Deep Clean Your Oven Interior and Glass Door

Oven cleaning is the kind of job nobody looks forward to, but a truly clean oven actually cooks better—heat circulates more evenly, and you can actually see what's happening inside. The interior and glass door trap grease, burnt food particles, and carbon buildup that only gets worse with time. A deep clean doesn't require harsh chemical fumes or a professional; it just requires patience and the right approach. Done well, your oven will look new again, and you'll understand why preventive cleaning between deep cleans becomes worth the effort.

  1. Remove and soak the racks. Pull out the oven racks completely. Fill your bathtub with hot water and add a cup of baking soda, then submerge the racks. Let them soak for at least 4 hours or overnight. This softens the baked-on grime so you won't have to scrub as hard later.
  2. Make and apply the cleaning paste. Mix a half-cup of baking soda with three tablespoons of water to form a spreadable paste. Spread this paste thickly across the entire oven interior, avoiding heating elements. Focus on corners, the floor, and sides where buildup accumulates. You want a visible layer that's roughly a quarter-inch thick.
  3. Let the paste work overnight. Close the oven door and leave the paste to sit for 12 to 24 hours. The baking soda will slowly break down burnt carbon and grease without any scrubbing required. This wait time is what makes the difference between hard scrubbing and easy removal.
  4. Scrape out the dried paste. Open the oven and use a plastic scraper or old credit card to push the dried paste toward the center of the oven floor. Work systematically from top to bottom so gravity helps move debris downward. Don't use metal scrapers on the oven interior, as they can damage the finish.
  5. Wipe down the interior with vinegar. Spray white vinegar onto the remaining paste residue—it will fizz and help lift the last bits of baking soda. Use a damp cloth or sponge to wipe everything clean. You may need two or three passes. Once the interior is clear, dampen a cloth again and do a final wipe to remove any remaining powder or vinegar smell.
  6. Tackle the glass door with a razor blade. Hold a single-edge razor blade at a 45-degree angle against the glass and scrape away burnt spots and buildup. Work slowly from top to bottom in overlapping strokes. The goal is to remove carbon without gouging the glass. Once you've scraped loose debris, spray vinegar on the glass and wipe with a microfiber cloth.
  7. Scrub and rinse the racks. Remove the soaked racks from the bath and use a stiff brush or scrub pad to remove remaining buildup. Rinse thoroughly under running water. For stubborn spots, reapply baking soda paste and let sit another hour. Dry the racks completely before returning them to the oven.
  8. Replace racks and final inspection. Slide the clean racks back into the oven, making sure they sit evenly in their grooves. Do a final walk-around: wipe any remaining vinegar smell from the glass, check that the interior is completely dry, and close the door. Your oven is now ready for regular cooking.
