I melted a nylon spatula inside of my cast iron skillet fry pan ... Do I have to toss it out?
Because it's been subjected to heat? I don't know that that does any harm to the food the spatula may touch in the future. I doubt it, but await until someone more knowledgeable posts.
I melted the handle of a potato peeler in a similar fashion, years ago, have kept it, and thus have a unique potato peeler.
