Quick answerMix baking soda with water into a spreadable paste, coat the inside of a cool oven, and leave it overnight. Wipe everything out the next day, then spray white vinegar on the remaining film and wipe clean. It handles months of baked-on grease with zero fumes.
What you'll need
- 1/2 cup baking soda (grab more for a very dirty oven)
- Water
- White vinegar in a spray bottle
- Dish soap
- Rubber gloves
- A plastic spatula or old credit card
- Non-scratch scouring pad
- Microfiber cloths or old towels
- Small bowl
Step-by-step
- Empty the oven and pull the racks. Take everything out — racks, thermometer, pizza stone, all of it. Put the racks in the sink or bathtub to deal with separately. Make sure the oven is completely cool before you start.
- Mix the paste. About half a cup of baking soda with a few tablespoons of water. You're aiming for cake-frosting consistency — spreadable, not runny. Add the water slowly; you can always add more, but you can't take it out.
- Coat the inside. Gloves on, spread the paste over every interior surface: walls, floor, door glass. Go thick on the greasy spots. Keep it off the heating elements (and the gas inlet on a gas oven) — paste baked onto elements smokes when you next cook.
- Wait overnight. Twelve hours minimum. The baking soda slowly loosens carbonized grease while you sleep. This is the entire trick, and there's no shortcut that works as well. Close the door and walk away.
- Wipe it all out. Damp cloth, working in sections, rinsing the cloth often. A plastic spatula helps lift the stubborn patches. It'll come away brown and gross — that's the grease leaving, which is exactly what you want.
- Hit the residue with vinegar. Spray white vinegar over the thin white film left behind. It'll fizz a little. Wipe clean with a damp cloth, and repeat on any hazy patches until the glass is clear.
- Do the racks. Soak them in hot water with a good squirt of dish soap — the bathtub is easiest for full-size racks. Scrub with the scouring pad, rinse, dry, and slide them back in. Run the oven empty at 200°F (95°C) for 15 minutes to dry everything out fully.
<div class="safety"> <strong>🛑 Stop and call a pro if:</strong> <ul> <li>You smell gas at any point — turn everything off, leave the kitchen, and call your gas company. Never troubleshoot a gas smell yourself.</li> <li>The oven won't heat after cleaning — you may have damaged a heating element or sensor. Don't poke at wiring; call an appliance tech.</li> <li>Your oven has a self-cleaning cycle — run self-clean OR do this method, not both back to back. Check the manual first.</li> </ul> </div>

Frequently asked questions
Will this work on really baked-on, blackened grease?
Yes — that's exactly what it's for. For the worst spots, apply a second round of paste and give it another few hours. What it won't fix is grease sitting on damaged enamel. If the coating is chipped underneath, no cleaner will make it look new.
Can I just use the self-cleaning cycle instead?
You can, but self-clean runs the oven extremely hot for hours. It can trip breakers, fill the kitchen with smoke, and in rare cases damage the control panel. The baking soda method is slower but much gentler. Pick one method — don't do both on the same day.
Is baking soda safe for self-cleaning ovens?
The paste itself is fine on the enamel. Just keep it off the door gasket and away from the convection fan area if your manual says to keep that clear. When in doubt, check the manual for your model.
How often should I do this?
A lighter version every 2–3 months stops heavy buildup from forming. If you roast meat weekly, do the full overnight treatment twice a year and you'll never face a crisis clean again.
