I make it a point to discard the pan no matter what brand at the first signs of it's loosing it's non stick performance and when the grime starts to slighty stick despite intensive hand washing.
My girlies all agree, never to wash in diswasher, so I obediently comply.
Tefal brand only ? why not, but at the end they all have limited lifespan,???? no matter how careful you are.
To make it simple, use it normally but avoid using it without oil as some people do, and above all, discard and chage at the first signs of use. Not to say if it's healthy or not, I think all the coca cola mixers I used in my party years in my Jack-Coke will catch up faster, then the pan's teflon coating.
