My mother recently gave me a 9" Le Creuset cast iron skillet as a wedding gift. I've only used it twice, and there seems to be an orange/brown stain on it that won't come up. Is it rust?? Also half the pan looks brand new and smooth and the other half has this sort of texture to it. Please help me! I'm not sure what to do! :'(
I've attached photos. The first one shows the orange stain at the top center, the second shows the textured pan. Any advice would be greatly appreciated!
