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. A true disservice.
Seasoning is just oil baked onto cast iron through a process called polymerization. It gives your cookware that classic black patina. Seasoning forms a natural, easy-release cooking surface and helps prevent your pan from rusting.

In the case of non-stick stuff, it’s less that they’re seasoned with PFAS and more that they don’t need seasoning because they have PFAS (at least in theory).

Isn’t the “seasoning” PFAS?
Edit: I admit, I was wrong.
