I have a teflon pan that was left on the stove with water in it, set

Anything that can be done with it or is it trashed?

Wash it out and continue to use it if you want. Finish may not work as
well but there is no health hazard. You cannot restore the finish.
Hazard of overheating teflon will cause flu like symptoms to you but
maybe kill your canaries, whatever, as birds have higher respiratory
requirements. Same thing could happen to birds in all metal pan burning
food.


Well, if you generate enough smoke, I guess it's true that food
burning in any metal pan could kill birds at some point. But teflon
heated to high temp generates a specific chemical that is highly toxic
and will kill biirds. A stainless, cast iron, etc will not do that,
so its not all the same.

As for the question, if the pan was overheated on for a considerable
time and won't clean up, then it should be thrown out.





Don't worry teflon is now under suspicion in certain countries as a
possible cancer causative.
So no matter what the colour it's probably done it's deadly work
anyway.
If you DO have any doubts however; throw it away!
Yes; during the last 50 years we have had teflon coated cooking pans/
utensils.
One of us has died, probably unconnected to use of teflon? I'm still
here.
