Is Wood Mold Dangerous
All mold has the potential to be dangerous. In the case of wood mold, not only can it cause health issues for the occupants of the building but it can also reduce the structural integrity of the wood it is growing on. Wood mold can be particularly dangerous since it is so difficult to see and may go undetected for very long periods of time.
Put On Protective Clothing
Prior to interacting with the mold, put on protective clothing, including a long-sleeved shirt and long pants. Wear old clothes because any bleach splatters will cause permanent stains. Also, wear a protective air mask, rubber gloves, and safety goggles. If possible take the mold-infested wood outside when cleaning to prevent spreading spores indoors. If you must remain indoors, close doors or use plastic sheeting to shield other areas.

The Difference Between Mildew And Mold
The most common type of mold found in homes is mildew. Mildew is a surface mold that grows in warm, damp places like basements, laundry rooms, and shady porches. Mildew begins as a gray or white powdery colony and eventually turns black or brown. To test whether the wood is covered with mildew or just dirt, dab the stain with a cotton swab dipped in household chlorine bleach. If the stain lightens or disappears after two or three minutes, it’s mildew. If not, it’s probably just dirt.
Mildew can discolor and slowly harm wood surfaces. But there are much more dangerous molds that can damage the structure of your home. If a fuzzy or slimy black or green mold is visible and the drywall or wood underneath is soft or crumbles, there is irreversible rot. The damaged surfaces must be removed immediately.
How To Clean Mold Off Wood With Soap And Water
Painted or stained wood is easier to clean, as the mold is not able to penetrate the stain or paint. As the mold spores havent penetrated through to the wood, you can use a mild cleanser to remove the surface mold with a high rate of success.
To clean mildew or mold, mix a squirt or two of dishwashing detergent and some warm water. Use a soft-bristled brush, dip it in the soapy solution, and gently scrub the moldy surface. Rinse with clean water.

How To Clean Mold From A Wood Floor
This is how I cleaned up and removed mildew that grew on a wood floor.I left a mattress directly on a hardwood floor, and some mold grew underneath. There is no insulation in the crawlspace beneath the floor, so the temperature differential between warm bodies sleeping on the mattress and cold air under the floor resulted in condensation between the mattress and the floor, which is a perfect place for mold to grow. Mildew can also grow under potted plants and carpet, against uninsulated walls, in damp basements, if you have a water leak, or even under wet laundry left sitting too long.
Protecting Yourself While Cleaning Moldy Surfaces
When cleaning mold from any surface, wear protective gear to keep yourself safe. Wear a respirator or air mask of some sort during mold removal to prevent mold spores from entering your lungs. Safety goggles and rubber gloves need to be worn at all times when cleaning up the mold to protect you from certain cleaning products, as well as mold spores.
If using bleach, wear protective outer clothing or old clothes as the bleach may cause stains. To remove mold from a large area like one that has a strong, musty smell, or one with extensive water damage, you not only want to wear protective gear, but you also want to take a few extra precautions.
These extra precautions prevent the mold from spreading throughout the rest of the house and will protect you from breathing in the spores and fumes from cleaning products you are using. Use an old box fan to ventilate the area you will be throwing it away when done as the spores are impossible to clean off the fan.
Moisten moldy areas while working, turn off furnaces and air conditioners while working, cover ducts and vents, and always leave your wet/dry vacuum outside double-bag and tape all moldy materials before throwing them in the trash.

One of the hardest issues to find and treat is when wood flooring mold problems are on the underside of the hardwood.

Hardwoods normally have moisture content levels of 10% or less. Once moisture content levels reach 18% or higher, there is a strong chance for mold to grow.
The only way to find a wood flooring mold problem that is under the hardwood is to physically look for it. At this point it is recommended that you contact a wood flooring installer or a mold remediation specialist. They will have the experience necessary to begin removing flooring planks without damaging them.
