Before you start cleaning, make sure to have a large open space where you can easily wash and dry your mattress topper. Moreover, you will need to reserve an entire day for cleaning your mattress topper, especially if there are any stubborn stains.

Quick or deep cleaning?

Depending on how dirty your mattress topper is, you can opt between two types of cleaning: quick or deep cleaning. Ideally, you should go for deep cleaning so that your mattress topper stays clean for longer. Even if you buy the best memory foam mattress toppers, they can get quite dirty with prolonged usage. We will discuss both methods so that you don’t have a hard time deciding which one to go for.

Fast cleaning method

Fast or quick cleaning allows you to clean your memory foam mattress topper if it hasn’t been used for too long, or it doesn’t appear really dirty or smell different. It is also useful if you want to remove a stain from a certain spot on your mattress topper. Bear in mind that if there are stains on both sides of the bed, you will need to spend twice the time in cleaning the topper. Here are a few simple steps that you can follow for fast cleaning.

Vacuum cleaning

How to Clean a Memory Foam Mattress Topper?The first step requires you to take off the mattress topper from your mattress and place it on a clean and dry surface. It would be better to put the topper on a plastic sheet. Next, attach the hose extension to the vacuum cleaner and start cleaning the surface. This will remove all of the dust and debris from the top.

Stain removal

How to Clean a Memory Foam Mattress Topper?After you finish vacuum cleaning, you can get to work on removing those stubborn stains and spots on your mattress topper. For this method, you can use various cleaning agents, but it is best to use a mixture of detergent and vinegar or baking soda as this helps remove stains. If you use the former, you can dilute the vinegar with water and apply it to the stains and spots. Next, wipe it with a cloth until it is fully removed.

Now you can dilute the detergent with a little more water, dip a dry cloth into the solution and apply it to the same areas as the vinegar solution. You can also spray this solution on the stains. Wait for at least 30 minutes to let the solution work its magic.

If you have baking soda, mix it in water with a 1:2 ratio and stir until completely dissolved. You can apply this solution to the stains with a cloth and wipe them until the stains start to fade away. Leave the mattress topper for at least an hour for complete cleaning.

Removing excess moisture

Once you rinse the surface of your memory foam mattress topper properly and you don’t see any soapy residue, you can take an absorbent towel and dab it on the spots to remove any excess moisture from the topper. Keep switching towels when one starts getting wet.


Now that the cleaning is over, you can simply leave the mattress topper to dry with a fan, or you can use a hairdryer for quicker drying. Keep the dryer at a significant distance from the mattress topper so that it doesn’t cause any damage.

Deep cleaning method

If your memory foam mattress topper has large and stubborn stains like coffee, quick cleaning won’t help you, and you will have to go for a full cleaning. This is because the liquid is deeply soaked by the memory foam and won’t disappear just by spot cleaning. Here is the entire process that you can follow to a clean memory foam mattress topper.

Initial steps

The first five steps of full cleaning are the same as quick cleaning, so you can just apply them as you see above.


After you are done with the initial steps, you have to wash your mattress topper with cold water. This will wash and rinse off all of the detergents. Keep washing and wiping off the surface of the topper until all of the detergents wash away completely.


For the next step, you have to roll the mattress topper inwards and gently apply pressure to expel water from it. To maintain your mattress’s softness and durability, don’t squeeze it too hard or tumble dry.


The next and last step of the full cleaning process requires you to place the mattress topper to dry, preferably somewhere where there is a decent airflow but no direct sunlight. Just like quick cleaning, you can use fans or hairdryers to dry up the mattress quickly.

What to avoid

Now that we discussed in detail what you need to do to clean your mattress topper efficiently and properly, it is also time to understand what you shouldn’t do while cleaning your mattress topper. Since memory foam is different from other types of foams and fabrics, you can’t clean it the same way as you do with others.

Firstly, you should ensure that your mattress topper is fully dry, and never place it back on the mattress even if it is slightly wet or a spot on it hasn’t dried fully. Even a little bit of moisture can cause the mattress topper to develop mold, which can be quite nasty and detrimental to your health.

As we mentioned above, another thing to take care of is to not dry your memory foam mattress topper under direct sunlight, especially during the time of day when the temperature is at its highest. You may be tempted to do this to dry up your topper quickly, but this will damage its structure. You may, however, place it under sunlight when the heat is a bit lower.

The same principle applies to blow-drying your mattress topper. Make sure to keep it at a low setting and a few meters apart so that the heat doesn’t damage the topper’s surface. Use cold water for washing, as hot water can also be damaging for your topper.

Don’t use low-quality detergent to clean the stains off your mattress topper, as it can cause discoloration of the surface of the memory foam. Also, don’t squeeze your mattress too hard, and prevent machine washing and tumble drying, as these can severely affect the softness of the memory foam.
