Cast iron pots and pans need to be seasoned. To season cast iron cookware, heat your oven to 300 degrees F, lightly rub the entire cooking surface with canola oil, shortening or lard, and place it in the oven for one hour. Remove the cookware from the oven and let it cool.
Cast iron cookware should be washed with hot water and a mild liquid dishwashing soap. Rinse well and dry thoroughly. Place paper towels inside the pot to absorb any moisture. The excess moisture can cause rust.
To clean tough, burned-on food stains, pour vegetable oil in the bottom of the pan and sprinkle with sand. Scour with a steel wool pad. After you have cleaned cast iron like this, it will need to be seasoned again.
To clean rust from cast iron pots and pans, make a paste of ascorbic acid and water and scrub the rusted area. If the cookware has a lot of rust or stubborn rust, leave the paste on overnight and then scrub. After you have cleaned the rust, the pan will need to be seasoned again.
