Black mold, also known as Stachybotrys chartarum and Stachybotrys atra, manifests itself as a greenish-black substance that thrives in moist, poorly ventilated areas. Inhalation of black mold spores can cause or aggravate respiratory conditions like sinusitis, allergies and asthma. When black mold forms on porous materials such as carpet, aggressive measures must be taken to kill it. Be aware that not all outbreaks of black mold can be effectively contained. If the mold is too pervasive, you will need to replace your carpet.
Things You'll Need
- Plastic sheeting
- Duct tape
- Work gloves
- Dust mask
- Laundry soap
- Stiff brush
- Replacement carpet pad
- Professional carpet-cleaning equipment
To prevent the spread of mold while you clean, open all windows and turn off the heat and air-conditioning. Cover air vents in the affected room with plastic sheeting sealed with duct tape. Remove all uninfected furniture and belongings, and close all doors leading into the room with the infected carpet.
Raise the moldy carpet, if possible. If there’s a moldy or mildewing carpet pad beneath it, remove it, stuff it in a large plastic garbage bag, tie the top, and get it outside as swiftly as possible. To prevent spreading mold spores to other rooms, do not move the carpet from the room.
Scrub the floor beneath the carpet with laundry soap and warm water, using a stiff brush.
Mop the floor with a mixture of 1/4 cup bleach and 1 gallon of water, then let dry.
Vacuum and shampoo the moldy carpet with rug shampoo using professional carpet-cleaning equipment. The equipment can be rented from large home-improvement stores and some grocery stores.
Give the carpet time to dry completely, lay down a new carpet pad, and put the carpet back in place.
