To maintain the longevity and quality of a cast iron skillet, there are certain things you should never do:
Never use soap: Avoid using soap when cleaning your cast iron skillet. Soap can strip away the seasoning, which is the natural, non-stick coating that develops over time. Instead, use hot water and a stiff brush or a non-metal scrubber to clean it after each use.
Avoid metal utensils: Refrain from using metal utensils, such as metal spatulas or forks, when cooking in a cast iron skillet. These can scratch and damage the seasoning. Opt for wooden, silicone, or nylon utensils instead.
Don't soak it in water: Extended soaking can cause rust to develop on the cast iron surface. After cleaning, always make sure to dry the skillet thoroughly.
Avoid cooking highly acidic foods: Avoid cooking highly acidic foods for prolonged periods, as the acid can react with the iron and compromise the seasoning. It's fine to cook acidic foods occasionally, but try not to leave them in the skillet for too long.
Don't put it in the dishwasher: Never put your cast iron skillet in the dishwasher. The high heat, powerful detergents, and prolonged exposure to water can damage the skillet and remove the seasoning.
Avoid extreme temperature changes: Avoid subjecting your cast iron skillet to extreme temperature changes, such as transferring it from a hot stovetop directly to a cold surface or submerging it in cold water when it's still hot. This can cause the skillet to warp or crack.
Don't store food in it: Avoid leaving food in the cast iron skillet after cooking, especially if it's acidic or salty. The food can interact with the iron and affect the seasoning.
Never use it on glass-top stoves: Cast iron skillets can be heavy and may scratch or damage glass-top stoves. It's best to use them on gas or electric coil stoves instead.
Remember that the seasoning on a cast iron skillet is its natural non-stick coating, and taking care of it will make your skillet last for generations. With proper care and maintenance, a cast iron skillet can become an excellent cooking tool that improves with age.
