New Nonstick Cookware Sheds PTFE Particles Before Visible Wear Appears
We Tested Nonstick Cookware: Coatings Don't Need to Look Worn to Shed Particles
We tested new PTFE-coated skillets and air fryer baskets to see if they release particles into food before showing visible damage. Our results show that even brand-new cookware can shed detectable particles, and mechanical wear significantly increases this shedding. Surprisingly, higher-priced models like the All-Clad D3 released more particles than cheaper alternatives, suggesting price is not a reliable indicator of durability.
The common advice to replace nonstick cookware once it becomes visibly damaged is flawed because particle shedding can occur long before obvious scratches or peeling appear.

I’m the founder of RTINGS.com. A few notes about this investigation:
- For each piece of cookware, we purchased and tested three separate units
- Before taking the “new” measurement, each unit was washed three times with dish soap and rinsed with isopropyl alcohol
- Oil blanks and uncoated cookware were included as controls
- We did not chemically identify the particles that were released
- This investigation measured particle release, not toxicity or health risk

I don't have any nonstick. It's not that hard to cook anything or to clean stainless or cast iron. For cast iron/carbon steel 99% of the time I run it under water and rub it with my hand and it comes clean in 30 seconds. Rarely I use some soap.
Stainless comes clean easiest right after you use it. Especially if you pour a little water on it while it's still hot. I do occasionally use an SOS on stainless.
There's nothing I'm unable to cook with my pans. I make french omelettes in stainless steel pans and they come out perfect.

Thank you for these tests!
I've recently tossed all my coated pans (my favourite were the Anolon, but those too shed) and moved to stainless steel, save for a cast iron and carbon steel pan.
In the journey here the best I could find was a Hestan nanobond pan, which unfortunately laminated and has shown some pits after few months of use. They refunded me but titaniums isn't yet where stainless steel is.
Now I'm using a mix of Demeyere, De Buyer, and Made In.
It takes a bit of time to get used cooking in them without a ton of fat.
Look up Leidenfrost effect on youtube and you'll learn pretty quickly how to use stainless steel and do not let anything stick even fish.

My observations from experience:
- Nonstick helps, but don't use it instead of a fat.
- Ceramic works well enough that I'm shocked Teflon nonstick still exists. No reason to risk it.
- Use real food. Real butter, real olive for most things, real peanut oil for high temp.
- If you don't overeat or or eat junk or indulgences too often, you can eat anything you want, just not every day.
- Variety and exploration inherently limits bad habits.
- Nobody has time to scratch cook every meal. Cook batches and freeze them. If you use occasions when you have time to do this, you'll build up a variety in your freezer that you won't hate anything before you run out of it. OTOH 16 chicken burritos is at least five too many. Trust me.
- All of this is much easier if you're cooking for yourself or for like-minded people.

PTFE is not the only way to get "nonstick" cookware.
The amount of stickiness perceived is 99% a skill / procedural issue.
