Baked-on grease is a common challenge when cooking on baking sheets or griddles. Once it hardens, it can be tough to remove—especially if it's old and encrusted.
Luckily, as a home cleaning expert with years of testing natural solutions, I've found a simple, effective trick using everyday baking soda. No harsh chemicals or pricey cleaners needed!
Apply a baking soda paste to the stain and let it work its magic. Here's how:

1. In a bowl, mix baking soda with water to form a thick paste.
2. Spread the paste generously over the baked-on grease residue.
3. Let it sit for several hours or overnight for best results.
4. Wipe away the paste and loosened grease with a lukewarm sponge or paper towel.

And just like that, the baking soda has lifted the baked-on grease from your baking sheets!
Your kitchen surfaces are now spotless and gleaming. This method is gentle yet powerful, preserving the finish without scratching.
If any residue lingers, simply repeat the process—no scrubbing required.
It works equally well on fresh grease (just sprinkle baking soda on a damp cloth and wipe) or stubborn, old stains. Versatile for stovetops, electric hotplates, drip pans, waffle irons, deep fryers, and oven trays too.
