However, it does requires a little extra care, which can feel intimidating if you're used to stainless steel or ceramic. But don’t stress! After reading this guide, you should feel more comfortable with using and maintaining cast iron so you can enjoy all it's benefits.
Why Cast Iron Is Worth the Effort

How to Prevent and Remove Rust
The biggest enemy to cast iron is moisture. It will rust very quickly if it is not dried thoroughly and seasoned before storing. If you notice a small patch of rust, it is best to use a cloth with some salt to scrub it until the rust is gone.For heavier rust, a vinegar soak can help. Mix equal parts white vinegar and water, then submerge the pan, check it every 15 minutes. As soon as the rust starts flaking off, remove the pan and wash. If you leave it in the vinegar too long, it can damage the metal. If your pan is heavily rusted, especially those second hand pieces of old cast iron, you may need to sandblast it to loosen all the rust.Seasoning Your Cast Iron Pan
Seasoning might sound complicated, but it’s actually simple. All you’re doing is coating the pan with oil and heating it until the oil forms a protective, non-stick layer. Here’s how:- Preheat your oven to 500°F
- Coat your pan lightly with oil—just enough for a thin, even layer. You do not want a lot of oil because the heat of the oven could cause a grease fire. Also, a cheap vegetable oil works best for this due to its high smoke point.
- Bake for an hour. Place the pan in the oven and let the oil do its thing. Make sure you turn on the range hood fan or open a window, because the oil will smoke slightly.
- Repeat if needed. You an repeat this 2-3 times, just cool the pan and start the process over.
Cleaning and Maintenance
The key to cleaning cast iron is protecting the seasoning. Keep these two rules in mind:- Skip the soap—this is a controversial topic amongst cast iron users but in my experience it can strip away the seasoning.
- Avoid harsh scrubbing tools like steel wool.
