Iron cast skillets and other cooking ware can accumulate oils and food residue on the surface with increased usage. And when you frequently use it without cleaning all this leftover residue can quickly turn into grime that gives off a bad odor and makes even cooking difficult. But you can get rid of all this grime using an ingredient that is commonly available in every household. And that is salt! Using a sponge, rub your cast iron skillet with a good amount of salt. It will absorb any residue oils and will not damage the coating. Since salt is available anywhere and everywhere these days, now you have no excuse for those dirty skillets.
