I’ve been an absolute numpty
I left a Joseph Joseph microwave lid in the combo oven (having used it as a plate to stand the bowl of baked beans on in case they spilt/over flowed)
I’ve now turned the oven on to cook dinner. And on high too.
The stench is hideous
The smoke is hideous
The lid thing is now a splodge of runny melted plastic on the floor of the oven.
The New oven. 
What shall I do?
Wait until it’s conpletely cooled and hope that it peels off?
Wipe off now?
Help please.
