Maintaining Carbon Steel Cookware
Carbon steel is maintained by building and protecting a polymerized layer of oil, known as seasoning. After every use, wash with warm water and a brush, dry it thoroughly over low heat, and apply a drop of oil to prevent rust before storing in a dry place.
Commitment is part of the tool.
Carbon steel acts like cast iron but responds faster to temperature changes. Treat the seasoning as a living surface that improves the more you cook with it.

- Lint-free cotton cloth or paper towels
- High-smoke point oil (grapeseed or canola)
- Stovetop
Thermal Drying
Never leave a carbon steel pan to air dry. The moment it touches water, it wants to rust; set it on a burner over low heat for two minutes until every trace of moisture evaporates.
The method.
Clean immediately
While the pan is still warm, wash under warm water. Use a stiff brush for stuck bits. Avoid soap if possible, but use a small drop if needed to remove grease; never soak the pan.
Dry completely
Wipe the interior and exterior dry with a cloth. Place it on the stovetop over low heat until the metal looks matte and bone-dry.
Oil the surface
Apply a half-teaspoon of oil to the interior. Use a paper towel to buff it across the surface, then switch to a clean side of the towel and buff it again until the pan looks almost dry. Any excess oil left behind will turn sticky.
Final heat
Leave the pan on the heat for another minute until you see the faint shimmer of the oil. Turn off the heat and let it cool completely.
Other turns to take.
The Reset
If the surface becomes uneven or gummy, scrub it down to the raw grey metal using steel wool or a scouring pad, then perform an initial seasoning by heating oil until it smokes.
When it doesn't go to plan.
Acidic ingredients like tomatoes or wine will strip your seasoning; avoid simmering these for long periods until your pan has a heavy, dark patina.
If you see a spot of rust, scrub it away with a scouring pad and re-oil the area immediately.
Store your pan in a low-humidity area, or hang it on a rack rather than stacking it where it might trap moisture.
The ones that keep coming up.
Does it need to be black to be working correctly?
A dark brown or black surface indicates a well-developed patina, which provides the best non-stick properties. It takes time and consistent use to get there; don't worry about the color during the first few weeks.
Can I use metal utensils?
Yes, carbon steel is durable. Metal spatulas are excellent for scraping the bottom of the pan while cooking, which actually helps keep the seasoning layer smooth.
