To clean a cast-iron skillet
Wipe the interior surface of a still-warm skillet with paper towels to remove any excess food and oil. Rinse under hot running water, scrubbing with nonmetal brush or nonabrasive scrub pad to remove any traces of food. Dry thoroughly with paper towels and heat on the stove at low heat to get rid of any remaining moisture. Moisturise the surface by wiping on a little cooking oil with a paper towel.
