Holiday baking shifts our cookie sheets into overdrive. Over the past few months, these trusted kitchen tools have seen it all—from spicy-sweet gingersnaps to Santa-shaped sugar cookies. Amidst the frenzy of the season, giving our hardworking kitchen tools some much-needed TLC falls to the wayside. Now that the holiday hustle is over and the New Year has begun, make a resolution to wipe down your whole kitchen, including its trusted tools and appliances (like the oven and stand mixer).

After months and years of use, cookie sheets can build up some seriously baked-on grime. When dish soap just won’t do the trick for eradicating gunk, it’s time for a stronger solution. The best part? It’s incredibly easy—and the ingredients are probably already in your pantry. All you need is baking soda and hydrogen peroxide; the two combine to create a grime-fighting formula that will leave your cookie sheet looking brand-new.

Start by sprinkling a generous amount of baking soda over the cookie sheet. Next, cover it in hydrogen peroxide. Then sprinkle another layer of baking soda on top. Let it sit for up to two hours (the longer the cookie sheet soaks, the more baked-on residue that will come off). Wipe it off with a sponge to reveal a clean pan that looks as good as new—no heavy scrubbing required. If some stains are remaining, repeat the cleaning process again. With a stain-free cookie sheet, you’ll be ready to tackle the next big season of baking.
