Pour a quarter-sized amount of vegetable oil in the skillet and wipe it around with a paper towel to coat the skillet and remove excess oil. Preheat the skillet over low heat. Allow cold food to warm up on the counter to avoid damaging the pan by placing cold food in the warm pan.
Wash your Lodge pre-seasoned skillet with warm water and a nylon dish scrubber. Do not use detergent, since it will remove the seasoned coating on the skillet. Scrub the skillet immediately after cooking, while the pan is still warm, for easiest removal of food stains. Treat hard-to-remove stains by filling the skillet with 1 to 2 inches of water and bringing it to a boil. This softens the food so it can be scrubbed out with a nylon scrubber.
Dry your Lodge pre-seasoned skillet immediately after washing. Should the skillet end up accidentally air-drying, resulting in rust, scrub the rust off with a steel wool pad. Wash the skillet out with warm water and the nylon dish scrubber and then dry it thoroughly.
Season your skillet if it begins to look gray or food starts sticking to it while you cook. Clean the skillet with a few drops of dishwashing detergent and warm water. Since the skillet will be seasoned, it's acceptable to wash it with dish detergent before seasoning.
Coat the inside of the skillet with vegetable oil. Place the skillet upside-down on a baking sheet and bake it in an oven preheated to 350 degrees Fahrenheit. Leave the skillet in the oven to bake for one hour. Turn the heat off and allow the skillet to remain in the oven until completely cooled.
Store your Lodge pre-seasoned skillet in a dry location. Keep it in the oven between uses, if possible, but always remember to remove it before turning the oven on.
