Open your oven right now. Go ahead. That crusty, burnt-on mess on the bottom has probably been there so long you've stopped even seeing it — until you're hosting people and suddenly it's the only thing you can see.

Most people's solution is either an expensive oven-cleaning spray that smells like a chemistry lab, or the self-clean cycle that turns your kitchen into a sauna and sets off every smoke alarm in the house. There's a better way, and it's sitting in your pantry right now: baking soda, water, and time.

1. Mix a Thick Baking Soda Paste

Combine and stir: Mix about half a cup of baking soda with a few tablespoons of water until it forms a spreadable paste, roughly the texture of frosting. Don't add too much water or it'll just run right off the surfaces.

2. Spread It Generously Inside the Oven

Coat the grimy spots: Remove the racks, then spread the paste all over the interior, focusing heavily on the bottom and any visibly burnt or stained areas. Avoid the heating elements — just the walls, floor, and glass door.

3. Let It Sit Overnight (Seriously, Just Walk Away)

Do nothing for 8+ hours: Close the oven door and leave it alone overnight, or at least 6-8 hours. This is the part that feels almost too easy, but the paste needs time to break down all that baked-on grease and carbon.

4. Wipe It Out With a Vinegar Spray

Spritz and scrape: In the morning, spray the dried paste with white vinegar in a spray bottle — it'll fizz slightly. Wipe everything out with a damp cloth; the grime should come away in sheets instead of requiring any real scrubbing.

5. Soak the Racks Separately While You Wait

Double up on the time: While the oven interior sits overnight, soak the racks in a bathtub or large tub with hot water, dish soap, and a splash of vinegar. By morning they wipe clean in seconds too.

The Real Win Here

Total hands-on time: about 10 minutes to spread the paste, and 5 minutes to wipe it out the next day. No fumes, no scrubbing until your arm gives out, no hundred-dollar oven-cleaning service. Just two cheap ingredients and letting time do the actual work while you sleep.
