How to remove mold from a mattress

Updated April 11, 2017

A mouldy mattress is more common than most people realise. Mold spores travel through the air and when they are present in your environment for a long period of time, they can cause serious health issues. As a matter of fact, many people do not realise that there is mould in a mattress until it is thoroughly inspected. Basically, mould grows when there is dampness in the air or on the fabric of the mattress for an extended period of time. There are, however, methods of addressing a mouldy mattress you can try that focus on removing the dampness from the air and material and cleaning the bed.

  1. Use a vapour steam cleaner to clean the mattress thoroughly, taking your time to sanitise the mattress.

  2. If there is mould present in the mattress, there is a possibility that mould is in the same area as the mattress and it would be wise to clean the entire room at the same time.

  3. Use an air purifier or dehumidifier to clean and/or control the humidity in the room. Cleansing the air of mould spores, as well as controlling the amount of moisture that is in the air, will prevent mould growth.

  4. Remove the mattress from the bed frame.

  5. Take the mattress outside to a sunny location.

  6. Allow the mattress to sit in the sun for as long as possible. This will provide an environment in which the mattress can dry out and be refreshed.

  7. Once the mattress is dried out, vacuum it completely to remove any mould spores that may still be present in the mattress.

  8. Use a citrus cleaning product to clean the mattress. Do not saturate the mattress, as this will only add to the problem. However, using a minimal amount of citrus cleaner and a rag to blot up the excess will help draw out the mould from the mattress.

  9. Allow the cleaner to dry. You can use a fan to speed up the drying process.

  10. Sprinkle baking soda on the mattress. The baking soda will absorb dampness.

  11. Warning

    Some mattresses have been known to be sold with mould in them. Examine your mattress to be sure you do not have such a product if your mattress is relatively new. Not all mattresses can be cleaned or sanitised enough to strip the mattress of all mould. Therefore, if your mattress contains a large amount of mould, the healthiest alternative may be to discard it and purchase a new one.
