If your cast iron pan is sticky, you will need to place the pan on top of the stove. Turn the heat on high for 30 seconds to less than one minute. Then, turn it down to medium heat. This will loosen up the oil. Then, you'll need to buff out the creases and the spots. Place a little oil in the pan, approximately 1 tablespoon. Spread the oil around with a paper towel. Continue smoothing the pan. You may need to get a new paper towel, if it gets to hot. This often happens, when too much oil is applied to a pan, when you are seasoning it. When that oil heats and dries, it distorts the pan.
