How to Get Rid of Smell in Mattress

Tools:

- E-Cloth
- Vacuum with upholstery attachment
- Baking soda
- White vinegar
- Spray bottle

Step 1: Air It Out

Strip all bedding off the mattress and, if possible, take the mattress to a well-ventilated area or open window to let fresh air circulate.

Step 2: Vacuum Thoroughly

Use a vacuum with an upholstery attachment to cover the mattress surface. This helps remove dust, dirt, and any hidden particles that might be trapping odors.

Step 3: Apply Baking Soda

Sprinkle a generous layer of baking soda evenly across the entire mattress.
Let it sit undisturbed for several hours (or overnight) so the baking soda can absorb odors effectively.
After the waiting period, vacuum the mattress again to remove all the powder.

Step 4: Use a Vinegar Mist

Mix equal parts water and white vinegar in a spray bottle.
Lightly mist the surface of the mattress without soaking it—too much moisture can lead to mildew.
Allow the mattress to air dry completely. The vinegar smell will fade as it dries, taking unwanted odors with it.

Step 5: Repeat if Necessary

If the smell lingers after the first round, repeat the baking soda and vinegar mist steps as needed.
Always ensure the mattress is completely dry before putting the bedding back on to prevent future odor issues.

Safety Precautions

Ensure proper ventilation: Always clean your mattress in a well-ventilated area to avoid inhaling dust, baking soda, or vinegar fumes.
Avoid over-wetting: When using the vinegar mist, do not soak the mattress—excess moisture can cause mold and mildew growth.
Test cleaning solutions: Before applying vinegar or any cleaner, spot test on a small, hidden area to check for fabric discoloration or damage.
Use protective gear: Wear gloves and a mask if you have sensitive skin or allergies to dust or cleaning agents.
Keep children and pets away: Ensure the mattress and cleaning supplies are out of reach during the cleaning and drying process.
Allow full drying: Never cover or use the mattress until it is completely dry to prevent bacteria and odor buildup.

How to Maintain Cleanliness How to Get Rid of Smell in Mattress: Extra Tips

Vacuum Regularly to Remove Dust & Allergens

Run a vacuum with an upholstery attachment over your mattress weekly to remove dust, dead skin, and allergens that build up over time.
This simple step also helps in minimizing odors by reducing the organic matter that bacteria thrive on.

Title

Sprinkle Baking Soda Overnight

Evenly distribute baking soda across the surface of your mattress to absorb trapped odors.
Let it sit for at least 8 hours or during the day, then vacuum thoroughly to remove the powder along with loosened smells.

Title

Spot Clean Stains Promptly

Address spills and stains immediately using a mild detergent mixed with water to prevent stains from setting in.
Gently dab the area without oversaturating the mattress, ensuring the cleaning solution eliminates any odor-causing residues.

Title

Air Out the Mattress Regularly

Set aside time to expose your mattress to fresh air by opening windows or moving it near a window, especially on sunny days.
This not only reduces moisture build-up but also helps dissipate any lingering odors, keeping your sleeping environment fresh.

Common Mistakes When Cleaning How to Get Rid of Smell in Mattress

Skipping Small, Hard-to-Reach Spaces

Neglecting corners, behind furniture, or tight nooks can leave dust and allergens lingering in the room.
Use narrow attachments on your vacuum or a slim duster for these often-missed zones.

Ignoring the Importance of Drying Surfaces

Leaving surfaces damp after cleaning can create streaks or encourage mold growth, especially in humid areas.
Always follow up with a dry, clean cloth to wipe down surfaces and ensure a polished, dry finish.

Reusing Dirty Cloths Without Washing

Using the same unwashed cloth spreads dirt and bacteria instead of removing them.
Rinse and launder your cleaning cloths frequently between uses for maximum effectiveness.

How Often to Clean How to Get Rid of Smell in Mattress

Recommended Mattress Cleaning Frequency for Odor Control

Every two weeks: Regularly vacuuming your mattress helps remove dust, skin cells, and other debris that can trap odors over time.
Every six months: A deeper cleaning every half-year aims to tackle accumulated sweat, body oils, and moisture that contribute to stubborn smells.
As needed: If you’ve had a spill or notice an unpleasant odor emerging, clean those areas immediately. Adjust your schedule temporarily to prevent further odor buildup.
Why this frequency matters: Consistent upkeep stops bacteria and allergens from settling deep in the fabric, creating not just a fresher mattress but a healthier sleeping environment overall.
