Baked on pumpkin pie filling

Start with if it's non- stick, sprinkle it with baking soda, and pour a little hot water over it in the sink. Let it sit for about 30 minutes, then scrub with a sponge. If it's not a non-stick sprinkle salt with a little hot water in the sink and let that sit 30 minutes, then scrub with a good paper towel, then, use SOS, and rinse. If you need to, repeat.

When baking anything that may drip, like pies, I line the cookie sheet with parchment paper for easy cleanup. You can also use aluminum foil, just have the dull side facing up.

Try soaking with fabric softener or hair conditionser. You can also try spray on oven cleaner.

Sounds insane, but this works. Put your pizza pan in the sink, line with softener sheets, add enough water to cover. Let sit over night and it should come perfectly clean. I've tried it when I thought I would have to throw the pan away and it worked.

Start with a dry pan. Pour undiluted concentrated Dawn on the burnt part and let it sit for at least 30 minutes before you scrub with a green pad or a metal scouring pad. Depending on the thickness, you may have to repeat this process.
