When To Clean A Memory Foam Mattress?

There are two instances when you want to clean your memory foam mattress topper. First, you want to clean it for regular maintenance. In this case, you don’t need to completely wash it down.

Secondly, you want to clean it after you spill something on it or after your child wets it while sleeping. In this case, you might need to wash it down thoroughly.

Regular Maintenance

What you’ll need:

  • Vacuum cleaner
  • Stain remover
  • Mild laundry detergent
  • Cotton cloth
  • Spray bottle

Vacuum The Memory Foam

Vacuum The Memory Foam

Take the topper off the mattress and bring it to a dry, clean and flat surface. Then you can vacuum the whole topper to remove dust, dirt, dead skin cells and debris. Flip it as you see necessary, to be thorough. Make sure you go through every little corner, especially if the topper has crevices.

Spot Cleaning

Spot Cleaning

After vacuuming the topper, identify any spots that you need to remove. You will need a safe cleaning solution that can remove spots or stains. You can buy this in the store, or you can make your own at home, using vinegar and water. A baking soda paste may also help with stains.

Spray the cleaning solution on the spot, or dip a cotton cloth in the solution then dab on the spot. Wipe the spot until it’s clean. You will need to get rid of stains first, before cleaning the whole topper.

Apply Gentle Detergent On The Whole Surface

After spot cleaning, you can proceed to clean the whole topper. Dilute mild detergent with water. To apply it, you can either use a spray bottle to spray it on, or you can use a piece of cloth. Do not, I repeat, do not spill the solution on the mattress topper. You don’t want the detergent to go all the way into the inner parts of the foam. Keep it on the surface and let the detergent sit for about a few minutes to an hour.

Rinsing The Topper

You want to take out as much of the detergent out of the foam as possible. To do this, you will need clean water and a clean cloth. You can spray water on the foam and press on it with a cloth to remove the detergent. You can continue spraying water and dabbing it with an absorbent cloth until the water isn’t soapy anymore.

Drying The Topper

Use an absorbent piece of cloth or towel to blot out any excess water from the foam. You may want to remove as much moisture out of the foam before you air dry it so that it will dry faster.

Never put it directly under the heat of the sun because it can damage the foam. Take the memory foam mattress topper to a shaded and airy area. You can also use a fan to facilitate the drying process.

Washing The Whole Mattress Topper

Washing the whole mattress topper might be necessary if you accidentally spilled liquid on it. Bedwetting might also be a reason to completely wash it whole. The first steps include the same steps as a regular cleaning: vacuum cleaning, spot cleaning, and applying the detergent. Then, follow the steps below:

Wash With Water

Wash With Water

Instead of just spraying on the surface of the foam, you can wash it thoroughly. Use cold water because hot or warm water could damage the foam. You can run it with a hose as long as it is still on a flat surface.

Drain The Water

To drain the water, you can gently roll the topper like a mat. Don’t squeeze, as it could tear the foam. You can also press the water out with the use of a towel or an absorbent cloth.

Drying The Foam

After draining as much water as you can, bring the foam under shade where the breeze can catch it. You can also use a fan to facilitate a faster drying process. Remember, you don’t want to use it until it is completely dry. Damp foam or moisture is more susceptible for microorganisms to grow. It could develop mildew and a stench that could cause discomfort or problems to your health.

Other Care Tips For Memory Foam Mattress Toppers

  • Keep the foam away from heat. Do not use hot water on it and never dry it under direct sunlight.
  • Do not wash your memory foam topper in a washing machine. The motions could damage the foam and ruin its consistency.
  • For foul odors, try sprinkling baking soda on the foam. Let it sit for a few minutes before vacuuming it out.
  • Avoid eating or drinking on memory foam mattresses or toppers. This lowers the risk of accidental spills and soiling.



Keeping your topper and mattress clean is necessary for better sleep. Different types have different care instructions. That said, always make sure you refer to the care label for any specific instructions before you proceed with cleaning or washing.

Generally, Memory foam is easy to clean. The material is also not as prone to dust as other types of material. However, like every other thing, regular cleaning is still important to maintain its quality and maximize its lifespan.
