Best way to clean this?

[Tjevxksm]

It's a pretty new oven (tray at the bottom that catches the drips) so I'm gutted I've let it get like this already. I've tried a few different things and it is looking better- but is there any way I can make it look like new again without scratching it?

Will it fit in the dishwasher, if you have one? I'd put it through a cycle, that would soften it. Then I'd work at it with magic sponge.

I'd spray some oven cleaner on it and leaves it for a while. It should then wipe off very easily.

Soak overnight with a dishwasher tablet

Thank you! I started with the laziest option of chucking it into he dishwasher and unfortunately it has made no difference. Looks like it may have to be an oven cleaner job which I was hoping to avoid!

Sprinkle soda crystals on stain. Fill tray with boiling water. Leave to soak. Should lift off quite easily .

That will come off easily with damp wire wool and Pink paste or damp wire wool and Barkeepers friend.
Wear rubber gloves, rub, rinse, then do it again in a year's time. With your best intentions, it will happen again!

The metal scourers will get that off. I also use them for stubborn marks on taps and the tarnish on the top of the toaster

I'd put a scoop of biological wash powder and boiling water and leave to soak.
