If you own a memory foam mattress topper, regular cleaning may be necessary to extend its life and eliminate stains and odours. A deep clean can help extend the longevity of your topper while increasing its performance. Here we are going to look into how to clean a memory foam mattress topper.

There are various ways and means to clean a memory foam mattress topper. Which one to use will depend on a few things including brand and personal preference. The following are some of the most common ways to clean a memory foam mattress topper.


Foam mattress toppers provide extra support and comfort to your bed, but they can become dirty from spills, body oils, sweat, and other particles that make cleaning difficult. To keep your memory foam mattress topper looking pristine, vacuum it regularly on both sides.

Vacuuming helps to remove dust, hair and other particles that can trigger allergies. Additionally, it prevents bacteria and dust mites from accumulating on the topper.

Once a week, use a vacuum cleaner to sweep away dirt and crumbs from the surface of your memory foam mattress topper. Doing this helps prevent microorganisms from forming and extends the life of your foam mattress topper.

For optimal vacuuming your memory foam mattress topper, use a handheld vacuum with soft brush attachment. However, if you don’t have one, any vacuum cleaner will do the trick; just be sure to do an even and thorough job on both sides!


Memory foam mattress toppers cannot be washed in the laundry like mattresses. The centrifugal force of a washing machine could tear apart its fine cells and degrade its cellular structure.

To avoid this, it’s essential to regularly and carefully clean your mattress topper. Furthermore, make sure it dries completely before placing it back on your bed.

A damp topper can foster mould and mildew growth, resulting in unpleasant odours and discolouring the mattress cover. Furthermore, it damages memory foam’s cellular structure and cell walls.

Preventing these issues with your mattress topper is the best way to go, by regularly cleaning it and spot-treating any stains that appear.

To begin removing stains, apply a vinegar solution and gently rub it onto the stained area. Next, dab up any excess liquid with a clean towel. Repeat this process until all traces of stain have been eliminated.

Baking Soda

Baking soda, also known as sodium bicarbonate, is an ingredient commonly used in baking that can help eliminate smells and moisture trapped inside memory foam. Additionally, it’s great for getting rid of stains from a mattress topper.

Memory foam mattresses can become stained and odorous over time, particularly when exposed to sweat or urine. Regular cleaning is the best way to keep your mattress looking like new and prevent odors, stains, and mildew from shortening its lifespan.

For a fast and effortless clean, sprinkle your topper with baking soda, let sit for 8 hours, then vacuum. This will eliminate lingering odours and help prevent them from forming again.

You can also clean a memory foam mattress topper with liquid laundry detergent and water, or use an enzyme cleaner. For tough stains, try white vinegar or hydrogen peroxide, However, be aware that these products may bleach the foam so use them sparingly.


When it comes to cleaning a mattress topper, vinegar is an effective and natural alternative to laundry detergent. It has less acidic properties than some common stains (like coffee or wine), so you can safely use it to clean a memory foam mattress topper without damaging either your mattress topper or sheets.

For stains, create a solution with equal parts white vinegar and water and apply it to the affected area with a soft cloth. Repeat this process until all traces of staining have been eliminated.

Vinegar is a liquid produced through two fermentation processes. The first is yeast feeding on sugar or starch from plant foods like fruits, vegetables, and whole grains. Then it undergoes another fermentation with acetic acid bacteria to form vinegar.

Although vinegar is one of the most naturally antibacterial household ingredients, it should never be used to wash a memory foam mattress topper in your home washing machine as this may cause it to tear or break down. It’s better to spot clean and air dry your memory foam mattress topper thoroughly in order to prevent mould or mildew growth.
