How to Deodorize a Mattress: 6 Fresh Tips
Is your bed starting to smell unusual? If so, now is the right time to learn how to deodorize a mattress.
Mattresses endure a lot of wear and tear. We sweat, shed skin cells, and dust collects over time. Even with regular bedding washes, body oils and allergens can seep into the mattress, leading to unpleasant odors. Suboptimal conditions can disrupt sleep quality and trigger allergies if moisture builds up.
Fortunately, if your mattress has developed an odor, there are several effective methods to deodorize it. Here are six DIY approaches to freshen your mattress:
How to Deodorize a Mattress
Deodorizing involves eliminating odors from various sources, including stains, spills, allergens, and dust mites. It is recommended to deodorize your mattress at least twice a year. If you experience frequent night sweats, more frequent deodorizing may be necessary.
Begin by removing all bedding. This would be a good time to wash them. Next, gather your cleaning supplies.
1. Baking Soda
Baking soda is an effective and natural deodorizer.
- Sprinkle a layer of baking soda evenly across the mattress using a sifter.
- Allow it to sit for two hours so it can absorb odors.
- Use a handheld vacuum to remove the baking soda.
Best for: Neutralizing odors
2. Essential Oils
To enhance the scent of your mattress, add a few drops of essential oil to the baking soda before applying it. Here are some calming essential oils you might consider:
- Lavender
- Chamomile
- Jasmine
- Rose
- Peppermint
- Lemon
Best for: Adding fragrance
3. Cornstarch
Mix cornstarch with baking soda to absorb body oil and odors.
- Apply the mixture like baking soda, let it sit for around two hours, and then vacuum it up.
Best for: Absorbing body oil
4. Vinegar
For smelly stains, vinegar can be effective.
- Mix equal parts distilled white vinegar and water in a spray bottle.
- Lightly spritz this mixture on the stained areas without soaking them.
- Let it air dry completely.
Be aware that the vinegar’s smell may linger, so allow proper ventilation.
Best for: Removing dirt and stains
5. Laundry Detergent
For targeted cleaning, a gentle laundry detergent can be applied.
- Create a paste by mixing laundry detergent with baking soda, spread it over the stain, and then scrape it off after it dries.
Best for: Spot cleaning stains
6. Vacuum
Use a vacuum cleaner, particularly one with an upholstery attachment, to remove dust, dirt, and allergens.
- Focus on crevices and the sides of the mattress for a thorough clean.
Best for: Removing dust, dirt, pet dander, and hair

Other Ways to Keep Your Mattress Fresh
In addition to deodorizing, these tips can help prevent future odors.
Use a Mattress Protector
Covering your mattress with a protector can shield it from stains and spills. Regular cleaning of the protector will further enhance the mattress's longevity and upkeep.
Air Out the Room
Regularly airing out your bedroom can reduce moisture buildup. Strip the bedding, open the windows, and prop the mattress for fresh air circulation.
Sunlight
Exposing the mattress to sunlight helps eliminate odors and prevent staining. If possible, place the mattress outside periodically.
Regular Cleaning
Cleaning your mattress regularly is essential. For deep cleaning, consider professional help, but you can handle small stains yourself with an enzyme-based cleaner.
Clean the Box Spring or Foundation
Don’t forget to clean the box spring. Dust and dirt can accumulate there as well.
Wash Your Bedding
Regular washing of bedding is crucial. Here’s a guideline for how often to wash various parts of your bed:
| Item | Frequency |
|---|---|
| Mattress | Every 6 months |
| Duvet | Every 3-6 months |
| Quilt | Every 3-6 months |
| Sheets | Weekly |
| Pillows | Every 6 months (every 2–3 months for memory foam) |
| Pillowcases | Weekly |
