit of cleaning right away helps your pan stay smooth, shiny, and ready to go. Your food will taste better, and you will spend less time fixing rust or seasoning later.
Cleaning after each use is not hard once you get used to it. It becomes a simple part of your cooking.
- Rinse right after cooking
- Clean even if the pan looks clean
- Use salt for sticky messes
- Always dry and oil after cleaning
- Make it a daily habit

Frequently Asked Questions (FAQs)
Is it okay to use water on cast iron?
Yes, it is okay to use water on cast iron as long as you do it the right way. Use warm water to clean it after it cools down. Do not soak it or leave it in water for a long time, because that can make it rust. After using water, always dry the pan completely and then rub it with oil. Water is safe when used quickly and with care.
Can I clean cast iron with soap just once?
It is best not to use soap at all, even one time. Soap breaks down the oil layer called seasoning that protects your pan. If you use soap, it may remove some of that seasoning and make your food stick next time. Even if the pan smells or has grease, warm water and salt can clean it. If you already used soap, just rinse well, dry, and apply oil again.
Do I need to season my pan every time?
You do not need to season your pan fully every time, but you should oil it lightly after each cleaning. This helps keep the seasoning strong. A full seasoning in the oven is only needed if the pan is losing its non-stick feel or has rust. Daily light oiling is enough to keep the surface protected and smooth.
Is it safe to use cast iron every day?
Yes, it is very safe and even healthy to use cast iron daily. It can last a lifetime if you take care of it. Cooking in cast iron may even add a little iron to your food, which is good for your health. Just be sure to clean it properly after each use, and your pan will be ready for cooking every day.
Can I use metal utensils on cast iron?
You can use metal utensils, but gently. Too much scraping or banging can scratch the seasoning. It's better to use wood or silicone tools to keep the surface smooth. If you do use metal, just be careful and avoid stabbing or digging into the pan. Scratches can be fixed, but it’s better to prevent them.
Do I need a special brush for cleaning?
You do not need a special brush, but a brush made for cast iron can help. Soft bristles or chainmail scrubbers are safe and work well. You can also use a regular sponge or cloth. The key is to avoid anything sharp or too rough. If it feels like it could scratch your pan, don't use it.
Is it okay to store cast iron in the oven?
Yes, storing cast iron in the oven is fine, as long as the oven is dry. Many people do this because it saves space. But remember to take it out before you turn the oven on to preheat. Also, keep the lid off or use a paper towel to let it breathe. This helps stop rust from forming.
Can I fix rust if it shows up?
Yes, you can fix rust on cast iron. First, scrub off the rust with steel wool or sandpaper until the surface is clean. Then wash and dry the pan. After that, apply a thin layer of oil and bake it in the oven at 450°F for one hour. This will bring back the seasoning. It takes time, but it's worth it. Your pan can be like new again.
