Knowing how to clean a mattress is an essential part of home maintenance that often gets overlooked. A clean mattress not only promotes better sleep but also helps eliminate allergens and extend the life of your bed.
We spend about a third of our lives sleeping, so it makes sense to keep that space fresh. This guide will walk you through everything you need to know, from routine upkeep to tackling tough stains and odors. You’ll learn simple methods that require common household items, so you can get started right away.
How To Clean A Mattress
This main cleaning process is a deep clean you should perform every six months. It’s perfect for a general refresh or before you put on fresh sheets. You’ll need a few supplies to get started.
Gather Your Cleaning Supplies
- Vacuum cleaner with an upholstery attachment
- Baking soda
- A mild dish soap or enzyme-based cleaner (for stains)
- Cold water in a spray bottle
- Clean white cloths or microfiber towels (avoid colored fabrics that may bleed)
- Hydrogen peroxide (3% solution, for tougher stains—test first on a small area)
Step-by-Step Deep Cleaning Process
1. Strip the Bed and Expose the Mattress
Remove all bedding, including sheets, mattress protectors, and pillowtops. Wash these in hot water to kill dust mites and remove oils. This gives you full access to the mattress surface.
2. Vacuum Thoroughly
Use the upholstery attachment to vacuum the entire mattress surface. Pay close attention to seams, tufts, and edges where dust and dead skin cells accumulate. This step removes dry debris and prepares the surface for deeper cleaning.
3. Spot Treat Any Stains
For any visible stains, use a gentle cleaning solution. Mix a small amount of dish soap with cold water. Dab (don’t rub) the stain with a cloth dipped in the solution. Blot with a dry cloth to lift the moisture and stain. For biological stains, an enzyme cleaner is more effective.
4. Deodorize with Baking Soda
Sprinkle a generous amount of baking soda over the entire mattress. Let it sit for at least several hours, or ideally overnight. Baking soda is a fantastic natural deodorizer that absorbs moisture and neutralizes odors.
5. Vacuum Again
Once the baking soda has sat, vacuum it all up. This will leave your mattress smelling fresher and feeling cleaner. Make sure you get all the powder out of the seams.
6. Let it Air Dry Completely
If you used any liquid during spot cleaning, it’s crucial to let the mattress dry fully before remaking the bed. You can use a fan or open a window to speed up the process. A damp mattress can lead to mold and mildew.
How to Handle Specific Stains
Different stains require slightly different approaches. Here’s a quick reference for common problems.
- Urine or Other Biological Stains: Blot up as much liquid as possible. Use an enzyme cleaner specifically designed for pet or human accidents, following the product instructions. These break down the proteins in the stain.
- Blood Stains: Always use cold water, as hot water sets the protein in blood. Apply a paste of baking soda and cold water, or dab with diluted hydrogen peroxide (test for colorfastness first).
- Coffee or Tea: Blot, then clean with a mixture of mild soap and cold water. A vinegar-water solution can also help.
- Mold or Mildew: Mix equal parts rubbing alcohol and cold water. Lightly spray and scrub the area, then dry thoroughly with a fan. Address the source of moisture to prevent it from returning.
Maintaining a Clean Mattress Between Deep Cleans
Regular habits can drastically reduce how often you need to deep clean. Here are three easy tips.
- Use a Mattress Protector: This is the single best thing you can do. A quality, waterproof protector acts as a shield against spills, sweat, and dust mites. Just wash the protector regularly.
- Air it Out Monthly: When you change your sheets, leave the mattress bare for a few hours. Open a window if you can. This allows moisture to evaporate and fresh air to circulate.
- Vacuum During Sheet Changes: Give the mattress a quick vacuum every time you put on fresh sheets. It takes two minutes and prevents buildup.
Why a Clean Mattress Matters for Your Health
A dirty mattress can impact your sleep and well-being. Over time, it accumulates dust mites, their droppings, dead skin cells, and body oils. This can exaserbate allergies, asthma, and skin conditions like eczema. Regular cleaning reduces these irritants, leading to cleaner air and a healthier sleep environment. It also prevents the growth of mold and bacteria from accumulated moisture.
When to Consider Professional Cleaning
While DIY cleaning is effective for maintenance, there are times to call a pro. If you’re dealing with a very old mattress that’s never been cleaned, extensive staining, or persistent odors you can’t remove, professionals have stronger extraction tools. They are also a good option if you have severe allergies or purchased a second-hand mattress and want it sanitized thoroughly.
FAQ Section
How often should you clean your mattress?
You should vacuum your mattress monthly when changing sheets. A full deep clean, like the one described above, should be done every six months. If you have allergies or pets, you might want to do it more frequently, like every three to four months.
Can you use vinegar to clean a mattress?
Yes, white vinegar is a great natural cleaner for odors and some stains. Mix equal parts vinegar and water in a spray bottle. Lightly mist the area (don’t soak it), then blot with a dry cloth. Always let the mattress dry completely. The vinegar smell will dissapate as it dries.
What’s the best way to get smells out of a mattress?
Baking soda is your best friend for odors. Sprinkle it liberally, let it sit for hours, and vacuum. For stronger smells, you can add a few drops of essential oil to the baking soda before sprinkling. Ensuring the mattress is completely dry is also key, as moisture causes musty smells.
Is steam cleaning safe for mattresses?
It can be, but you must be cautious. High heat can kill dust mites and bacteria, but too much moisture can lead to mold inside the mattress. If you use a handheld steamer, hold it several inches away and don’t saturate the fabric. Ensure the room is well-ventilated and the mattress dries completely within 24 hours. Many manufacturers advise against it, so check your warranty.
How do you clean a memory foam mattress?
Memory foam is sensitive to moisture, so you must avoid soaking it. Never use a steam cleaner. Follow the spot-cleaning and baking soda deodorizing steps carefully, using minimal liquid. Blot, don’t rub, and be extra patient during the drying phase. Always check the care label from the manufacturer first.
Final Tips for Success
Always check your mattress warranty for any specific cleaning instructions to avoid voiding it. Work in a well-ventilated room to help with drying and to avoid inhaling dust or baking soda. And finally, be patient—rushing the drying process is a common mistake that leads to bigger problems. With these steps, your mattress will provide a cleaner, more comfortable place to rest for years to come.
