Rust is a common problem for cast iron cookware, but it can be removed with a few simple steps. Rust is a type of corrosion that forms on iron when it is exposed to moisture and oxygen. It can cause the metal to become pitted and weak, and it can also affect the taste of food cooked in the pan.
There are a few different ways to remove rust from cast iron cookware. One method is to use a vinegar and baking soda paste. To make the paste, combine equal parts vinegar and baking soda in a bowl. Apply the paste to the rusty area and let it sit for 30 minutes. After 30 minutes, scrub the area with a sponge or brush to remove the rust.
