Cast iron woks are one of the most rewarding tools in any kitchen — they hold heat beautifully, develop a natural non-stick seasoning over time, and only get better with use. But they do need a little love. Here's how to keep yours in perfect shape for years to come.
Season It Before First Use
Before cooking anything, rinse your wok with warm water, dry it completely, then rub a thin layer of high-smoke-point oil (like flaxseed, vegetable, or canola) all over the surface — inside and out. Place it upside down in a 450°F oven for an hour, then let it cool inside the oven. This builds the foundation of your seasoning.
Clean It the Right Way
Skip the dish soap and never soak it. After cooking, while the wok is still warm, use a stiff brush or chainmail scrubber with hot water to remove food residue. For stubborn bits, add a little coarse salt and scrub gently. Rinse and dry immediately — cast iron and moisture are not friends.
Dry It Thoroughly Every Time
After rinsing, place your wok on the stovetop over low heat for a minute or two to evaporate any remaining moisture. Then rub a very thin layer of oil over the surface with a paper towel before storing. This keeps rust at bay and builds up your seasoning with every use.
Re-Season When Needed
If your wok starts to look dull, develops rust spots, or food begins sticking, it's time to re-season. Scrub off any rust with steel wool, wash, dry completely, and repeat the oven seasoning process. It'll be good as new.
What to Avoid
- Acidic foods (like tomatoes or citrus) for long cook times — they can strip seasoning
- Dishwashers — always hand wash
- Leaving it wet or storing with a lid on tight (traps moisture)
Cook With It Often
The best thing you can do for a cast iron wok is use it regularly. Every stir-fry, sear, and sauté adds to its seasoning and makes it more non-stick over time.
