Cleaning Memory Foam
This process is designed to clean a Memory Foam Mattress, and can be easily adapted to use on mattress toppers and pillows.
What you will need:
- Hand vacuum or regular vacuum with soft brush attachment
- Woolite fabric cleaner
- Water
- Spray bottle
- Spray attachment for hose (if doing the task outdoors)
- Detachable shower head (if doing the task in the tub)
- Distilled white vinegar
- Hair dryer or electric fan
- Tarp
Cleaning Process:
- Vacuum the foam thoroughly with a hand vac or regular size vacuum using the soft brush attachment.
- Place mattress/topper/pillow in the bathtub or outside, near an outdoor water supply (if outdoors, make sure to place the mattress on a clean tarp or other clean platform to avoid getting it muddy or dirty).
- In the spray bottle, mix 1 part Woolite with 2 parts water and shake well.
- Standing the foam on end, spray entire piece(s), front and back, with Woolite solution. If cleaning the mattress, the job will be much easier with two people, one to hold the mattress, and one to spray.
- Allow Woolite solution to stay on for 30 minutes.
- Rinse with clean water, using detachable shower head if in the tub, or spray nozzle on hose, if outdoors.
- Gently squeeze out excess water by folding the foam and pressing down. DO NOT twist or wring the foam as this will cause damage.
- Empty Woolite solution and refill bottle with 1 part vinegar to 4 parts water.
- Spray down entire piece again with vinegar solution.
- Rinse again with shower head or spray nozzle and gently press out excess water as in step # 7.
- A hair dryer set on its lowest setting can be used to aid in drying; being careful not to hold the hair dryer too close or it will damage the foam.
- In the alternative, the mattress can air dry, using an electric fan to aid in drying.
- Make sure the foam is completely dry before replacing on bed.
Removing Stains from Memory Foam
The cleaning process above should remove most stains. For more stubborn stains, these methods may help:
- Dampen the stain with plain water and sprinkle with dry boric acid (20 Mule Team Borax, usually found in the laundry aisle of the grocery store), and blot the stain with a sponge or cloth in circular motion until it disappears. Blot dry and vacuum with hand vac or soft brush attachment to remove residue.
- Dampen a sponge or cloth with hydrogen peroxide and blot the stain in a circular motion (NOTE: hydrogen peroxide WILL DISCOLOR THE FOAM while eliminating the stain!
- Spray the stain with an enzymatic pet stain remover (such as Petzyme, available at most pet stores), and let sit for 15 minutes. Blot the area with a damp cloth and vacuum when dry.
- If these methods fail, you may consider contacting a mattress cleaning professional. Also, check with your mattress retailer as they may carry products specifically designed to assist with stain removal for your particular mattress.
NOTE: For stains that have soaked into the mattress padding, for health and sanitary reasons (i.e. bacteria can continue to grow inside the padding even after the surface stain is gone), it may be necessary to replace to mattress.
Removing Odors from Memory Foam
Odors from stains (especially urine or vomit) and from the air (such as cigarette smoke) can linger in foam. To remove odors, try any one (or more) of the following methods:
- Sprinkle the entire mattress/topper/pillow with baking soda and allow to sit overnight. Vacuum thoroughly with hand vac or soft brush attachment.
- Using a citrus-based cleaning product, spray the foam piece(s) lightly, and allow to dry. Vacuum thoroughly.
- Try a commercially available product such as Febreze (Proctor & Gamble) or FreshCare (Clorox), which are often effective at eliminating or reducing odors.
Additional Hints and Tips
- To extend the life of your mattress, it should be flipped and rotated (bottom to top) every six months.
- To prevent stains and keep your foam mattress/topper/pillows clean and fresh longer, change your sheets often and vacuum your Memory Foam regularly (using a hand vac or soft brush attachment).
- Before cleaning, always check the manufacturer’s tags on your Memory Foam pieces for additional cleaning tips, and make sure to follow all warnings and cautions on the tag to avoid damage.
- Always clean a stain as soon as possible for easier removal and to avoid having it soak into the mattress padding.

Just an addition to the entry on how to wash memory foam…
Keeping a team of footballers on hand to help handle the foam once it’s soaked with water is of utmost necessity. This stuff holds water like the sponge it is, and a large piece of sodden foam can weigh more than the person trying to wrestle it about. My neighbor, who witnessed the fun, is still laughing.
Best of luck. You’ll need it!

Hello,
Once you’ve cleaned you mattress, as best you can, you can sanitize it with a steam cleaner and then use a UV light to further kill any germs or bacteria that may remain in and on the mattress. Steam and UV light will kill any and most germ and bacteria.

I tried cleaning a memory foam and hurt my back trying to lift. I was washing out a cat urine stain, using the bathtub. I tried to pick up enough to turn and strained my back. I ended up hernating a disc as a result.
Don’t lift unless you have a partner to help (!!)especially when its wet

How do I store a memory foam topper? I have a good one that I am not using as I got a new bed and want to put it away until I can give it away to someone. Do I roll it up, fold it or what???

Last year I washed my memory foam pillow. I put it in a big utility sink and submerged it in a weak solution of laundry soap. It came out fresh as a daisy, but I had to wait almost a month before I could sleep on it! The task of getting all the soap and excess water out of it left me aching for two days. Then, on a rack, under a screen, under a blistering summer sun, it took nearly 3 weeks ’til it was fully dry in the center (luckily no mildewing, though).
Now I keep it in double pillow cases hoping I won’t have to do that again any time soon. Good luck!
