What is Seasoning a Pan?
Seasoning a pan is baking oil onto a cast iron skillet through a process called polymerization. This will protect your pan from rust and also make it naturally non-stick without the toxins.
Can You Use Soap on Cast Iron?
The short answer is, yes.
Cast iron pans will not be ruined if you use dish soap, such as dawn, on your cast iron pans. Originally soap was made with lye, and lye is was ruins cast iron pans. Dish soap will remove some of the seasoning on your pan, so you will have to re-season your pans whenever you use dish soap.
If your cast iron pan is already properly seasoned, you just have to be sure to care for it after every use to maintain that wonderful non-stick finish.

Seasoning Your Cast Iron Pan
How do you know if your pan needs to be re-seasoned? It may not have an even, shiny black coat on it, or, you’ll see some discoloration or grey areas.
This happens if you cook something acidic that will eat off the oil, or leave food in your pan overnight and the food eats away at the oil. This can also happen if you use soap on your pan.
Preheat your oven to 450 degrees Fahrenheit.
Oil your cleaned cast iron pan with a small amount of oil (2 teaspoons to about 1 tablespoon). The amount will depend on the size of the pan.
Place your oiled cast iron pan into the oven and bake for 30-60 minutes. Once the pan has been baked, turn off the oven and open the door slightly. Allow the pan to cool in the oven.
Once the cast iron pan has cooled, it should have a nice sheen to it. This is the polymerized layer of oil that will create a non-stick finish to your pan. Store away from moisture of any kind.
