How to get rid of mold on a mattress?


Mold growth on a mattress can be a common problem, especially in humid environments. Not only does it create an unpleasant smell, but it can also pose health risks. In this article, we will explore effective methods to get rid of mold on a mattress and prevent its recurrence.

Identifying the Mold

Before tackling the mold issue, it is crucial to identify the type of mold present on the mattress. Different molds may require specific treatment methods. If you are uncertain about the type of mold, it is advisable to consult a professional mold inspector.

Materials Needed

Materials used: To effectively remove mold from a mattress, you will need the following materials:
– Protective gloves
– Face mask
– Vacuum cleaner with a HEPA filter
– Baking soda
– Hydrogen peroxide
– Distilled white vinegar
– Spray bottle
– Clean cloth or sponge
– Plastic sheet or mattress cover

Step-by-Step Guide to Remove Mold

Step 1: Safety precautions
– Put on protective gloves and a face mask to avoid direct contact with mold spores and prevent inhalation.

Step 2: Isolate the affected area
– Move the mattress to a well-ventilated area with enough space to work around it.
– Place a plastic sheet or mattress cover underneath to protect the floor or other surfaces from mold spores.

Step 3: Vacuuming
– Use a vacuum cleaner with a HEPA filter to carefully vacuum the entire surface of the mattress, including the sides and crevices.
– Dispose of the vacuum bag or empty the canister immediately after vacuuming to prevent mold spores from spreading.

Step 4: Baking soda application
– Sprinkle baking soda liberally over the entire mattress surface.
– Gently rub the baking soda into the fabric using a clean cloth or sponge.
– Allow the baking soda to sit on the mattress for several hours or overnight. Baking soda helps absorb moisture and eliminate odors.

Step 5: Removing mold stains
– Create a solution by mixing equal parts hydrogen peroxide and distilled white vinegar in a spray bottle.
– Spray the solution onto the mold stains, ensuring thorough coverage.
– Let the solution sit for 10-15 minutes to penetrate the mold.
– Gently blot the stained areas with a clean cloth or sponge, working from the outside of the stain towards the center.
– Repeat this process until the mold stains are no longer visible.

Step 6: Drying the mattress
– After removing the mold stains, allow the mattress to air dry completely in a well-ventilated area.
– Ensure the mattress is completely dry before using it again to prevent mold recurrence.

Preventing Mold Growth

Maintaining a mold-free mattress:
– Regularly clean and vacuum the mattress to remove dust, dead skin cells, and moisture.
– Use a mattress protector or cover to create a barrier between the mattress and potential moisture sources.
– Keep the bedroom well-ventilated by opening windows or using a dehumidifier to control humidity levels.
– Avoid placing the mattress directly on the floor, as this can increase the chances of mold growth.


Removing mold from a mattress requires careful cleaning and thorough drying. By following the step-by-step guide and taking preventive measures, you can effectively get rid of mold and maintain a mold-free mattress. Remember to prioritize safety by wearing protective gear during the cleaning process.
