Simple Method for Cleaning Your Cast Iron Skillet
For everyday cleaning after cooking, you don’t need harsh chemicals or complicated procedures. Here’s a straightforward method to clean your cast iron skillet:
- Rinse and Scrub: Immediately after cooking, rinse your skillet under warm to hot water to remove loose food particles. Use a scrub brush specifically designed for cast iron or a scouring pad to gently scrub away any stuck-on food. It’s perfectly fine to use a small amount of mild dish soap if needed, especially for greasy residue. Contrary to popular belief, a little soap won’t harm your seasoning.
- Rinse Again: Thoroughly rinse the skillet with hot water to remove any soap and food debris.
- Dry Completely: Drying your cast iron skillet immediately is crucial to prevent rust. Wipe the skillet thoroughly with a clean towel. For extra insurance against rust, you can place the skillet on a stovetop burner over medium-high heat until all water evaporates.
- Season Lightly: Once the skillet is completely dry and still slightly warm, add a teaspoon of cooking oil (like canola oil or flaxseed oil) to the pan. Use a paper towel to rub the oil all over the inside and outside surfaces of the skillet, including the bottom. Then, use a fresh part of the paper towel to wipe away any excess oil. You want a very thin layer – the pan should not feel greasy.
- Storage: Store your cast iron skillet in a dry place. You can place a paper towel inside the skillet to absorb any moisture and protect the seasoned surface.
Tackling Stubborn, Stuck-On Food
Sometimes, you might encounter food that’s really stuck to your cast iron skillet. Don’t worry, here’s how to handle it:
- Hot Water and Spatula: For tougher food residue, try using very hot water and a metal spatula. Pour hot water into the skillet and bring it to a simmer on the stovetop. Use the spatula to scrape away the burnt-on food. The hot water helps to loosen the debris, making it easier to remove.

- Salt Scrub: For particularly stubborn bits, create a paste of coarse salt and a little cooking oil. Use a sponge or cloth to scrub the paste in a circular motion over the affected areas. The abrasive salt helps to dislodge the food particles without damaging the seasoning. Rinse thoroughly and proceed with drying and seasoning as usual.
The Importance of Drying Your Cast Iron Thoroughly
Preventing rust is key to cast iron skillet care, and proper drying is the most important step. Moisture is cast iron’s enemy, leading to rust formation.
- Stovetop Drying: After washing and towel-drying, place your skillet on a burner over medium-high heat. This ensures complete evaporation of any remaining water in the pores of the cast iron. You’ll know it’s dry when all visible moisture is gone and the pan is hot to the touch.

Seasoning: Maintaining the Non-Stick Surface
Seasoning is the process of baking oil into the cast iron, creating a slick, non-stick surface and protecting it from rust. Regular seasoning after cleaning is essential for maintaining your skillet’s performance.
- Heat the Skillet: Place your clean, dry cast iron skillet on the stovetop over medium heat and let it get warm.
- Apply Oil: Pour a small amount of oil (canola, flaxseed, or vegetable oil work well) into the warm skillet.
- Rub and Wipe: Use a paper towel to thoroughly rub the oil all over the inside and outside of the skillet, ensuring every surface is lightly coated. Then, use a clean paper towel to wipe away as much oil as possible. The goal is a very thin, almost imperceptible layer of oil.

- Cool Down: Let the skillet cool down completely. For routine maintenance, this single seasoning step after each cleaning is usually sufficient. If you are starting with a newly stripped or rusty skillet, you may need to repeat the seasoning process multiple times to build up a good base.
Common Cast Iron Cleaning Questions
Why is my cast iron skillet sticky?
A sticky cast iron skillet usually indicates too much oil was used during seasoning. The excess oil hasn’t properly polymerized, leading to a gummy residue. To fix this, wash the skillet with hot, soapy water, scrub thoroughly, and then re-season with a very thin layer of oil.
What’s the best oil for seasoning cast iron?
While flaxseed oil is often touted for creating a hard seasoning, it can be expensive and prone to flaking. Canola oil, vegetable oil, and grapeseed oil are excellent, readily available, and affordable alternatives that work very well for cast iron seasoning.
Do I need to season a pre-seasoned cast iron skillet?
Yes, even if your skillet is labeled “pre-seasoned,” it’s beneficial to add another layer of seasoning before first use and after each cleaning. This enhances the factory seasoning and ensures long-term non-stick performance.
Can I season cast iron in the oven?
Absolutely! Oven seasoning is a great method, especially for new or stripped skillets. Preheat your oven to 350°F (175°C). Lightly oil your clean, dry skillet, wipe off excess oil, and place it upside down in the oven for an hour. Place aluminum foil on the bottom rack to catch drips. Let it cool completely in the oven. This is also a method for curing a new cast iron pan.
Is it okay to soak a cast iron skillet?
Never soak your cast iron skillet! Soaking promotes rust. If you need to loosen stuck food, boil water in the skillet on the stovetop and scrape with a spatula instead.
