Non-stick cookware, commonly coated with PTFE (Teflon), poses significant health and environmental risks due to the release of PFAS ("forever chemicals") when overheated above 500°F (260°C) or scratched

If scratched the cost of a replacement is not bank breaking.
On the cleaning.
Last year we cooked a chicken in the Ninja Speedi and removed the chicken and went away for 1 week.
On return we noticed the smell first and then when opening the Speedi lid, realised we had left and forgot to clean it.
The surfaces were totally scratch free and the surface was non stick.
Tried the dishwasher tab idea, then bleach, then napalm, but no matter what, the odour of off meat would never leave the bowl, so out it went and a not overly expensive original replacement was ordered.
That was a genuine mistake, as we always clean and wash after every use, but shows that that non stick coating is not 100% bullet proof.
