For the easiest cleaning, rinse with hot water immediately after cooking
Scrub with dish soap and water and a stiff nylon brush or a green scrubbing pad
Some people say to use salt as an abrasive and never use soap, but in my experience, soap works perfectly. They’re worried about the soap washing the seasoning off, but if the seasoning is properly polymerized, this is not an issue.
Dry thoroughly with a towel
Seasoning
I use canola oil because it’s what I have, but flax seed oil is considered the best
Rub oil all over the pan using a paper towel
With a fresh paper towel, try to wipe off all the oil you just put on
Place the pan upside down onto a rack in the middle of your cold oven
Bake at 500°F for 1 hour (start timing when the oven comes to temperature)
Leave the pan in the oven while cooling until room temperature
Repeat 1–4 times for the best seasoning
Derusting & Deep Cleaning
Soak in a 50–50 mix of 5% distilled vinegar and water for 1 hour
Remove the pan from the liquid and sprinkle with baking soda to neutralize the acid
Aggressively scrub with a metal scouring pad
Finish scrubbing with steel wool, rinsing as you go
Once clean, dry thoroughly with a kitchen towel
Heat for a minute or so to ensure complete dryness
