A dirty oven sneaks up on you. One spilled casserole, a few roasted vegetables and a pizza that dripped cheese, and suddenly every preheat comes with a faint smell of smoke.
Commercial oven cleaners work, but many of them have strong fumes that linger in the kitchen. If you would rather avoid that, it is easy to clean an oven naturally with baking soda, white vinegar and warm water. It takes some waiting time, but very little effort.
Here is the full method, from the racks to the glass door.
What You Will Need
- Baking soda (about 1/2 cup for an average oven)
- Water
- White vinegar in a spray bottle
- A small bowl and a spoon or spatula for mixing
- Rubber gloves
- A plastic scraper or an old plastic card
- Non scratch sponges and microfiber cloths
- A bucket or a large sink for the racks
- An old towel
Everything on this list costs a few dollars, and most of it is probably already in your kitchen.
Before You Start: Safety Notes
- Make sure the oven is completely cool and turned off. For an electric oven, it is wise to switch it off at the breaker if you will be working near the elements. For a gas oven, make sure the gas is off.
- Never mix vinegar and baking soda with bleach, and never combine bleach with ammonia or vinegar. If you have used a commercial cleaner in the oven recently, wipe it out thoroughly with water before using the natural method.
- Do not spread paste on the heating element, the gas outlet, the thermostat sensor or the door gasket. Work around them.
- Open a window for ventilation, even with natural ingredients. Old burnt residue can release smoke and smells when you first heat the oven afterward.
- Test a hidden spot if your oven has a special enamel or coated finish, and check your manual for any cleaning restrictions.
Step by Step: Cleaning the Oven Interior
1. Empty the Oven
Remove the racks, any thermometer, pizza stone or pans. Set the racks aside for later.
2. Scrape Off Loose Debris
Use a plastic scraper or a dry cloth to remove crumbs and any burnt pieces that come away easily. Vacuum the crumbs if there are many.
3. Make the Baking Soda Paste
In a small bowl, mix about 1/2 cup of baking soda with 2 to 3 tablespoons of water. Add water a little at a time until you have a spreadable paste, similar to thick frosting.
4. Coat the Inside
Wearing gloves, spread the paste over the bottom, sides and back of the oven. Use more on greasy, dark spots. The paste may turn brown as it sits on grease, which is normal.
5. Let It Sit Overnight
Close the oven door and leave the paste for at least 12 hours. Overnight is ideal. This waiting time does most of the work, softening baked on grease so you do not have to scrub hard.
6. Wipe Out the Paste
The next day, use a damp cloth and the plastic scraper to remove the dried paste. Rinse the cloth often. Take your time in the corners.
7. Spray With Vinegar
Spray a light mist of vinegar wherever you still see baking soda residue. It will foam gently, which helps lift the last bits. Wipe again with a damp cloth.
8. Final Rinse
Wipe the whole interior once more with clean water and a fresh cloth, then dry with a towel. Leave the door open for 30 minutes to air out.
How to Clean Oven Racks
Racks are often the dirtiest part. Here is the simplest way to tackle them:
- Line the bathtub or a large sink with an old towel to protect the surface from scratches.
- Place the racks inside and sprinkle them generously with baking soda.
- Spray the racks with vinegar and let the foaming settle.
- Fill with hot water until the racks are fully covered, then add a few drops of dish soap.
- Soak overnight.
- Scrub with a non scratch sponge or a stiff brush, rinse well and dry completely before putting them back.
If the racks will not fit in your tub, use a large plastic storage bin outdoors, or wrap them in an old towel soaked with the same mix.
How to Clean the Oven Door Glass
The glass shows every drip, but it cleans up nicely:
- Spread a thin layer of baking soda paste on the inside of the glass.
- Let it sit for 20 to 30 minutes.
- Wipe it off with a damp microfiber cloth.
- Finish with a light mist of vinegar and a dry cloth for a streak free shine.
If there are drips trapped between the panes of glass, check the manual. Some doors can be taken apart for cleaning, but many cannot, and forcing them can damage the seal.
Tips to Keep Your Oven Cleaner Longer
- Use a sheet pan on the lower rack when baking anything that might bubble over, such as pies, lasagna or casseroles. Do not cover the oven floor with foil, as it can block air flow and damage some ovens.
- Wipe small spills once the oven cools. A fresh spill takes seconds. A spill that has been baked ten times takes an evening.
- Do a light clean every month and a full overnight clean every three to four months, or before the holidays.
- Check for smoke when preheating. If you smell burning, it is time for a clean.
What About the Self Cleaning Setting?
Many ovens have a self cleaning cycle that heats the interior to very high temperatures to burn residue to ash. It can work well, but it produces smoke and strong smells, and it makes the oven extremely hot for several hours. If you use it, remove the racks first unless the manual says otherwise, open windows, and keep pets (especially birds, which are sensitive to fumes) out of the area.
The natural method is a gentler option for regular cleaning, and you can always use it between self cleaning cycles.
Wrapping Up
Cleaning an oven naturally takes patience more than effort. A simple paste of baking soda and water does the heavy lifting overnight, vinegar takes care of the residue, and a monthly wipe keeps the grime from coming back.

Quick Questions
How long does it take to clean an oven naturally?
The hands on time is about 30 to 45 minutes total, split across two days. The paste needs at least 12 hours to sit, so plan to start in the evening.
Can I use this method on a self cleaning oven?
Usually yes, but check your manual. Some self cleaning ovens have special interior coatings that should only be wiped with water.
Why does my oven still smell after cleaning?
Small amounts of residue may burn off the first time you heat the oven. Run it empty at a moderate temperature for 15 to 20 minutes with a window open to clear it.
Can I put oven racks in the dishwasher?
Many manufacturers advise against it because it can dull the finish and the racks may not fit. Soaking in the tub is safer.
