How to wash mattress topper?


Cleaning your mattress topper regularly is essential for maintaining its freshness and prolonging its lifespan. A clean mattress topper not only promotes better sleep hygiene but also helps to eliminate allergens and odors. In this article, we will guide you through the steps on how to wash your mattress topper effectively.

Gather the necessary materials

Before you begin the cleaning process, it is important to gather the necessary materials. Here are the items you will need:

Vacuum cleaner: A vacuum cleaner with an upholstery attachment will help remove loose debris and dust from the surface of the mattress topper.

Mild detergent: Choose a mild detergent that is suitable for delicate fabrics. Avoid using bleach or harsh chemicals as they can damage the mattress topper.

Stain remover (optional): If your mattress topper has any stains, you may need a stain remover specifically designed for the fabric type.

Bathtub or large basin: You will need a bathtub or a large basin that is big enough to accommodate the size of your mattress topper.


Before washing your mattress topper, check the care instructions provided by the manufacturer. Some mattress toppers may have specific cleaning instructions that you should follow. If there are no specific instructions, you can proceed with the general cleaning method outlined below.

Vacuum the mattress topper

Start by vacuuming the surface of the mattress topper using the upholstery attachment of your vacuum cleaner. This will help remove any loose debris, dust, or pet hair that may have accumulated on the surface. Pay extra attention to the seams and corners of the topper.

Spot clean any stains

If your mattress topper has any stains, treat them before washing. Follow the instructions on the stain remover product and apply it directly to the stained area. Gently blot the stain with a clean cloth or sponge until it lifts. Avoid rubbing the stain, as it may spread or damage the fabric.

Washing the mattress topper

Fill your bathtub or large basin with lukewarm water and add a small amount of mild detergent. Swirl the water to create a soapy solution. Place the mattress topper in the water and gently press it down to ensure it is fully submerged. Allow the topper to soak for about 15-20 minutes.

After soaking, gently agitate the mattress topper by hand to loosen any dirt or residue. Avoid wringing or twisting the topper, as it may damage the fibers. Once you are satisfied with the cleaning, drain the soapy water.

Rinsing and drying

Refill the bathtub or basin with clean water and rinse the mattress topper thoroughly. Continue rinsing until all the soap residue is removed. Gently press down on the topper to squeeze out excess water.

To dry the mattress topper, you have two options. The first option is to hang it outside on a clothesline or lay it flat on a clean, dry surface in a well-ventilated area. Make sure to flip the topper occasionally to ensure even drying. The second option is to use a dryer on a low heat setting. If using a dryer, add a couple of clean tennis balls to help fluff the topper while it dries.


Regularly washing your mattress topper is crucial for maintaining its cleanliness and extending its lifespan. By following the steps outlined in this article, you can ensure that your mattress topper remains fresh and free from allergens and odors.
