Mold is both unsightly and potentially hazardous to those who come in contact with it. Mold grows in damp, dark places and is a common occurrence after a flood. Mold can grow on just about any surface, including wood and particle board. Unfortunately, particle board is a porous material, and once it has been infested it is extremely difficult to get rid of the mold. There is a method that you can try to rid the particle board of mold. However, if after trying the mold removal method, there is still mold present you will need to remove the particle board and replace it.
Equip yourself with the correct safety items. When working with mold always wear an N-95 respirator, safety goggles without vent holes, rubber gloves, long-sleeve shirt and pants.
Remove as much of the mold off of the particle board as possible. Use a damp cloth or a soft bristle brush to scrape off the mold.
Mix 1 cup of household bleach with 1 gallon of warm water in a 5-gallon bucket.
Scrub the particle board with a sponge saturated in the bleach-water mixture. First, test the bleach-water mixture for discoloration on a small out of view area of the particle board.
Allow the particle board to dry completely. Point fans at the particle board to help the drying process.
Apply a stain blocking chemical to the particle board to help protect it against future mold growth.
