Keeping your baking sheet clean isn't just about appearance -- it's about hygiene and performance. Here's how to do it right, with the supplies you probably already have at home.
Cover the entire baking sheet with a generous layer of baking soda.
Pour hydrogen peroxide over the baking soda. The two react to break down baked-on grease.
Add another light layer of baking soda over the wet mixture. Let it sit for 2 hours.
Scrub with a sponge or plastic scraper. The brown burnt-on residue lifts off without aggressive scrubbing.
Wash with dish soap and warm water to remove any residue. Dry thoroughly.
