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?

No, that’s the opposite

You can season nearly anything with oil. Except aluminum, which needs a Teflon coating or it gets nasty very fast. Except Teflon is non reactive to nearly everything

Except pfas. You can dissolve Teflon in pfas and spray it onto aluminum

? Teflon is a PFAS
PFAS vs PFOS

Yes, but not spiritually

Teflon doesn’t react with basically anything. It won’t stick to anything but itself, which makes manufacturing difficult, initially we could only make pure Teflon pieces

Every other kind of PFAS is super toxic. Some part of the molecule is reactive, usually very reactive so it sticks to things, and the rest won’t react to anything. That causes nasty problems in biology

Teflon itself isn’t that much of a problem because even if it’s around forever, it doesn’t react with anything… The byproducts of working with it are what are poisoning people and causing all the problems

Anything coated in Teflon are going to have the nasty shit under the Teflon so I’d generally avoid it, but the real take away is that chemical companies are just dumping this shit into water sources knowing it causes super cancer
