How to clean a cast iron skillet without damaging it
How do you clean a cast iron skillet after cooking? The routine is simple: remove food debris, hand wash, dry completely, and apply a very thin layer of oil when necessary. Specific care may vary depending on the manufacturer and type of pan.
The basic rule: wash, dry, and protect
Cast iron can rust if it remains damp, so it is important not to leave the pan soaking or store it wet. For routine cleaning, you can use warm water and, when the manufacturer allows it, a small amount of soap.
How to clean a cast iron skillet step by step
- Let it cool down. Avoid sudden thermal changes and do not pour cold water onto an extremely hot pan.
- Remove food residue. Use a suitable spatula, scraper, or brush. If there is stubborn stuck-on food, you can add a little water and heat it gently for a few minutes to make it easier to remove.
- Wash the skillet by hand. Use warm water and, if the manufacturer allows it, a small amount of dish soap.
- Rinse well. Do not leave any food or soap residue on the surface.
- Dry it completely. Use a clean cloth or paper towel. If necessary, you can place it on low heat for a few minutes to remove any remaining moisture.
- Apply a very thin layer of oil. Spread it over the surface and wipe off the excess. There should not be a thick or sticky layer left.
Can you wash a cast iron skillet with soap?
Yes, in general. The traditional advice to always avoid soap is not a universal rule. Current cast iron manufacturers indicate that warm, soapy water can be used for routine cleaning.
If your manufacturer provides different specific instructions, follow those guidelines.
Can it be left to soak?
It is not recommended to leave a cast iron skillet in water for a long time. Prolonged moisture increases the risk of rust. For tough residue, it is better to use a scraper or brush and, if necessary, briefly heat a little water in the pan to help loosen it.
How to clean stuck-on food residue
If food has stuck to the pan, avoid starting with harsh products. First, remove the residue with a suitable spatula or scraper. You can also partially cover the area with water and heat it gently for a few minutes to facilitate removal.
Afterward, wash, rinse, and dry the skillet completely. If you use a scouring pad, choose one suitable for cast iron and use it sparingly.
How to prevent the skillet from rusting
- Do not leave it in the sink full of water.
- Do not put it in the dishwasher.
- Dry it completely after washing.
- Store it in a dry place.
- Apply a very thin film of oil when necessary.
Is it necessary to oil it after every wash?
A very thin layer can help protect the surface, especially after washing and drying the pan. There is no need to leave a visible amount of oil: spread it out and remove the excess with paper or a cloth.
What to do if rust appears?
A small rusted area does not necessarily mean the pan is ruined. Rust can be removed through proper treatment and, if part of the seasoning has been removed, it may be necessary to re-condition the pan following the manufacturer's instructions.
What product to use
For daily cleaning, use a product compatible with the manufacturer's directions. If you use our Nº400 Dish Soap, follow the product instructions and rinse the pan well afterward.
Mistakes to avoid
- Leaving the skillet submerged for hours.
- Storing it while damp.
- Putting it in the dishwasher.
- Applying an excessive layer of oil.
- Using harsh products without checking the manufacturer's directions.
- Causing sudden temperature changes.
