This!!!
But wear one of your covid masks, C.I. has a way of getting deep into your sinuses and lungs, then you will taste that crap for the whole day. I have worn out many thousands of grinding wheels working with C.I. pipe and fittings for waste and drain lines, that C.I taste is brutal, and it can't be good for you.
Lodge C.I. are rough because of the casting sand that they use, not because of the spray on seasoning.
There is no way you are going to get them smooth by scraping them, if you want a smooth C.I. pan either use it as often as you can or hit it with a sanding wheel, then reseason with soybean oil.
This is a pretty cool vid.
