What Kills Mold on a Mattress?

To effectively remove mold from a mattress, it is important to know what kills mold and prevents it from coming back. This includes high-heat processes such as steam cleaning or dry cleaning, as well as natural solutions like baking soda, vinegar, tea tree oil, and hydrogen peroxide.

Additionally, products containing bleach can also be used to kill mold on the mattress surface but should not be used directly on fabrics due to potential staining. However, some of these solutions may not be suitable for all mattresses, so it’s important to check the manufacturer’s instructions before using any products.

Steam Cleaning or Dry Cleaning

When it comes to steam cleaning, a deep clean is often recommended as this will kill the mold spores and remove dirt and debris, which can help prevent the growth of further mold. Dry cleaning can also be used but should only be done by an experienced professional who is familiar with how to safely use chemicals on fabric items such as mattresses.

Using natural solutions like baking soda, vinegar, tea tree oil, or hydrogen peroxide can also help to kill mold on mattresses and are generally considered safe for most fabrics. To use any of these solutions, simply mix them with water and apply the solution directly to the affected area using a spray bottle. Allow the solution to sit for several hours before vacuuming off any remaining residue.

10 Methods How to Remove Mold from Mattress

1. Air It Out

The first step in removing mold from your mattress is to air it out. If the moldy area is small, you can simply open a window and let fresh air circulate. If the moldy area is large, you can place the mattress outside for a few hours. Doing this will reduce the amount of moisture in your mattress and help prevent mold from spreading.

Although, be sure to place the mattress in a dry, shaded area. When the mattress is dry, bring it back inside and proceed to step two. Make sure the area is well-ventilated to reduce the amount of moisture in the air.

2. Vacuum

Once you have aired out the mattress, vacuum it with a HEPA-filter vacuum cleaner. This will remove any mold spores that are on the surface of the mattress. Make sure to move the vacuum in all directions and to pay attention to seams, folds, and crevices.

Vacuuming is a good way to prevent future mold growth, as it can help keep the mattress free of dust and other particles that mold can feed off of. While you’re at it, take the time to vacuum your bed frame, headboard, and other furniture nearby. This will help keep mold from spreading in your bedroom.

3. Clean with Soap and Water

If the moldy area is small, you can clean it with soap and water. Use a mild detergent and scrub the area with a soft brush. Rinse the area thoroughly and allow it to dry completely. It is important to ensure the area is dry before moving on to the next step. If the area is still damp, the mold will continue to spread.

Although soap and water can be effective in removing small areas of mold, it may not completely remove all the spores. This method is best for addressing surface-level mold. Try to get to the root of the problem, such as a leaky pipe, and stop it from happening again.

4. Use Vinegar or Lemon Juice

If soap and water don’t seem to be doing the trick, you can try cleaning the moldy area with vinegar or lemon juice. Simply apply either of these solutions to the affected area and scrub with a brush. Rinse thoroughly and allow to dry completely. For an even deeper clean, use a steam cleaner.

Cleaning the Moldy Area With Vinegar

This will help to remove any mold particles that the vinegar or lemon juice may have missed. If you try this method, be sure to let the mattress air dry completely before reusing it. Mold and mildew thrive in damp environments, so it’s important to make sure your mattress is dry before sleeping on it. Remember that bleach should not be used as a cleaning solution for mattresses.

5. Use Baking Soda or Borax

Baking soda and borax are both effective at killing mold spores. To use either of these ingredients, simply make a paste by mixing them with water and apply it to the affected area. Scrub with a brush and rinse thoroughly before allowing it to dry completely. Do note that both baking soda and borax are not safe for use on colored fabrics, so take extra care when using them.

6. Use Hydrogen Peroxide or Bleach

Hydrogen peroxide and bleach are both effective at killing mold spores, but they should only be used as a last resort as they can damage some types of fabrics. To use either of these solutions, simply apply them to the affected area and scrub with a brush. Rinse thoroughly before allowing it to dry completely.

7. Dry Wet Areas Immediately

Mold thrives in damp environments, so it’s important to keep your mattress dry at all times. If your mattress gets wet, dry the affected area immediately with a towel or hairdryer on the lowest setting.

For deeper moisture, you may need to use a wet/dry vacuum. Keep the affected area out of direct sunlight, and do not cover it while drying. Once the area is completely dry, you can proceed with the next step. If possible, use a dehumidifier to speed up the drying process.

8. Use a Dehumidifier

If your home is particularly humid, you may want to invest in a dehumidifier to help keep your mattress dry and mold-free. Place the dehumidifier in the room where your mattress is located and set it to run continuously. This will help keep the humidity levels in check and should prevent future mold growth.

To ensure your mattress stays dry, open windows or use a fan to help move air around the room. This will help keep your mattress dry and prevent mold from forming. Additionally, you may also want to invest in a mattress protector to further protect your mattress from mold and other contaminants.

9. Cover Your Mattress with an Allergy Cover

An allergy cover can help to protect your mattress from mold spores as well as dust mites, pet dander, and other allergens. When choosing an allergy cover, look for one made of a tight-weave material that is breathable and can withstand washing in hot water.

Make sure the cover is specifically designed to fit your mattress size and follows the contours of its shape. After washing, air dry the cover completely or tumble dry on the lowest heat setting. To further prevent mold growth, make sure to air out your bedroom and vacuum regularly.

10. Use a Professional Cleaning Service

If you’re still having trouble getting rid of the mold, consider using a professional cleaning service. They will have the knowledge, tools, and experience to effectively remove the mold from your mattress. Professional cleaning services may also be able to prevent future outbreaks by providing appropriate advice on how to avoid future mold build-up, such as using a mattress protector.

This is a great option if you’re unable to completely remove the mold yourself. A professional cleaning service will be able to not only eradicate the mold, but they’ll also know how to safely and effectively get rid of it while protecting your mattress from further damage.


With all these steps in mind, you can now confidently tackle mold removal from any mattress. It is important to be aware of the dangers associated with mold and to take action and remove it quickly. Regularly inspecting your mattress for signs of mold growth, vacuuming and providing proper ventilation are key tips to help master prevention techniques for a healthier sleep space.
