How to Clean a Mattress at Home | The Full-Bed Refresh

Cleaning a mattress at home takes about an hour of work plus drying time, and the process is the same for most bed types.

You strip the bedding, vacuum every surface, spot-treat stains, deodorize with baking soda, and let it dry completely before making the bed again. Do this every six months or so, and a mattress can stay fresh for its full lifespan. A deep clean also cuts down on dust mites, dead skin, and the musty smell that builds up over time.

Here’s the step-by-step routine that gets the job done without damaging the mattress.

Strip The Bed And Wash Everything

Take off every layer: sheets, pillowcases, blankets, mattress pads, and protectors. Wash them separately according to their care labels. Most bedding handles a warm wash, and a hot wash (around 60°C) works if the label allows it. While those run, the mattress is bare and ready for attention.

This step matters more than it seems. A mattress protector catches most sweat and skin flakes, so washing the layers is half the cleaning. If you don’t use a protector, the mattress itself is doing all the work.

Vacuum The Whole Surface, Seams, And Sides

Attach the upholstery tool to your vacuum, or use a handheld model, and go over the entire mattress. Pay special attention to seams, crevices, edges, and the sides of the mattress — dust and debris settle there just as much as on the top. Use slow, overlapping passes so the suction actually pulls out what’s embedded.

One pass won’t get everything. If you have a pet that sleeps on the bed, or you’ve had the mattress for years, go over it twice. The goal here is to remove the dry debris before any liquid touches the fabric.

Spot-Treat Stains Without Spreading Them

For stains, blot — never rub. Rubbing pushes the stain deeper into the mattress fibers and makes it harder to remove. Apply a small amount of cleaner to a cloth or spray the mattress lightly, then blot gently with a clean damp cloth.

Effective homemade cleaners include mild dish detergent mixed with water, white vinegar and water, hydrogen peroxide with dish soap, or an enzyme cleaner for organic stains like blood or urine. For memory foam mattresses, use only cleaners marked safe for foam and avoid oversaturating the surface. If you’re unsure, steam cleaning works well too, but only if your mattress manufacturer’s care instructions allow it. Always check the care label before choosing a method.

Deodorize With Baking Soda, Then Dry Completely

Once stains are treated, sprinkle a generous layer of baking soda over the entire mattress surface. Let it sit for at least 15–30 minutes — longer is better, and a few hours gives it time to absorb odors. Then vacuum it up thoroughly, again using the upholstery attachment.

This is also a good time to compare cleaning solutions if you’re in the market for a dedicated product — a cleaner made specifically for mattresses can handle stubborn odors and stains more effectively than household staples.

After vacuuming, let the mattress dry completely before putting bedding back on. Open windows or point a fan at the bed to speed things up. The most common mistake people make is remaking the bed too soon — trapped moisture invites mildew and odors.

FAQs

How often should a mattress be cleaned?

Most experts recommend a full clean every six months. That means stripping the bedding, vacuuming, and deodorizing with baking soda. In between, washing sheets weekly and using a mattress protector cuts down on how much dirt reaches the mattress in the first place.

Can I use a steam cleaner on my mattress?

Steam cleaning works well on innerspring and hybrid mattresses, but only if the care label allows it. Memory foam is usually a poor candidate because heat and moisture can damage the foam structure. Check the manufacturer’s instructions first, and if steam is allowed, keep the surface dry afterward.

What’s the fastest way to dry a mattress after cleaning?

Airflow is everything. Open windows, run a ceiling fan, or point a box fan directly at the mattress. If the weather is humid, a dehumidifier helps. Most mattresses dry within a few hours with good airflow, but thick memory foam can take much longer. Never remake the bed until the surface feels completely dry.
