She's out of town and I'm cleaning her entire collection as a surprise

Please someone explain!
Cast iron is “seasoned” to make it nonstick. That means many layers of oil build up as a sort of polymer. The point is to keep it “dirty” in this way. Cleaning it down to bare metal means she’d be forced to re-season it, which can take considerable time/effort depending on frequency of use.
Isn’t the “seasoning” PFAS?
The seasoning is plastic. That’s what polymerized means. The F in PFAS stands for flourine which I don’t think you’ll have in your seasoning
Plastics made from petroleum aren’t the same thing as heated up vegetable oil.
Did they sayil it was?
