How to Clean an Oven Without Harsh Chemicals

Commercial oven cleaners work fast, but many have strong fumes that linger in your kitchen. Baking soda, vinegar and a bit of patience do the same job with ingredients you probably already own.

Updated October 2026

What you need

• 1/2 cup baking soda (more for very dirty ovens)
• 3 to 4 tablespoons water
• White distilled vinegar in a spray bottle
• Liquid dish soap
• Rubber gloves
• Plastic scraper or old plastic card
• Non-scratch sponge and several damp cloths or microfiber towels
• An old towel or bath mat (for soaking racks in the tub)

Total hands-on time is about 45 minutes, spread across two days because the paste needs to sit.

How to clean an oven with baking soda and vinegar

This method works on standard ovens and on self-cleaning ovens when you would rather skip the high heat cycle.

1. Turn the oven off and let it cool completely. If you have a gas oven, make sure the burner is off. Never apply paste to a warm oven.
2. Remove the racks and anything else inside. Take out the thermometer, pizza stone and any foil liners. Set the racks aside to soak (see below).
3. Scrape loose debris. Use a plastic scraper to knock off burnt crumbs and chunks. Sweep them out with a damp paper towel or a handheld vacuum.
4. Mix the paste. Combine 1/2 cup baking soda with about 3 tablespoons of water. Add water a little at a time until it is spreadable, like frosting.
5. Spread it everywhere that is dirty. Wearing gloves, coat the bottom, sides, back and inside of the door. Pile it thicker on greasy spots. Avoid the heating elements, the gas burner opening and any fan in a convection oven.
6. Let it sit at least 12 hours. Overnight is ideal. The paste will turn brown as it absorbs grease.
7. Wipe out the paste. Use a damp cloth to wipe away as much as you can. Use the plastic scraper on stubborn patches.
8. Spray with vinegar. Mist any remaining white residue with vinegar. It will foam as it reacts with the baking soda, loosening the film.
9. Do a final wipe. Wipe with a clean damp cloth, rinsing often, until no residue remains. Dry with a towel.
10. Replace the racks and run the oven briefly. Heat it to 200°F for 10 to 15 minutes to dry everything out.

What if spots are still stuck after the first round?

Reapply a thick dab of paste to those areas only, spray lightly with water to keep it moist, and give it a few more hours. Repeating is easier on your oven than aggressive scrubbing.

How to clean oven racks without chemicals

Racks are often the dirtiest part. A long soak does most of the work.

1. Lay an old towel in your bathtub to protect the finish from scratches.
2. Place the racks on the towel and fill the tub with the hottest tap water you have, enough to cover them.
3. Add about 1/2 cup of dish soap and 1/2 cup of baking soda, and swish to dissolve.
4. Soak for at least 4 hours or overnight.
5. Scrub with a non-scratch sponge or brush, paying attention to the corners.
6. Rinse, dry thoroughly and slide back into the oven.

No tub? Use a large utility sink, a big plastic storage bin, or a heavy-duty trash bag placed outside.

How to clean the oven door glass

The inside of the oven door collects brown splatters that make it hard to check on food.

1. Mix a thick paste of baking soda and a little water.
2. Spread it over the cool glass and let it sit 20 to 30 minutes.
3. Wipe with a damp microfiber cloth, using a plastic scraper on stuck spots.
4. Finish with a spray of vinegar and buff dry for a streak-free shine.

What about grime between the glass panes?

Many oven doors have two layers of glass, and drips can get between them. Some doors can be removed or opened for cleaning, but steps vary by model. Check your owner’s manual before taking anything apart.

How long does each method take?

Job	Hands-on time	Waiting time	Best for
Baking soda and vinegar deep clean	30 to 45 minutes	12 hours or overnight	Heavy, baked-on grease
Oven racks soak	15 minutes	4 hours to overnight	Sticky, browned racks
Door glass	10 minutes	20 to 30 minutes	Splatters on the window
Steam clean (bowl of water)	10 minutes	30 minutes plus cooling	Light grime and quick refreshes
Weekly wipe	2 to 5 minutes	None	Keeping a clean oven clean

Can you steam clean an oven?

Yes, for light grime. Steam softens fresh spills so they wipe away more easily.

1. Fill an oven-safe dish with about 2 cups of water and 1/4 cup of vinegar or the juice of one lemon.
2. Place it on the middle rack and heat the oven to 450°F for 30 minutes.
3. Turn the oven off and let it cool until it is safe to touch.
4. Wipe down the interior with a damp cloth.

Steam will not remove thick, carbonized grease, but it is a good monthly refresh between deep cleans. If your oven has a built-in steam clean setting, follow the manual instead.

Is the self-cleaning cycle a good alternative?

The self-clean cycle burns residue to ash at very high temperatures. It uses no cleaners, but it does have trade-offs.

• It can produce smoke and strong odors, so open windows and run the range hood.
• The high heat is hard on some oven components, which is why many people prefer the baking soda method for routine cleaning.
• Fumes from the cycle are a known hazard for pet birds, so move birds to a well ventilated room far from the kitchen.
• Remove racks first unless your manual says they can stay in.

What should you avoid when cleaning an oven?

• Do not mix bleach with vinegar or ammonia. These combinations release toxic gases. Stick with baking soda, vinegar and dish soap.
• Do not use steel wool on enamel or glass. It scratches the surface, and scratches hold onto grease later.
• Keep paste and water away from heating elements and gas ports. Moisture there can cause problems the next time you heat the oven.
• Do not use commercial cleaners on self-cleaning oven interiors unless your manual says they are safe. Many manufacturers warn against it.
• Wear gloves. Even mild cleaners and baked grease can irritate skin after a long session.

How often should you clean your oven?

Most households do well with a deep clean every three to six months, plus a quick wipe of fresh spills once a week. If you roast or bake often, you may need a deep clean every two to three months.

A few habits stretch the time between deep cleans:

• Set a sheet pan on the rack below pies, casseroles and anything likely to bubble over.
• Sprinkle salt on fresh spills while the oven is still warm, then wipe them once it cools.
• Cover roasting dishes when you can to reduce splatter.

Frequently asked questions

How long should baking soda sit in the oven?

Leave the paste for at least 12 hours, and overnight is ideal. That gives it time to soften baked-on grease. For a lightly soiled oven, a few hours can be enough.

Is it safe to use the oven right after cleaning with baking soda?

Yes, once all residue is wiped out. Run the oven at 200°F for 10 to 15 minutes to dry it, and you may notice a faint smell the first time you cook, which fades quickly. Leftover baking soda is not harmful, but it can smoke slightly if a thick layer remains.

Can you clean an oven with just vinegar?

Vinegar alone helps with light grease and steam cleaning, but it struggles with thick, baked-on residue. It works best paired with baking soda, which does the heavy lifting while vinegar helps lift and rinse the leftover film.

How do you get burnt grease off the bottom of an oven?

Scrape off loose pieces with a plastic scraper, then apply a thick baking soda paste and leave it overnight. Spray with vinegar, wipe and repeat on any stubborn patches. Avoid metal scrapers that can damage the enamel.

Can you use the baking soda method in a self-cleaning oven?

In most cases, yes. Many people prefer it to the high heat cycle. Avoid scrubbing hard, keep moisture off any exposed elements, and check your owner’s manual for model-specific guidance.

A clean oven makes your kitchen smell better and your food taste better, since old grease is not smoking every time you preheat. Set it up the night before, and the wipe out the next day takes less time than you expect.
