Fresh cookies out of the oven, but dreading the baked-on mess on your baking sheet? As a seasoned home cook and cleaning enthusiast, I've tested countless methods, and this simple trick delivers sparkling results without any scrubbing.
All you need: baking soda and hydrogen peroxide (also known as hydrogen peroxide solution).
Proof in pictures:

And here's how it works in action (video demo):
1. Sprinkle a generous layer of baking soda over the baking sheet.
2. Pour 10% hydrogen peroxide just enough to moisten the baking soda layer.
3. Add a second layer of baking soda on top.
4. Let it sit for 2 hours, then rinse off the mixture with water. For tougher spots, repeat the process.
This method lifts grease, burnt residue, and stuck-on food effortlessly—no scrubbing required!
Your baking sheet will look brand new. For faster results, mix baking soda and hydrogen peroxide into a paste and gently rub it on. It works wonders on other kitchen utensils too.
