How to Remove Burnt Grease from an Oven
Spread a paste of baking soda, dish soap, and water over greasy oven walls and glass (avoiding heating elements), let sit overnight for 8–12 hours, mist with white vinegar, and wipe clean.
Context
Conditions that change the method
- Delicate surface — Avoid applying cleaning paste to gas igniters, electric heating elements, thermostat probes, or rubber door gaskets.
Ensure power is off and avoid caustic fumes
Always ensure oven controls are turned off and the appliance is stone cold before cleaning. Avoid caustic aerosol lye cleaners in poorly ventilated kitchens. If cleaning pastes enter eyes or irritate skin, flush immediately with clean water.
What you need
- Baking soda (1/2 cup)
- Liquid dish soap (1 tablespoon, cuts caramelized grease)
- Distilled white vinegar in a spray bottle
- Water
- Microfiber cloths and non-scratch scouring sponge
- Ensure the oven is completely cold, remove all interior wire racks and thermometer probes, and scrape away loose carbon flakes with a silicone spatula.
- Mix 1/2 cup baking soda, 1 tablespoon dish soap, and 2 to 3 tablespoons water in a bowl to make a spreadable, thick degreasing paste.
- Spread the paste over greasy oven side walls, bottom pan, back panel, and interior glass window, keeping paste off heating elements and gas burner tubes.
- Allow the paste to sit for 8 to 12 hours (or overnight) as the alkaline soda and soap break down polymerized, hardened cooking oils.
- Wipe out the dried paste and softened brown grease using a damp microfiber cloth, rinsing the cloth frequently in warm water.
- Spray remaining white residue lightly with distilled white vinegar; as it foams gently, wipe the enamel and glass surfaces completely clean and buff dry.
What to avoid
- Never coat electric heating elements or gas pilot assemblies with cleaning pastes.
- Avoid green heavy-duty scouring pads or razor scrapers on oven glass windows, which weaken tempered glass and risk thermal shattering.
- Do not run the high-heat self-clean cycle when heavy grease pools on the bottom, as this poses extreme fire hazards.
Products
What to use
- Baking sodaA mild alkali that makes a paste for grout lines. It lifts film with light abrasion. Do not mix it with vinegar as a cleaning trick — the fizz is the two canceling each other out.
- Dish soapA mild alkaline soap that cuts grease and soap film. Dilute it in warm water. It is a cleaner, not a disinfectant claim, and it is not a substitute for a product labeled for grout mineral deposits.
- Distilled white vinegarA mild acid useful for mineral deposits and some soap films on glass and other acid-safe surfaces. Never mix it with bleach or ammonia. It is a method, not a disinfectant claim.
- Microfiber clothA reusable cloth that lifts film and leftover moisture without scratching glass. Use a clean face of the cloth as residue comes off.

FAQ
Questions people ask
- How do I clean heavy burnt grease off the wire oven racks?
- Place an old towel in the bottom of a bathtub, lay the racks on top, sprinkle with baking soda and dish soap, fill with very hot water, let soak for 4 to 6 hours, and scrub with a non-scratch sponge.
- Why shouldn't I use the self-cleaning cycle instead of baking soda?
- The self-cleaning cycle heats the oven to over 900°F (500°C), which creates toxic carbon and enamel smoke fumes, damages sensitive electronic control boards, and can blow thermal fuses.
