Commercial oven cleaners work, but the fumes are brutal and the chemical residue lingers for days. Cleaning oven with baking soda achieves the same grease-cutting results using ingredients you already own, with zero toxic off-gassing. This method costs under $2 per cleaning and handles even heavily neglected ovens that have not been scrubbed in months.

What You Need
- Baking soda — 1/2 cup (one standard box keeps you covered for several cleanings)
- White vinegar — in a spray bottle
- Water — about 3 tablespoons to make the paste
- Dish soap — a few drops (optional, boosts grease cutting)
- Rubber gloves
- Non-scratch sponge or nylon scrub pad
- Old towels or paper towels for wiping
- Plastic or silicone spatula for scraping thick buildup
Step 1: Remove Racks and Loose Debris
Pull out all oven racks and set them in the kitchen sink or bathtub. Brush out any large crumbs or charred food bits from the oven floor with a dry cloth. Cleaning oven with baking soda works best when you start with the loose debris cleared out so the paste contacts the actual baked-on residue.
Step 2: Make the Baking Soda Paste
Mix 1/2 cup of baking soda with 3 tablespoons of water in a small bowl. Stir until you get a thick, spreadable paste with the consistency of toothpaste. Add a few drops of dish soap if your oven has heavy grease buildup. For extra-tough jobs, increase to 3/4 cup baking soda.
Step 3: Apply the Paste Inside the Oven
Put on rubber gloves and spread the paste across every interior surface of the oven. Focus extra paste on the floor, back wall, and areas with visible grease stains. Avoid the heating elements and gas igniters. The paste will turn brown as it contacts grease, which means it is working.
Coat the inside of the oven door as well, paying attention to the edges where drips accumulate. Use a toothbrush to push paste into corners and around hinges where grease hides.
Step 4: Wait 12 Hours (Overnight Is Best)
Close the oven door and let the paste sit for at least 12 hours. Overnight timing works perfectly since you apply it after dinner and wipe it out the next morning. The baking soda needs this dwell time to break down carbonized grease and food residue at the molecular level.
Heavily soiled ovens benefit from 24 hours of dwell time. If you see thick black spots that have not softened after 12 hours, reapply fresh paste to those areas and give it another 8-12 hours.
Step 5: Spray Vinegar and Wipe Clean
After the wait, spray white vinegar generously over all the baking soda residue. The mixture will fizz on contact, which helps lift the loosened grime. Let the fizzing action work for 5-10 minutes.
Wipe everything out with damp towels or a wet sponge. Rinse your sponge frequently and keep wiping until no white residue remains. A plastic spatula helps scrape off stubborn spots without scratching the enamel. For the final pass, spray vinegar one more time and wipe with a clean damp cloth.
Cleaning the Oven Racks
While the oven soaks overnight, clean the racks separately. Lay them in a bathtub lined with old towels to protect the finish. Sprinkle baking soda generously over the racks, then spray with vinegar until fizzing. Fill the tub with enough hot water to submerge the racks and add 1/2 cup of dish soap.
Let the racks soak for 4-8 hours. Scrub with a nylon brush or steel wool pad, then rinse and dry completely before reinserting. This method removes baked-on drips that make racks sticky and hard to slide.
Tackling the Oven Door Glass
Make a fresh thin paste of baking soda and water and spread it across the inside of the oven door glass. Let it sit for 30 minutes, then scrub with a non-scratch sponge. For the gap between the glass panes where drips collect, unscrew the door panel according to your owner’s manual or use a straightened wire hanger wrapped in a damp cloth to reach inside.
What About the Self-Clean Cycle?
Most modern ovens include a self-clean function that heats the interior to around 900 degrees Fahrenheit and incinerates residue into ash. It works, but the extreme temperature can damage door gaskets, blow fuses, and produce strong odors that linger for hours. Some manufacturers even recommend against frequent use. Cleaning oven with baking soda avoids all of these risks while delivering comparable results on standard buildup. Reserve the self-clean cycle for truly extreme cases where grease has carbonized into rock-hard layers.
How Often to Deep Clean Your Oven
Most households benefit from a full baking soda cleaning every 3-4 months. If you roast frequently or notice smoke during preheating, clean sooner. A quick monthly wipe-down with a vinegar spray prevents heavy buildup from forming in the first place.
Placing a sheet of aluminum foil or a silicone oven liner on the bottom rack catches drips before they carbonize. This single habit can extend the time between deep cleans to 6 months or longer.
