Even though cast iron is durable and can be brought back to life after suffering considerable abuse the best thing you can do for your cast iron cookware is take good care of it.
Seasoned cast iron utensils can be very easily cleaned with nothing more than boiling water and a stiff-bristled brush. DO NOT use soap or detergent. DO NOT use a scouring pad. To do so will break down the seasoned coating. You can also use foil to clean your seasoned pan. The aluminum foil gets rid of any cooked on food and does no damage to the pan’s finish. If you frequently use foil in your culinary endeavors you may appreciate a second use for it before it is discarded.
It’s important to ensure that your cast iron utensils dry completely after use or else they will be subject to oxidization and rust.
A thin coat of oil, wiped on with a paper towel (be very sparing here) will help preserve the metal while being stored. Be sure to store your cookware in a dry area.
Expect your cast iron utensils to darken with use. Cast iron cookware comes to life in a medium gray suit but over time begins to show its true colors. It gets darker and darker until it wears its signature black. This is normal and means that in your capable hands your cast iron cookware has found a place to call home!
