The industry life expectation for Teflon and related non-stick cooking surfaces is around five years. I've had it last a lot longer, but only because I take very good care of my pans. Overheating Teflon will kill it, and transform it into a substance that you don't want to eat. Teflon is good for some types of cooking, and not appropriate for many others. Tom
We replace our "non-stick" skillets yearly, just because of teflon concerns. For most cooking, I prefer the big, heavy cast iron skillet that lives on our stovetop! The waffle iron we have is cast iron. I use coconut oil, applied with a natural bristle paint brush, to oil it up. I haven't used "spray oil" in many, many years, after I discovered that it left a shelac-type residue on my baking pans. Wow, that was probably in the late '80s, early '90s.
We don't have teflon pans... there are too many birds that are brought over to our home... I don't want to poison them.
That happened to my DH and his first spouse. They raised budgies, and one day she left a pan on the stove... the fumes killed nearly all their birds. It's really important, when using non-stick pans, to use lower heat. NEVER use high heat with them. Better to not use them at all! Personally, I would not own a non-stick pan if it were me - however, DH (who does a lot of the cooking) prefers a non-stick for some of his cooking. He will use the cast iron skillet more often, though.
They only deliver to people with money.. I'm broke right now. Atleast I make my car payment monthly. haha
