Oh fuckkk. 
I’m such an idiot!!!
Put some stuff in a baking tray to cook in the oven earlier.
I hadn’t realised, but it seems like there was a plastic/rubber heatproof mat attached to the bottom of the baking tray!!
Can’t believe I didn’t notice. I kept on hearing weird popping sounds from the oven while the stuff in the baking tray was cooking. Fuck.
Anyway, the plastic or rubber heatproof mat thing (or whatever it was that was attached to the bottom of the baking tray) has melted after being in the oven!! And it’s covering the bottom part of the oven! It looks weird and clingfilm-y.
Any ideas about how I can get it off please?
I’ve turned the oven off, and am waiting for it all to cool completely.
Fuck, I’m such an idiot!!!
