How to Clean a Memory Foam Mattress Topper

How to effortlessly clean and refresh your memory foam mattress topper?

“If you think that memory foam mattress toppers improve your sleep, then you must add overall maintenance to your own home upkeep list.” -

There is no room for compromise.You should clean yours at least once a year up to once every two or three months. To refresh it is doable and will help you keep dust mites, bacteria, many types of mold and odor away from your mattress topper, and away from your home.

Without further ado, here are the care tactics which will help you to keep your mattress topper neat and clean:

Start With Preparation!

“With memory foam mattresses and toppers, hand washing is advisory. Avoid machine cleaning as it can ruin the memory foam and you will end with pieces instead of a whole topper. As you most likely know, it’s a gentle material.” -

So, roll up your sleeves and get down to work:

  1. Remove your memory mattress topper from the bed and position in on the ground.
  2. Take a good look for any stains or unpleasant odors.
  3. Choose where you will clean it:
  • Bathroom: If you are tackling stains, you should better do it in the bathroom. Turn the fan on to keep the room ventilated
  • On the floors: Always place a tarp or pad underneath to preserve the floor finish. If possible, go outside.

      4. Gather your cleaning tools:

  • Vacuum cleaner with an attached soft brush head;
  • Mild fabric cleaner;
  • Water and a spray bottle;
  • Baking soda, hydrogen peroxide (for removing stains);
  • Vinegar (for pre-treating stains).

Proceed with Vacuuming

Cleaning a mattress topper starts with a good and thorough vacuuming. Grab your vacuum cleaner and use the soft brush head attachment.

  1. Clean while doing circular movements. Work your way across the bed topper and get as much of dust and dirt particles you can get. Don’t rush it regardless of the size of your bedding..
  2. For eggshell-style toppers: tackle the spaces between the peaks as dust and debris are likely hiding in there. You can slightly bend it over the tricky spots to ensure a better access to the vacuum cleaner.
  3. Let's assume your mattress topper is free from any stains and odors (find more on that a few rows below). You should proceed with spraying it with the detergent you will learn to prepare later on.
  4. Pick a gentle laundry detergent and mix one part of it with two parts of warm water. Pour the solution into the spray bottle and gently spray over the entire mattress. Avoid soaking the foam, have a tempo and move your hand while spraying.
  5. Make sure you don’t forget the bottom side of your topper. Using the solution, spray the surface and let it air dry completely

Alternatively, you can use pure white vinegar instead of a mild laundry detergent:

  • Pour white vinegar into a spray bottle without diluting it.
  • Spray a thin coat over the mattress topper and let it air dry. The vinegar acts as a natural disinfectant and will disinfect your piece.
  • Don’t forget to spray over the bottom side of your mattress topper.

The white vinegar will eliminate bacteria and keep bad odor away from your piece.

How to remove nasty stains from your topper?

Unfortunately, accidents do happen and mattress toppers are not immuned against such. If an accident occurs, calm down and act quickly.

How to remove wet spills or stains?

To clean a mattress topper from wet spills or stains, take a dull knife or spoon and gently remove any solids from the foam. Using white paper towels, blot as much of the moisture as you can.

When the surface is almost moisture free, dampen the stained area with clear water and sprinkle with laundry borax. Using a sponge or a clean cloth, work the borax into the affected area until it is fully absorbed.

Let the borax stay for 15 minutes. To get rid of the residue, grab the vacuum cleaner with a brush attachment and remove the mattress topper. Repeat until there is no residue left.

* Note:
Work your way from the outside edge of the spill toward the middle of it, this way you won’t spread the stain further.

How to remove blood stains?

Moisten a sponge or a cloth with hydrogen peroxide (preferably 2%). Blot the area from the edges toward the middle of the spot. As the stain is coming out, switch to a clean cloth to avoid spreading it on the topper’s surface.

Warning note: Using hydrogen peroxide may cause the foam to turn yellowish but will eliminate blood stains without harming the foam. Be cautious with it. You can find more on the subject here.

How to remove unpleasant odors from urine or vomit?

To fight these nasty smells, generously sprinkle the affected area with baking soda. Let it sit on the mattress topper for a day. Then grab your vacuum cleaner and vacuum the baking soda away.

Note: Struggling with cigarette smoke odor? Baking soda works great against cigarette smoke odors!

Using a cover for your topper is a smart move.

If your sleep gear consists a cover for your topper, you need to take care of it on a weekly/bi-weekly basis.

Can you wash memory foam mattress toppers?

Luckily, it can simply be tossed in the washing machine. You can clean your cover as frequently as you want to without worrying about unexpected damage.

In case you plan to buy a cover, go for a cotton one, it is extremely soft which will keep your skin happy. Also, using a cover will protect your memory foam mattress topper and keep it clean and neat in the long term.

How much does the mattress topper take to completely dry?

Whatever the stain was, whatever you did to remove it, always let the topper to air dry for at least 24 hours before bringing it back on the mattress. A smart move is to place the topper on its edge so the air can flow around all its sides.

Please note that drying time can vary and may go beyond 24 hours if the stain removal process was too intensive. Still, a fan may come in handy in such cases. ”You can place a fan near the mattress topper to speed up the drying process", suggests Dean Davis, specializing in mattress cleaning professional at "Failing to ensure a proper air flow around the topper will result in extended drying time.”, he adds.


The most valuable lesson here is that keeping your mattress topper in a mint condition requires regular maintenance and upkeep efforts. This means treating and removing stains as soon as they occur and not a minute later. This may sound time-consuming and overwhelming but will actually save you many scrubbing efforts in the long run.
