How to Kill Mold in Foam
Foam is a porous material and can be difficult to remove mould from. (pink foam image by laurent dambies from Fotolia.com)

Mold can grow on just about any surface including porous materials such as fabric and foam. When mould grows on porous materials, it is common to discard the item because of the difficulty in removing mould for them. However, it is not impossible to salvage these items and restore them to like-new condition.

Before beginning the mould removal process, equip yourself with the correct safety clothing. An N-97 respirator, rubber gloves, safety goggles without vent holes, long sleeve shirt and trousers should be worn at all times during the mould-removal process.

Instructions

    Paraformaldehyde Powder

  1. 1

    Don your protective clothing.

  2. 2

    Pour paraformaldehyde powder into an old bed sheet and wrap the bed sheet into a wad so that the powder is enclosed in the middle.

  3. 3

    Roll the foam as tightly as possible with the wadded up bed sheet.

  4. 4

    Place the bed sheet and foam into a plastic bag. Close the bag, leaving a "neck" at the opening.

  5. 5

    Insert a shop vac hose into the neck of the bag and suck to condense the foam into a little knot. Remove the hose and seal the neck closed.

  6. 6

    Allow the bag to sit, undisturbed for several days to allow the paraformaldehyde to kill the mould growth and absorb the odour.

  7. 7

    Remove the bed sheet and suck the foam several times with the shop vac to remove the paraformaldehyde gas.

  8. 8

    Remove the foam from the bag and un-wad.

    Bleach

  1. 1

    Combine 1/2 cup of household bleach with 1 gallon of water.

  2. 2

    Pour the mixture into a spray bottle.

  3. 3

    Spray the bleach-water mixture onto the foam.

  4. 4

    Sit the foam in a sunny area to dry.

    Laundry or Diswashing Detergent

  1. 1

    Mix 1/4 cup of laundry or dishwashing detergent with 1 gallon of water.

  2. 2

    Spray the moulded areas of the foam with water to prevent mould spores from being released into the air.

  3. 3

    Scrub the foam with a brush or sponge saturated with the detergent mixture.

  4. 4

    Allow the foam to dry thoroughly.
