Ammonia
Steel Wool
Plastic Garbage Bag
Directions:

Place the stained baking sheets inside a plastic bag and add approximately 1/2 cup of ammonia to the bag.
Seal the bag tightly and let it bask in the sun for an entire day. During this time, the ammonia will work to soften and break down the stubborn oils and grime.
After a day of soaking, open the bag and use steel wool to scrub the baking sheet. The oil and gunk should come off with relative ease.
Thoroughly rinse the sheet to remove any remaining ammonia residue.
A word of caution: When working with ammonia, take safety precautions. Keep it out of reach of children, avoid inhaling its fumes, and wear protective gloves and eyewear.

Before applying any of these methods to your baking sheets, it’s wise to test a small area to ensure they won’t damage the sheet’s surface.
