Basements are common locations for mold development due to high levels of moisture.

Mold spores develop in a room due to consistent exposure to moisture, humidity and warmth. As this fungus begins to grow, it develops into colonies and spreads from surface to surface. When left unattended a small area of mold on a damp floor can eventually spread to the wall, carpet, or nearby furniture. Prompt removal of mold, before it can spread, is the best tactic. But when mold spores have spread throughout the room, thorough clean-up with proper supplies is important to ensure the fungus is removed.


Step 1

Turn on a dehumidifier in the mold-infected room. The dehumidifier removes moisture from the air and surfaces and removes the damp conditions mold needs in order to survive.

Step 2

A sponge effectively helps clean mold from surfaces.

Fill a bucket with 1 cup household ammonia and 1 gallon hot water. Use the solution to wash down your walls and ceiling to remove mold spores and stains. Scrub the surfaces using a soft sponge, and then rinse off with plain water and dry with clean cloths.


Step 3

Dampen a clean cloth with undiluted white vinegar. Wipe down hard-surfaced furniture and flooring in the room to kill and remove mold. Change to a clean cloth as you remove the mold spores and stains so they're not transferred back to the surface.

Step 4

Stir 1 tbsp. dish washing detergent into 1 gallon hot water in a bucket. Dip a clean cloth in the soap suds and blot mold stains on carpet or upholstery to kill the fungus and remove the stains. Rinse the carpet or upholstered surface with a cloth dampened with water.


Step 5

Vacuuming is an instrumental part of removing mold from a room.

Allow carpeted and upholstered areas in the room to dry fully. Vacuum the surfaces to remove dead mold spores. Toss out your vacuum bag immediately so the spores can't be transferred elsewhere.


Open windows to keep fresh, dry air circulating in a room. Sprinkle carpeting and furniture with baking soda to remove musty mold smells. Allow the baking soda to sit overnight then vacuum it up.


Consult someone who specializes in mold remediation if you have mold as a result of a flood.
