A damaged cooking surface is another.
Keep Your Baking Sheets Cleaner for Longer
Once you’ve restored a pan, a little maintenance can prevent future buildup.
Try to clean baking sheets soon after use instead of allowing grease to sit on them for days.
Don’t allow food residue to repeatedly bake onto the surface.
And when appropriate, use parchment paper or a suitable baking liner to reduce direct contact between food and the pan.
The Bottom Line
A stained baking sheet doesn’t necessarily belong in the trash.
With warm water, dish soap, baking soda, patience, and the right technique, many stubborn stains and layers of residue can be reduced considerably.
But remember that the safest cleaning method depends on the material and coating of your pan.
