A clean mattress topper is essential for a good night’s sleep and overall well-being. If you’re looking for a natural and effective way to clean your mattress topper, look no further than your kitchen pantry. 

Baking soda, a versatile household ingredient, can work wonders in lifting stains, neutralizing odors, and rejuvenating your sleep surface. 

In this guide, we’ll walk you through the step-by-step process of using baking soda to clean your mattress topper and ensure a fresh and comfortable sleep environment.

Let’s begin.

Gathering Your Supplies

Before you begin, gather the necessary supplies. You’ll need baking soda, a vacuum cleaner with a brush attachment, a soft brush, and optional essential oils for a pleasant aroma.

Removing Surface Debris

Start by giving your mattress topper a good shake to loosen and remove any loose dirt, dust, or debris. Gently pat the surface to further dislodge any particles. Regular maintenance like this helps prevent the buildup of deeper stains and odors.

Sprinkling Baking Soda

Evenly sprinkle a generous amount of baking soda over the entire surface of your mattress topper. Baking soda’s natural properties make it an excellent choice for deodorizing and lifting stains. Don’t be afraid to be thorough with your application.

Working in the Baking Soda

Use a soft brush to gently work the baking soda into the fabric of the mattress topper. This helps the baking soda penetrate the fibers, allowing it to effectively lift dirt and absorb odors. The gentle scrubbing action also ensures even distribution.

Letting It Sit

Allow the baking soda to sit on the mattress topper for at least 15 minutes to an hour. During this time, the baking soda will absorb moisture and odors, leaving your topper feeling fresh and clean.

Vacuuming the Topper

Use a vacuum cleaner with a brush attachment to thoroughly remove the baking soda. Make sure to use a low-suction setting to avoid damaging the delicate fibers of the topper. This step will also help eliminate any remaining dirt or debris.

Sunlight and Fresh Air

On a sunny day, consider placing your mattress topper outdoors to benefit from sunlight and fresh air. Sunlight has natural antibacterial properties that can help disinfect the topper and eliminate bacteria. Fresh air further aids in removing any lingering odors.

Spot Cleaning Stains

For stubborn stains, you can create a paste using baking soda and water. Apply the paste to the stained area and gently scrub with a soft brush. Allow the paste to sit for a short time before vacuuming it up.

Dealing with Odors

Baking soda is a powerful odor absorber. If you prefer a scented topper, you can add a few drops of essential oil to the baking soda before sprinkling it on the topper. Lavender, tea tree, and eucalyptus oils are popular choices for their refreshing scents.

Caring for Different Types of Toppers

Keep in mind that different types of mattress toppers require specific care. Memory foam, latex, and down toppers each have their unique characteristics. Follow manufacturer guidelines for cleaning and maintenance to ensure the longevity of your investment.

Frequency of Cleaning

Regular cleaning is key to maintaining a hygienic sleep environment. Aim to clean your mattress topper every few months or as needed. This routine not only extends the life of your topper but also promotes healthier sleep.

Alternatives to Baking Soda

While baking soda is an excellent choice for cleaning, other natural alternatives like vinegar and hydrogen peroxide can also be effective. However, baking soda’s gentle nature makes it a preferable option, especially for delicate fabrics.

Extending the Lifespan of Your Topper

To further extend the lifespan of your mattress topper, consider using a protective cover. A cover acts as a barrier against spills, stains, and dust, keeping your topper cleaner for longer.


Cleaning your mattress topper doesn’t have to involve harsh chemicals or complicated processes. Baking soda offers a simple, natural, and effective solution for lifting stains, eliminating odors, and maintaining a fresh sleep environment. 

By following the steps outlined in this guide, you can ensure that your mattress topper remains clean, comfortable, and conducive to a restful night’s sleep.
