Mold on your mattress can put your health at risk. Mold spores travel in the air, and can cause you to become ill. Mold irritates the lungs of people with allergies and asthma. The substance thrives in dark, damp and humid locations. The mould will continue to spread if you do not treat it immediately. Once you notice mould on your mattress, you need to eliminate the health risk promptly to restore your mattress to its original condition.

Move your mattress outdoors on a sunny and dry day. Wear a protective mask and gloves before you remove the mould. Place the mattress on sawhorses or another object to keep it from sitting on the ground.

Vacuum the mould off the mattress with a shop vacuum.

Spray the mattress with an equal mixture of rubbing alcohol and warm water. This will remove the musty odour from the mattress. Test this mixture on a small inconspicuous area to ensure that it will not discolour the fabric.

Sprinkle baking soda over the mattress to absorb the moisture.

Place the mattress in direct sunlight. Bring the mattress indoors at night to prevent dew from ruining the mattress, and set it back outdoors to allow the sun to bleach the mould from the mattress.

Vacuum the mattress again before you place it indoors on your bed frame. This will remove any dirt and debris that you may not want to bring into your home.


Throw your mattress out if more than 50 per cent of it appears to be covered in mould to protect your health.
