potoooooooo ✅️She's out of town and I'm cleaning her entire collection as a surprise
brokenwingPlease 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.
daggermoonIsn’t the “seasoning” PFAS?
That’s the stuff on standard non-stick pans (teflon). You don’t make PFAS by burning in some oil at home.
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).
theneverfoxNo, 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
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
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
CatoblepasPlastics made from petroleum aren’t the same thing as heated up vegetable oil.
No, and nor is the teflon in the pans you’re thinking if. PFAS is a chemical used in the manufacture of Teflon (or was, I thought they’d stopped now) not teflon itself.
The problem with PFAS is accidental release and dumping.

TonavaPFAS is a chemical
PFAS is the term for the whole group of the stuffs called “forever chemicals” (for a reason). There’s not just a single one, but multiple, and as the specific ones and groups get banned, the industries move to use different ones, basically. It’s important to buy “PFAS free” stuff, any other labels like “PFOA free” can still mean there’s PFASs there, there’s just not ones from the specific variation
Damn, you’re right, I was thinking of PFOA not PFAS.
However, I think blanket avoiding an entire class of chemicals without evidence is an overreaction.
LeonI think in the case of PFAS it’s very reasonable. There’s no real harm done in avoiding them except possibly making less money and having to figure out other ways to do certain things - which cannot even be compared to the the potential danger they pose to the whole ecosphere
Well if we have evidence of that sure, but in the case of PTFE for example (which is a PFAS) we don’t have that, so banning it seems just as nonsensical. Yos be banning it because it might be harmful.
But the thing is, if it turns out to be harmful, it’s too late if we have used it - we can’t get it out of nature anymore. Which is a fucking big risk to take considering the effects research has already proven with the other PFAS. That’s kinda the whole problem with persistent organic pollutants
How is it an overreaction if it can be done without losing anything in life? I retired all my pans with non-stick coating years ago and haven’t missed them a single time and appreciate that it makes it easier to minimize the number of plastic cooking utensils my kitchen has, too.
Yeah but if I use stainless steel pans, I can use stainless steel wool to clean them, so the sticking doesn’t really matter aa much when it does happen, plus cooking techniques can reduce or eliminate sticking even on stainless steel. So I’ll adjust to say I’m not losing anything I value.
And I don’t have a huge issue with it being used on things that doesn’t touch our skin or food/water often. And my goal is to minimize exposure in this plastic world. I understand that at least some restaurants (if not most that use pans) probably use nonstick pans and that I’m getting exposed to BPA every time I touch a receipt. So I don’t use those pans at home and don’t let receipts linger in my hands and use gloves when going through a bunch of them.
Cool, I’m not gonna tell you you must use teflon pans, but I think we were talking about bans…
Looking back at the thread, bans were mentioned, but the context that I was following looked like it was about wanting to go beyond what’s banned because the industry just rotates in variations of the chemicals whenever specific ones are banned.
