How to wash foam mattress topper?


Cleaning and maintaining a foam mattress topper is essential to ensure its longevity and hygiene. Regular washing can help remove dirt, stains, and odors, keeping your mattress topper fresh and comfortable. In this article, we will provide you with a step-by-step guide on how to wash a foam mattress topper effectively.

Gather the Necessary Materials

Before you begin washing your foam mattress topper, gather the following materials:

Materials used:
– Mild detergent or laundry soap
– Bathtub or large basin
– Clean towels
– Water source (shower or faucet)
– Soft-bristle brush or sponge
– Vacuum cleaner (optional)


To prepare your foam mattress topper for washing, follow these steps:

Step 1: Remove the mattress topper from your bed and carry it to a spacious area where you can comfortably clean it.

Step 2: If your foam mattress topper has a removable cover, unzip it and remove it from the foam. Set the cover aside for separate washing.

Step 3: Place the foam mattress topper on a clean surface, such as a bathtub or large basin. Ensure the surface is free from any dirt or debris.

Washing the Foam Mattress Topper

Now that you have prepared the foam mattress topper, follow these steps to wash it:

Step 1: Fill the bathtub or large basin with lukewarm water. Avoid using hot water as it can damage the foam.

Step 2: Add a small amount of mild detergent or laundry soap to the water. Be cautious not to use too much detergent, as it can be difficult to rinse out completely.

Step 3: Gently submerge the foam mattress topper into the water, ensuring it is fully soaked. Allow it to sit for about 15-20 minutes to loosen any dirt or stains.

Step 4: Using a soft-bristle brush or sponge, gently scrub the surface of the foam mattress topper in a circular motion. Pay extra attention to any stained or soiled areas.

Step 5: Drain the soapy water from the bathtub or basin and refill it with clean lukewarm water. Rinse the foam mattress topper thoroughly to remove any remaining detergent.

Step 6: Once rinsed, gently squeeze out excess water from the foam mattress topper. Avoid wringing or twisting the foam, as it can damage its structure.

Drying the Foam Mattress Topper

After washing, it’s crucial to dry the foam mattress topper properly to prevent mold or mildew growth. Follow these steps for effective drying:

Step 1: Lay the foam mattress topper flat on a clean and dry surface, preferably outdoors or in a well-ventilated area. Avoid direct sunlight, as it can cause discoloration or damage.

Step 2: Allow the foam mattress topper to air dry naturally. This process may take several hours or even a day, depending on the thickness and density of the foam.

Step 3: To speed up the drying process, you can use a fan or a gentle breeze from an open window. However, avoid using heat sources like hairdryers, as they can damage the foam.


Regularly washing your foam mattress topper is essential to maintain its cleanliness and extend its lifespan. By following the steps outlined in this guide, you can effectively clean your foam mattress topper and keep it fresh and comfortable for a long time.
