I have a pan/wok that I use for toasting flatbreads.
Yesterday, I placed it in my cupboard while it was still hot and it accidentally touched a plastic bag full of salt. The plastic immediately melted off and stuck to the pan.
I was able to peel off the plastic after it had solidified, but am worried there may still be some "invisible" remnants left (I have no idea if that's possible). I'm not sure what plastic the bag was made out of or anything: should I discard the pan? Or is it sufficient to wash it well?
