How to Clean Baked-On Grease From Oven Glass and Door Panels

Baked-on grease on oven glass is one of those jobs that looks impossible until you know the trick. The glass darkens, visibility into the oven drops, and the whole appliance starts looking neglected even if everything else is clean. The problem isn't that the grease is permanent—it's that you've been trying to dissolve it when you should be letting chemistry do the work for you. A thick paste of baking soda and water breaks the bond between grease and glass without requiring aggressive scrubbing that risks scratching. This is a weekend project that takes maybe thirty minutes of actual work spread across two days, and the payoff is a kitchen that feels instantly cleaner.

1. Clear the Glass First. Open the oven door fully and sweep out any loose crumbs, ash, or debris from the bottom using a small brush or vacuum attachment. Wipe the glass with a dry cloth to remove dust. This prevents grit from scratching the glass when you scrape later.
2. Mix Your Weapon. Pour three tablespoons of baking soda into a small bowl and add one tablespoon of water. Stir until you have a thick, spreadable paste—not runny, not dry. The paste should stick to the glass without dripping. Add another half tablespoon of water if it's too thick, or more baking soda if it's too thin.
3. Coat It Thick. Using a plastic scraper or old credit card, spread the baking soda paste over the entire glass panel in a thick, even layer. Work from top to bottom. Cover all the visible grease marks and darkened areas. The paste should be thick enough that you can't see the glass underneath. Pay extra attention to the corners where grease tends to accumulate.
4. Patience Wins Here. Close the oven door and leave the paste untouched for 12 to 24 hours. The alkalinity of the baking soda slowly breaks down the bond between the grease and glass. Overnight is the minimum; longer is fine. Don't be tempted to scrub early—the paste needs time to work.
5. Wake the Paste Up. The next day, spray the entire paste-covered glass with water from a spray bottle until it's wet but not dripping. The paste will soften and reactivate. Wait five minutes for the water to soak in.
6. Scrape With Purpose. Using a plastic scraper or old credit card held at a low angle (about 30 degrees), push the softened paste away from the glass. Work from top to bottom in steady strokes. The paste should come away in clumps. For very stubborn spots, re-wet that area and wait another two minutes before scraping.
7. Deploy Last Resort. If grease spots remain after scraping with plastic, hold a razor blade at a very shallow angle (nearly flat against the glass) and gently push forward. Let the blade weight do the work—don't press hard. Test a small spot first. This removes spots that dried paste alone won't budge, but it requires a light touch.
8. Wipe It Down. Once the paste and grease are scraped away, wipe the entire glass surface with a damp cloth or sponge to remove any remaining paste residue and loose grease. Go over it twice if needed. The glass should feel smooth and free of grit.
9. Dry and Shine. Use a clean, dry cloth or microfiber towel to dry the glass completely. This prevents water spots and shows off your clean glass. If you used a razor blade, dry the area immediately to prevent rust spots from forming on any metal edges around the glass.
10. Polish the Frame. While you're at it, wipe down the metal frame around the glass panel and the door handle with a damp cloth. Grease often creeps onto the frame, and cleaning it now makes the whole door look sharp. Use an old toothbrush for the crevices around the hinges.
11. Finish With Sparkle. For a final shine, spray the dry glass lightly with white vinegar and wipe with a clean, dry cloth. The vinegar cuts any remaining film and leaves a streak-free finish. This step is optional but makes the difference between clean and shiny.
