Paraformaldehyde Powder

• 1). Don your protective clothing.
  
  
• 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). Roll the foam as tightly as possible with the wadded up bed sheet.
  
  
• 4). Place the bed sheet and foam into a plastic bag. Close the bag, leaving a "neck" at the opening.
  
  
• 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). Allow the bag to sit, undisturbed for several days to allow the paraformaldehyde to kill the mold growth and absorb the odor.
  
  
• 7). Remove the bed sheet and suck the foam several times with the shop vac to remove the paraformaldehyde gas.
  
  
• 8). Remove the foam from the bag and un-wad.
  
  

Bleach

• 1). Combine 1/2 cup of household bleach with 1 gallon of water.
  
  
• 2). Pour the mixture into a spray bottle.
  
  
• 3). Spray the bleach-water mixture onto the foam.
  
  
• 4). Sit the foam in a sunny area to dry.
  
  

Laundry or Diswashing Detergent

• 1). Mix 1/4 cup of laundry or dishwashing detergent with 1 gallon of water.
  
  
• 2). Spray the molded areas of the foam with water to prevent mold spores from being released into the air.
  
  
• 3). Scrub the foam with a brush or sponge saturated with the detergent mixture.
  
  
• 4). Allow the foam to dry thoroughly.
