Cleaning Mattress Toppers: Step By Step Guide

Hailed for their numerous benefits, mattress toppers need regular maintenance not only to please you aesthetically, but also to keep you safe from allergies caused due to excessive dust accumulation. On top of that, a timely reaction for removing accidental spillages from your topper can prolong its life as it protects it from mould growth. 

To help you preserve your mattress topper for longer, we created a full guide on how to clean a mattress topper, so let’s get started.

How to Clean a Mattress Topper?

In order to clean mattress toppers properly, you need to follow the following steps: vacuum, wash its casing separately, treat spots, wash the filling, and thoroughly dry it before putting it on your mattress.

Vacuum Clean

In order to properly vacuum your mattress topper, you need to cautiously remove it from your mattress and place it on a flat surface, such as the floor. Laying it on the floor as well as using an upholstery attachment will enable you to clean every corner of your topper thoroughly. For best results, use either a handheld or water-based vacuum cleaner as they are the most convenient for this purpose. Make sure to use a soft brush attachment to prevent damaging the fabric cover that your topper uses. 

Once you are armed with the right equipment, gently clean those pesky dust particles using small circles. Flip your mattress topper and repeat the same process on its backside to avoid dust transfer.

Wash the Casing Around Your Mattress Topper

Most mattress toppers come with a removable cover that makes the cleaning process trouble-free. Simply remove the cover and, unless otherwise specified, put it in your washing machine using a gentle cycle with low temperature and a mild, liquid detergent.

Spot Clean Stains

The spot cleaning approach usually depends on the type and severity of the stain you are dealing with. 

Sweat, Urine, & Blood

Although not easy substances to clear once having set on the fabric, all protein-based stains of the bodily variety can be successfully removed with the right items and the right care.

  • Create a solution by fusing together baking soda, dish soap, and hydrogen peroxide within a spray bottle. Spray the stained area, gently rubbing it with a dry, clean, white cloth. 
  • Allow the mattress topper to fully air dry before returning it to your mattress as moisture accumulation can cause mold to form. Never wring it out to dry as you can tear or even destroy the material.

Red Wine

The thing about removing red wine stains is to act with caution as they can become permanent if treated improperly. This is why you should avoid applying heat directly to the stain and use a solvent that can allow dilution for you to wick it away with a gentle cloth. Do note, though, that scrubbing can aggravate your problem.

  • Mix three parts of hydrogen peroxide to one part dish soap and gently pour the solution on the affected area. 
  • Let it work its wonders for a while and pour once again to allow a complete disappearance of your stain. 
  • Repeat this process as much as necessary until the lifting effect of the solution starts working and there aren’t any visible stains. The best part is that you don’t have to risk damaging your mattress topper cover by scrubbing or rubbing.
  • As with the previous solution, make sure to completely dry your mattress topper before putting it on your bed.

Washing the Filling in Your Mattress Topper

As with the removable cover, the way in which you’ll wash the filling from your mattress depends on the materials. When it comes to memory foam mattress toppers, we don’t recommend soaking the filling in water. Use a removable and machine washable cover instead to protect the memory foam core from dust particles. 

On the other hand, polyester fillings can be machine washable, but before putting them into your washing machine, double-check your manufacturer’s instructions to avoid voiding your warranty.

Drying a Mattress Topper

Drying your mattress topper completely is perhaps the most overlooked yet highly important part of its maintenance. Keep it in a well-ventilated room until it fully dries to prevent any mildew or mold growth. 

If possible, place your topper somewhere where there is direct sunlight for thirty to forty minutes, but make sure to do so during the morning hours. Along with absorbing moisture, the heat has proven itself to impede bacteria growth as the UV rays penetrate the microorganisms’ cells and damage their ability to reproduce. Avoid direct sunlight at noon because excessive heat can damage the construction of your mattress topper.

Protect & Clean Your Mattress Topper Regularly

What if we told you that there is a way to protect your mattress topper from accidental spillages or sweats? By using a waterproof mattress protector on top of your topper, the process for cleaning will become a walk in the park. This is mostly because these are usually easy to clean as they are machine washable. To protect it from dust mite accumulation, vacuum at least once a week and shake your topper out regularly.

In Summary

Voila - now that you know how to properly clean your mattress topper you can certainly prolong its life while protecting yourself from any mold growth accidents or dust accumulation. 

Always remember that the most important thing is to never let any moisture linger as this can be harmful to your health as well as to your topper. To prevent any spillages, body oils, and sweat from penetrating its deep layers, use a mattress protector on top of your topper.


Can you wash a mattress topper?

Washing a mattress topper is as simple as it gets when it uses a removable mattress cover. If this is the case, just remove the cover and, according to the instructions of the manufacturer, either machine or hand wash it with lukewarm water and mild liquid laundry detergent. Washing the filing, on the other hand, depends on the material used in the production. For instance, the memory foam filling is not machine washable because you can waterlog or damage the spongelike structure of the foam. If it truly needs cleaning, then target any spots with a gentle cleaning solution. 

Can you wash a mattress topper in the washing machine?

Depends on the fabric the topper uses for the cover as well as the filling material. While most covers are machine washable, make sure to triple-check the instructions before deciding to put the cover in a washing machine. As for the inside, most polyester, microfibre, and down and feathers fillings are machine washable, but you will need a large size washing machine in order to wash them properly. Memory foam, on the other hand, is a gentler material that requires special care. This means that you should always spot clean stains on memory foam while washing its cover regularly to prevent dust from accumulating on the filling. 

How to get a stain out of a mattress topper?

There are numerous ways to get a stain out of a mattress topper, but the easiest is to mix equal parts of distilled white vinegar and water in a spray bottle. Gently spray the problem area with the solution and let it rest for a few minutes before you blot out the excess moisture with paper towels or a soft cloth. The next step requires you to sprinkle powdered baking soda over the entire mattress topper and let it rest for the night. Vacuum the mattress topper first thing in the morning using either a water-based or handheld vacuum cleaner to make the process effortless.

How to clean a memory foam mattress topper?

Cleaning a memory foam topper is plain sailing when the filling is wrapped in a machine washable casing. Just remove its cover and either machine or hand wash it (depending on the washing instructions), and, if necessary, spot clean the mattress by creating a baking soda solution. With this being said, pour a baking soda into a small plastic container and add twice as much water to it. Dip a clean cloth into the milky solution and gently rub on the stain so that it completely disappears. 

Can you wash a cotton mattress topper in the washing machine?

If your mattress topper uses a removable cotton cover, then it most likely (see the label) can be machine washed on a gentle cycle with cold water. However, washing the filling depends on the material inside.

How to clean wool mattress toppers?
