By midafternoon, my entryway had that familiar “real life happened here” smell: damp shoes, a dog bed, yesterday’s takeout bag, and a jacket that had clearly survived a rainy commute. I had already opened the door, lit a candle, and sprayed the air. Nothing really lasted.
Then my mom reminded me of her old standby: a tiny jar of baking soda mixed with a few drops of essential oil. She keeps one in the bathroom, one near the laundry hamper, and one in the linen closet. No fancy diffuser. No bulky plug-in. Just a little odor-absorbing jar tucked where smells tend to collect.
I tried it in one room first. Then another. Now I’m using this simple room freshening trick all over the house.
The Simple Room Freshening Trick My Mom Swears By
The method is almost laughably easy. You fill a small jar with baking soda, add a few drops of an essential oil you enjoy, cover the top with a breathable material, and place it where the room needs a little help.
Baking soda helps absorb lingering odors instead of simply covering them up with a heavy fragrance. The essential oil adds a light, clean scent. Together, they make a low-cost DIY air freshener that takes up almost no space.
That last part matters. We’ve all stared at a crowded bathroom counter or stuffed linen closet and wondered where one more thing could possibly go. These little jars fit on a shelf, in a cabinet corner, or behind a basket.
What You Need
- A small jar, ramekin, or recycled glass container
- Baking soda
- Essential oil, such as lemon, lavender, peppermint, eucalyptus, or orange
- A piece of breathable fabric, coffee filter, or paper towel
- A rubber band, twine, or the metal ring from a mason jar lid
- A fork or spoon for stirring
How to Make a Baking Soda Air Freshener Jar
Fill your jar about halfway with baking soda. Add 8 to 15 drops of essential oil, depending on the size of the container and how noticeable you want the scent to be. Stir it gently with a fork to break up any clumps and distribute the oil.
Cover the opening with fabric, a coffee filter, or a paper towel. Secure it with a rubber band or jar ring. That’s it.
Give the jar a little shake every few days to wake up the scent. When it starts smelling flat, stir in a few more drops of oil. Replace the baking soda every month or two, especially in high-odor spots like bathrooms, closets, and laundry areas.
Why This Works Better Than a Quick Spray
Room sprays can be nice for a fast reset before guests arrive. But they usually float through the air for a few minutes, then disappear. If the source of the smell is still there, the room goes right back to normal.
This DIY baking soda freshener works quietly in the background. It is especially helpful in small, enclosed places where odors hang around: drawers, closets, shoe cabinets, bathrooms, and laundry rooms.
It also gives you control. You can keep the scent soft and clean instead of turning your home into a perfume counter.
A Few Things It Will Not Do
Let’s be practical: a baking soda jar is not a substitute for cleaning. If the trash needs to go out, take it out. If towels smell musty, wash and dry them thoroughly. If there is mildew, pet urine, smoke damage, or a persistent sewage-like odor, find and handle the source.
Think of this as the finishing touch after your regular cleaning routine. It keeps the room feeling fresher between deep cleans.
Where I’m Using These Little Freshener Jars Now
1. Near the Entryway Shoe Drop Zone
Shoes are one of the fastest ways to make a small entry smell stale. I keep a small baking soda jar on the lower shelf of our shoe cabinet. It doesn’t take up room, and it helps keep that closed-up shoe smell from greeting us at the door.
Space-saving tip: Use a short, wide jar that can sit behind a basket or inside a cabinet. A small jelly jar works beautifully here.
2. In the Bathroom
The bathroom is where this trick really earned its permanent spot. I place one jar on the back of the toilet or on a shelf, using lemon, eucalyptus, or lavender oil. The scent stays light, but the room feels cleaner.
If your bathroom is tiny, skip the countertop clutter. Set the jar inside an open vanity cabinet or on a high shelf instead.
3. Inside the Linen Closet
Fresh towels can pick up that closed-closet smell, especially when the shelves are packed tight. A small lavender baking soda jar helps keep linens smelling pleasant without spraying fragrance directly onto fabric.
Space-saving tip: Roll towels instead of stacking them, then place the freshener jar in the back corner. You’ll free up shelf space and still get the benefit of the scent.
4. By the Laundry Hamper
Dirty clothes have a way of announcing themselves before laundry day. A freshener jar near the hamper helps a lot, particularly in bedrooms, mudrooms, and small laundry closets.
For this area, I like clean cotton, lemon, or lavender scents. Keep the jar out of reach of children and pets, and make sure it cannot get knocked into the hamper.
5. In the Kitchen Trash Cabinet
This is one of those little home organization habits that makes a bigger difference than you’d expect. Put a small jar near the trash bin, but not where spilled food or liquid can get into it. It helps with those lingering onion, coffee ground, and food-container odors.
Of course, emptying the trash regularly still comes first. No jar can compete with a full bin on a hot day.
6. In Closets and Drawers
A closet packed with coats, blankets, extra bedding, and seasonal clothes can feel stale fast. A compact baking soda jar is a simple fix, especially if you don’t have much airflow.
For drawers, use an even smaller container or make a breathable sachet with baking soda and dried lavender. Keep it upright and secure so there is no chance of powder spilling onto clothing.
7. In the Car
Yes, the car counts. Between wet umbrellas, gym bags, drive-thru meals, and kids’ snacks, cars collect smells quickly. A small covered jar can sit safely in a cup holder or door compartment.
Choose a sturdy container with a secure breathable top. You do not want loose baking soda rolling under the seat during a sharp turn.
Choose the Right Scent for Each Room
You don’t need ten different oils, but matching the scent to the room makes the whole house feel more intentional. Keep it simple. One or two scents used consistently can make your home feel familiar and calm.
- Lemon: Great for kitchens, bathrooms, and entryways
- Lavender: Lovely for bedrooms, linen closets, and bathrooms
- Peppermint: Crisp and refreshing in mudrooms, offices, and laundry spaces
- Eucalyptus: Clean and spa-like for bathrooms
- Orange or sweet orange: Warm, cheerful, and useful in living areas
If you have pets, babies, allergies, or scent-sensitive family members, use fewer drops or skip essential oils entirely. Plain baking soda can still help with everyday odors. Always keep essential oils and DIY freshener jars safely out of reach of children and pets.
Small Habits That Make Rooms Smell Fresh Longer
The jar is helpful, but the best results come from pairing it with a few quick routines. Nothing complicated. Just small resets that stop odors from building up in the first place.
- Open windows for a few minutes when weather allows.
- Hang damp towels and bath mats so they can dry fully.
- Empty small trash cans before they are overflowing.
- Wash pet bedding regularly.
- Let shoes air out before putting them into a closed cabinet.
- Keep laundry moving instead of letting damp clothes sit in the washer.
- Wipe refrigerator shelves and trash cabinet interiors once in a while.
- Store extra blankets and seasonal textiles in clean, dry containers.
These are the unglamorous little tasks that make a house feel fresher. And honestly, they are usually easier than trying to cover a stubborn smell later.
Make It Pretty Without Adding Clutter
A DIY air freshener does not need to look homemade in a messy way. If it is sitting out in the open, use a small jar that matches your space: clear glass for a clean look, amber glass for a cozy feel, or a ceramic container for a softer style.
You can also label the bottom with the scent and the date you made it. That way, you know when it is time to refresh the baking soda instead of wondering why the jar has stopped working.
For a more organized setup, make several jars at once and store the extras in a small bin with your cleaning supplies. When one needs replacing, you can grab a fresh one in seconds.
FAQ: DIY Baking Soda Room Fresheners
How long does a baking soda air freshener last?
Most jars stay effective for about four to eight weeks. Stirring the baking soda and adding a few more drops of essential oil can extend the scent, but replace the baking soda when it seems damp, clumpy, or no longer helps with odors.
Can I use fragrance oil instead of essential oil?
Yes, but use it sparingly. Fragrance oils can be much stronger than essential oils. Start with just a few drops, then add more only if needed.
Does baking soda really remove room odors?
Baking soda can help absorb some everyday odors in small spaces, especially closets, cabinets, bathrooms, and near hampers. It works best alongside regular cleaning, fresh air, and removing the actual source of bad smells.
Can I leave an open bowl of baking soda in a room?
You can, but a covered jar with a breathable top is usually neater and safer. It keeps dust, spills, curious pets, and little hands out of the baking soda.
What should I do with the old baking soda?
Once it has done its job, you can sprinkle it into the trash before taking the bag out or use it to scrub a sink or trash bin, as long as it has not been contaminated. Then rinse the jar and make a fresh batch.
I love a home trick that is inexpensive, useful, and easy to tuck away. My mom’s little baking soda jar is not flashy, and that is exactly why it works so well. Make one for the room that needs it most, see how it feels after a week, and don’t be surprised when you start placing them everywhere too.
