How to Clean an Oven with Baking Soda and Vinegar (No Harsh Fumes)

A greasy oven is one of those chores most people put off for months. The good news is that you don't need a can of fume-heavy oven cleaner to get it clean. Baking soda and white vinegar can lift baked-on grease and burnt spills with almost no scrubbing, as long as you give them enough time to work.

This method works for most standard ovens. If you have a self-cleaning oven, you can still use it, but never spray anything on the heating elements or the gasket (the rubber or fiberglass seal around the door).

What You'll Need

1/2 cup baking soda
2–3 tablespoons water (enough to make a spreadable paste)
White vinegar in a spray bottle
Rubber gloves
A plastic scraper or old spatula
A damp microfiber cloth and a dry one
Dish soap (for the racks)

Step 1: Empty and Prep the Oven

Make sure the oven is completely cool. Remove the racks, thermometer and anything else inside. Scrape out any loose crumbs or burnt bits with a dry cloth or a vacuum hose so the paste can reach the actual grime.

Step 2: Make and Apply the Baking Soda Paste

Mix the baking soda with water until it looks like a thick, spreadable frosting. Wearing gloves, spread the paste over the oven floor, walls and the inside of the door. Use more on the darkest, greasiest spots. Avoid the heating elements and the door gasket.

The paste will turn brown as it touches grease. That's normal and it means it's working.

Step 3: Let It Sit Overnight

This is the step people skip, and it's the most important one. Leave the paste for at least 12 hours. Baking soda is a mild alkali, and over time it softens the fats and carbon that are stuck to the enamel.

Step 4: Clean the Racks While You Wait

Lay an old towel in your bathtub to prevent scratches, place the racks on top, and fill the tub with hot water until the racks are covered. Add about 1/2 cup of dish soap and let them soak overnight too. In the morning, scrub with a brush or a non-scratch sponge and rinse.

Step 5: Wipe and Scrape

The next day, use the damp cloth to wipe away as much paste as you can. For stubborn areas, use the plastic scraper. Don't use a metal scraper, which can scratch the enamel.

Step 6: Spray with Vinegar

Spray white vinegar over any remaining baking soda residue. It will foam slightly as the acid reacts with the leftover baking soda, which helps loosen the last bits. Wipe again with a damp cloth until there is no white film left, then dry with a clean cloth.

Step 7: Clean the Oven Door Glass

For the inside of the glass, apply a thinner layer of the paste, leave it for 20–30 minutes, and wipe it off. For the outside, a little vinegar on a microfiber cloth is enough to remove fingerprints and streaks.

Tips for Keeping Your Oven Clean Longer

Use a baking sheet on the lower rack when cooking anything that might bubble over, like casseroles or pies.
Wipe spills once the oven is cool, before they get baked on again the next time you cook.
Do a light clean every 2–3 months so you never have to deal with years of buildup.

Safety Note

Never mix vinegar or baking soda with commercial oven cleaner, and never combine bleach with vinegar or ammonia. Mixing cleaning products can create toxic fumes. Stick to one method at a time and rinse well between them.

FAQ

Can I use this method on a self-cleaning oven? Yes. Just avoid the door gasket and don't use abrasive pads, which can damage the special coating some self-cleaning ovens have.

How long does the whole process take? About 30 minutes of actual work, plus 12 hours of waiting time.

What if some stains won't come off? Repeat the paste on those spots and let it sit another few hours. Very old carbon stains may lighten but never disappear completely, and that's normal for older ovens.
