Hello all, first time poster.. I recently cooked with my cast iron skillet on an electric stove, and I noticed there was a large white spot towards the middle of the pan. I thought it might have been a reaction due to the heat I was using, but since the day I've used it (3 days) the spot is still there. Can anyone help me out here, whether it be getting a new skillet, a different way of cleaning it, or if its just fine the way it is.
Thanks a lot!
