Melted plastic wrap in oven at high temp Tonight I preheated my oven, forgetting that I had some dough proofing inside. The dough was sitting in a glassware bowl covered with glad cling wrap and the oven reached about 350F before I realized and took it out. The stretched wrap had a weird hole in the center almost like the plastic had vaporized. Around the sides of the bowl the plastic kind of baked on and got crusty.

Nothing seems to have dripped onto the rack or the inside of the oven and everything came off of the bowl after I washed it with cold water. The dough went in the trash, but is there anything I should do to the oven to make it safe to keep using? I’m worried about plastic particles stuck to the walls of my oven or something. Is the bowl safe to keep using?
It's doubtful the plastic vaporized. It probably just made a hole because it melted and stretched. I'm sure your oven is safe. Any tiny amount of plastic that might have melted and landed on a surface (which is doubtful) would burn and you will smell the burnt plastic. Next time you use your oven just preheat it to 500 for 30 minutes and if there is no smell you're good to go. If you're really worried about it then turn on the self-clean. I would clean the melted plastic off the bowl with a brillo pad.
