Your mattress smells musty, feels less fresh than it used to, and you’re wondering if there’s a simple way to refresh it without expensive cleaners or professional services. Learning how to freshen a mattress with baking soda is an effective, budget-friendly solution that works in just a few hours.
Here’s exactly what you’ll discover: A step-by-step method to eliminate odors, absorb moisture, and leave your mattress feeling clean and fresh using just baking soda and a few household items.
Why Baking Soda Works So Well for Mattress Freshening
Baking soda is a natural deodorizer that absorbs moisture and neutralizes acids that cause unpleasant smells. Unlike harsh chemicals, it’s safe for your family and won’t leave behind residue or strong fragrances.
When you freshen a mattress with baking soda, you’re targeting the root causes of odors:
- Body oils and sweat that seep into fabric
- Dead skin cells that accumulate over time
- Moisture trapped in mattress layers
- Spills or accident residue
The alkaline nature of baking soda neutralizes acidic odors while its fine texture helps lift away debris when vacuumed up.

What You’ll Need Before You Start
Gather these simple supplies to freshen a mattress with baking soda effectively:
- 2-3 cups of baking soda (more for king-size mattresses)
- A fine-mesh sieve or shaker container
- Vacuum cleaner with upholstery attachment
- Essential oils (optional, 10-15 drops of lavender or tea tree)
- Clean cloth or paper towels
- 3-8 hours of time for the baking soda to work
You probably already have most of these items at home, making this one of the most accessible mattress cleaning methods.
Step-by-Step Guide: How to Freshen a Mattress With Baking Soda
Step 1: Strip and Prep Your Mattress
Remove all bedding, pillows, and mattress protectors. This is your chance to wash everything in hot water while the mattress treatment works.
Check for any visible stains and spot-clean them first with a damp cloth. Let the mattress air dry completely before applying baking soda – moisture will prevent the powder from working effectively.
Step 2: Apply the Baking Soda Treatment
Sprinkle baking soda evenly across the entire mattress surface. Use your sieve or shaker to ensure even distribution – you want a light, consistent layer covering every inch.
For extra freshening power, mix 10-15 drops of essential oil into the baking soda before sprinkling. Lavender promotes better sleep, while tea tree oil has natural antimicrobial properties.
Don’t forget the sides of your mattress! These areas often get overlooked but can harbor just as many odors.
Step 3: Let Time Do the Work
Allow the baking soda to sit for at least 3 hours, but 8 hours or overnight works even better. The longer you wait, the more odors and moisture the baking soda can absorb.
Open windows or use fans to improve air circulation around the mattress. This helps speed up the deodorizing process and prevents humidity from interfering with the treatment.
If possible, position the mattress in direct sunlight – UV rays naturally kill bacteria and dust mites while the baking soda works.
Step 4: Vacuum Thoroughly
Use your vacuum’s upholstery attachment to remove every trace of baking soda. Work in overlapping strokes, paying special attention to seams, corners, and indentations where powder might hide.
Make several passes over the entire surface. Any leftover baking soda will feel gritty against your sheets and could irritate sensitive skin.
Check the vacuum bag or canister – you’ll be surprised how much debris comes up along with the baking soda!
Advanced Tips to Maximize Results
Target Problem Areas First
Focus extra baking soda on areas where you sleep most often. The head and foot of the bed typically need more attention than the center edges.
If you notice any particular spots that seem to retain odors, give those areas an extra-thick layer of baking soda and let it sit longer.
Combine With Deep Cleaning
While the baking soda works, take advantage of the time to freshen a mattress with baking soda by also cleaning your bed frame, headboard, and surrounding area.
Wipe down surfaces with a microfiber cloth and check for dust bunnies under the bed that might be contributing to allergens.

Make It a Seasonal Routine
Spring and fall are ideal times to freshen a mattress with baking soda as part of your deep cleaning routine. This timing coincides with changing bedding for different seasons.
You don’t need to do this treatment more than 2-3 times per year unless you’re dealing with specific odor issues.
What to Expect: Results and Timeline
Most people notice a significant difference immediately after vacuuming up the baking soda. Your mattress should smell neutral and feel fresher to the touch.
The treatment works effectively on general mustiness and everyday odors. For strong smells like spills or accidents, you might need to repeat the process or combine it with enzyme cleaners.
Don’t expect baking soda to fix structural issues like sagging or worn-out support – this method specifically targets freshness and odor elimination.
Mistakes to Avoid
Never apply baking soda to a damp mattress. Moisture will cause the powder to clump and potentially create paste-like spots that are difficult to remove.
Don’t rush the process – giving the baking soda just 30 minutes won’t provide the deep deodorizing effect you’re looking for.
Avoid using too much baking soda in one application. A light, even layer works better than thick piles that might not vacuum up completely.

When to Try Alternative Methods
If you freshen a mattress with baking soda and still notice persistent odors, consider these additional approaches:
- Steam cleaning for deeper sanitization
- Enzyme cleaners for biological stains and smells
- Professional mattress cleaning for valuable or severely affected mattresses
- Mattress replacement if the bed is very old or damaged beyond freshening
Sometimes combining baking soda treatment with one of these methods gives excellent results.
Maintaining Freshness Between Treatments
Use a quality mattress protector to prevent future odors and stains. This barrier makes regular maintenance much easier and extends the time between deep freshening sessions.
Rotate your mattress every 3-4 months to ensure even wear and prevent moisture buildup in one area.
Keep your bedroom well-ventilated and consider using a dehumidifier if you live in a humid climate.
The Bottom Line on Mattress Freshening
Learning how to freshen a mattress with baking soda gives you an effective, natural way to maintain your bed’s cleanliness without harsh chemicals or expensive services. This simple technique works for most odor issues and takes just a few hours of your time.
The best part? You can do this treatment as often as needed using ingredients you probably already have at home.
