A hardwood floor can be an ideal place for mold to grow if it has been exposed to water or high humidity. Removing mold is important to keep it from damaging the floor surface. Many types of mold can also create a health hazard. Get rid of mold by cleaning and disinfecting the floor, and adding a protective coat to the surface. Keep mold from coming back by removing the source of dampness.

Determine why mold has formed. Check for possible leaks, such as water coming through a window sill. Check for mold on any items in the room. Remove items that can collect mold, including newspapers and boxes. Block off the room from the rest of the house. Ventilate the room to decrease humidity. Blow air into the room with a box fan if it's hot and dry outside.
Use a vacuum that has a high-energy efficiency particulate air (HEPA) filter. A HEPA filter traps nearly all airborne spores that are produced by mold. Take vacuum outside. Discard old vacuum bag and replace it with new one.
Prepare a solution of 1 gallon of water and 1 cup of laundry detergent. Apply the solution to the floor with a mop or sponge, depending on the extent of the mold growth on the floor. Let floor dry completely.
Scrape off any visible mold with a scraper or plastic spatula. Scrape in the direction of the grain of the wood. Place any mold that came up in a garbage bag. Take garbage bag outside.
Mix a solution of 1 gallon of water with 1/4 cup of chlorine bleach and 1/2 cup of laundry detergent. Test the solution on a small part of the floor in a corner. If the hardwood floor changes color, prepare another solution without any bleach. The new solution consists of 1/2 cup of laundry detergent for each gallon of water.
Apply the solution to the floor with a mop or sponge. Wait 15 minutes to allow solution to seep into the mold.
Scrub the floor with a mop or sponge. Scrub with force to remove roots of the mold.
Dry the floor with a rag. Aim a box fan at the floor surface to help in the drying process. Blow air into the room with a box fan if it's dry and hot outside.
Sand the floor with 200-grit sandpaper. Sand in the direction of the grain. Sand until the hardwood floor is smooth.
Add a protective coat to the floor with a wood finisher. Use a brush to apply the wood finisher evenly.
