Spray it with oven cleaner let it set then wash it off.

There is also a product called Bar Keepers Friend. It is a powder like Comet but works much better. It takes off a lot of things really good. I would not be without it.

Good luck

Let it soak over night with hot water bleach and a small squirt
of dish washing liquid.(Dawn)The next day you may wash it out with a plastic scouring pad and soap of your choice.////An alternative is water and fire from top of your stove.-You may also put water in your dish in the oven and bake it lose.{WARNING}DO NOT TRY THIS AT HOME AROUND CHILDREN.

I use glass baking dishes for all my cooking, baking etc.
I use the dishwasher to wash all my glass ware.
It is tremendous, I have been doing this for about 12 to 15 years and my glass baking dishes look like new.
Especially when you have baked chips in them, just one wash in the dishwasher and they are sparkly.
I have dishes that are over 20 years old and not a mark on them.

Soak it in hot soap water then take a Brillo pad to it. That’s how I do mine and it gets them clean every time…
