We spend about a third of our lives sleeping on a mattress. Yet many of us rarely think about how to deep clean a mattress. Okay, here’s the brutal truth—over time, our mattresses collect dust, sweat, dead skin cells, and other allergens that can affect our sleep quality, health, and overall aging experience.
A regular deep cleaning can extend the life of your mattress and create a healthier sleeping environment by enabling you to breathe clean air while you sleep. This step-by-step guide will walk you through the best way to clean a mattress.
Why Regular Mattress Cleaning Matters
Before diving into the cleaning process, it’s worth understanding why keeping your mattress clean is so important.
A typical mattress can harbor millions of dust mites. That should be gross enough but consider that those mites are also producing waste every day, which can become airborne allergens that we breathe in during sleep.
Additionally, body oils, sweat, and spills can seep into mattress fibers over time. These substances can cause odors and create an unhealthy sleeping environment overall.
Regular cleaning helps:
- Reduce allergens that trigger asthma and allergies
- Eliminate odors from sweat and body oils
- Remove stains from spills and accidents
- Extend the lifespan of your mattress
- Improve overall sleep quality
Mattress Deep Cleaning Essentials
“I usually wear a dust mask whenever I initiate a mattress deep cleaning. Why? Two reasons actually—first I simply feel better about it. While it may only be psychological, I know if I’m not wearing one, I end up sneezing throughout the whole process. Secondly, I seem to have a large number of them left over from the pandemic—and to be honest I just got in the habit of wearing one during cleaning activities—especially if it involves dust.”
Before you begin, gather these necessary items:
- Vacuum cleaner with upholstery attachment
- Mild dish soap
- Warm water
- Clean cloths
- Baking soda
- Spray bottle
- Fan (optional)
- Stain remover (optional)
How to Deep Clean a Mattress at Home
Step 1: Strip the Bed
Start by removing everything from your mattress. Take off all sheets, pillows, mattress covers, and toppers. This gives you full access to the mattress surface. Take the opportunity to wash all bedding in hot water (130°F or 54°C) to kill dust mites.
“Hot water is more effective at removing allergens than cold or warm water.”
Make sure to check care labels on your bedding. Some materials might require special washing instructions. While your bedding washes, you can move on to the next steps of the mattress cleaning process.
Even the cleanest-looking mattress can be home to some unpleasant and invisible guests. Here’s a breakdown of what might be hiding beneath the surface and how to deal with it:
| Unwanted Guest | Source | Simple Solution |
|---|---|---|
| Dust Mites | Dead skin cells, bedding | Wash bedding in hot water weekly, use HEPA vacuum |
| Pet Dander & Hair | Pets sleeping on the bed | Keep pets off the bed, use duct tape trick |
| Sweat & Body Oils | Natural perspiration while sleeping | Deodorize with baking soda, add mattress protector |
| Odors & Bacteria | Spills, trapped moisture, dust buildup | Air out, use vinegar spray, increase ventilation |
Step 2: Vacuum the Surface Thoroughly
Vacuuming is a crucial step when you deep clean a mattress. Use a vacuum with an upholstery attachment, preferably one with a HEPA filter to trap the smallest particles. The HEPA filter prevents dust and allergens from being released back into the air.
Take your time during this step. Move the vacuum slowly across:
- The top surface of the mattress
- Along all seams and edges
- The sides of the mattress
- Underneath, if you can access it
Slow, methodical vacuuming helps lift dust and allergens trapped deep in the fabric. Pay special attention to those thick seams and crevices where dust and debris collect. These areas often harbor the most allergens.
Step 3: Spot Clean Any Stains
After vacuuming, inspect your mattress for stains. Different types of stains may require different treatments, but a gentle approach works best for most situations.
How to Spot Clean a Mattress:
- Mix a small amount of mild dish soap with warm water
- Moisten a clean cloth with the soapy solution
- Press the moist cloth onto the stain—never rub, as this can push the stain deeper
- Do not saturate the stained area, mold thrives in moist environments
- Rinse by blotting with a fresh, damp cloth
- Blot dry with a towel to remove as much moisture as possible
For tougher stains, you might need stronger solutions:
- Biological stains: Try an enzyme cleaner designed for mattresses
- Odor problems: A vinegar solution (equal parts white vinegar and water) can help neutralize odors
TIP: Always test any cleaning solution on a small, hidden area of the mattress first to make sure it doesn’t damage the fabric.
“Got an old box of baking soda you’re about to toss? Maybe it’s the one that’s been hiding at the back of the fridge on deodorizing duty for the last few months. Here’s a money-saving tip: hold onto it for your next mattress deep-cleaning day. You’ll freshen up your bed and stretch your budget at the same time—a win-win!!”
Step 4: Cleaning mattress with Baking Soda
After spot cleaning, it’s time to deodorize your mattress. Baking soda is an excellent natural deodorizer that helps absorb moisture, eliminate odors, and break down acids.
Sprinkle a light, even layer of baking soda over the entire surface of the mattress. Don’t worry about using too much—you’ll vacuum it up later.
Let the baking soda sit for at least 30 minutes. For stronger odors or older mattresses, you can leave it on for several hours or even overnight.
The longer the baking soda sits, the more effective it will be at:
- Absorbing body oils
- Eliminating odors
- Drawing out moisture
- Breaking down acid residues
Once the baking soda has done its job, thoroughly vacuum the mattress again to remove all the powder.
Step 5: Air It Out
Proper drying is essential when you deep clean a mattress. If possible, move your mattress near an open window or into direct sunlight for a few hours. Sunlight is a natural disinfectant and helps kill remaining bacteria. The UV rays can also break down any remaining odor molecules.
If moving the mattress isn’t practical, increase airflow by:
- Opening windows in the room
- Setting up fans around the mattress
- Running a dehumidifier to pull moisture from the air
Make sure the mattress is completely dry before putting on fresh bedding. Any remaining moisture can lead to mold or mildew growth inside the mattress.
Step 6: Flip or Rotate the Mattress
While your mattress is still bare, take the opportunity to flip or rotate it. Keep in mind many newer mattresses aren’t designed to be flipped, though most can be rotated 180 degrees.
Rotate the mattress to:
- Promote even wear
- Extend the life of your mattress
- Improve your sleep
Check your mattress care tag or manufacturer’s recommendations before flipping. Some specialized mattresses have specific top and bottom layers and should only be rotated, not flipped.
“As a general rule, rotating your mattress every 3-6 months helps maintain its shape and support.”
Step 7: Add a Protective Mattress Cover

The final step to keep your freshly cleaned mattress in good condition is adding a protective layer. Consider using a zippered, allergen-proof mattress cover.
These covers create a barrier that blocks:
- Dust mites
- Mold spores
- Skin flakes
- Pet dander
- Liquids (if waterproof)
A good mattress protector can be easily removed and washed regularly. This simple addition can significantly extend the time between deep cleanings and protect your investment.

Tips for Ongoing Mattress Freshness
Learning how to deep clean a mattress is important, but preventing buildup in the first place is even better. Follow these simple practices to keep your mattress fresher between deep cleanings:
Daily Habits
Don’t make your bed immediately after waking up. Pull back the covers and let your mattress air out for about 30 minutes. This allows night sweat to evaporate instead of being trapped under the covers all day.
Weekly Maintenance
Wash your sheets and pillowcases weekly in hot water. This removes the oils, skin cells, and dust that would otherwise make their way into your mattress. Fresh bedding is the first line of defense against a dirty mattress.
Monthly Care
Vacuum your mattress monthly, even if you’re not doing a full deep clean. This quick step removes surface dust and allergens before they can settle deeper into the mattress. It takes just a few minutes but makes a big difference over time.
“We love our pets, but let’s be honest, they can get into some pretty nasty stuff. They also don’t give a second thought to diving onto our clean bedding. So, I have a tip for grabbing pet hairs that may have found their way into mattress fibers. Keep a roll of duct-tape handy. Cut a strip that’s long enough to circle around your palm—but reversed—sticky-side out. The idea is to make a cuff, or loop of tape. Now simply pat down your mattress problem area. Rotate the loop as the tape gets covered. You’ll be shocked at how effectively this grabs pet hairs.”
Pet Considerations
If possible, keep pets off the bed, especially if allergies are a concern. Pet dander and hair can quickly work their way into mattress fibers and are difficult to remove completely.
Climate Control
In humid climates, use a dehumidifier in your bedroom. Keeping the humidity below 50% helps prevent mold growth in your mattress and improves air quality.
Special Considerations for Seniors and Caregivers
Deep cleaning a mattress can be physically demanding. If you’re an older adult or caring for one, consider these adaptations:
Equipment Choices
Use lightweight vacuums with long attachments to reduce strain. Cordless stick vacuums can be easier to manage than heavier canister models.
Time Management
Break the process into shorter cleaning sessions over a day or two. There’s no need to complete all steps at once if it’s too physically demanding.
Professional Help
Consider professional mattress cleaning services for seasonal deep cleaning. Many companies offer specialized services designed specifically for mattresses.
Safety First
Only rotate or flip mattresses if it’s safe to do so. Many modern mattresses are quite heavy. When in doubt, ask for help or skip this step entirely.
The Benefits of a Clean Mattress
Taking the time to deep clean a mattress provides many benefits beyond smelling fresh. A clean mattress can:
- Reduce nighttime allergies and improve breathing
- Decrease asthma symptoms
- Provide a more hygienic sleep environment
- Remove dust mites that can cause skin irritation
- Extend the useful life of your mattress
- Improve overall sleep quality
“Mattress cleaning isn’t about perfection—it’s about creating a healthier place to rest your head.”
A clean mattress contributes significantly to better sleep quality and overall health. While deep cleaning might seem like a big project, breaking it down into these manageable steps makes it much easier. Even performing a partial cleaning is better than none at all.
Here’s a quick recap you can print or save:
