After this I dry with a paper towel, pour (or spray) a little oil in the skillet and wipe around with the same paper towel. Last, I heat on the stove (med high heat) until it smokes and then remove from heat. This seasons and dries the skillet at the same time. Seasoning makes the skillet stick-free and prevents it from rusting. That is it!
