Another cast iron pan question

I have reclaimed several awesome cast iron pans over the years, the worst one I found in an old abandoned barn. It had a hundred years of rust and everybody said it would be impossible to ever get it clean and useable again. I clean them the way granddaddy taught me, build a big fire and set the pan in the coals. Cover it with coals and get it red hot. After the fire is out and the pan is completely cool you can wash it and it will be brand spanking new again.
Never wet a hot pan with cold water, it will crack and become an anchor. Season with grease and wipe clean after use. It will last forever.
