3 Types of Mold on Wood (Black, White, & Green)
Green mold is typically some type of fungus. There are thousands of types of green mold, including Aspergillus, so it’s not always easy to identify by a non-expert upon sight. If the mold is olive-green, this is typically Cladosporium.
Black mold can also be Cladosporium or Aspergillus. They may also be Alternaria, which is common outdoors and in dusty indoor areas. If the mold is a greenish-black color, it may likely be Stachybotrys genus. This is the infamous “black mold” that is known to cause serious health problems.
White molds may belong to the Penicillium genus. While this is the mold from which penicillin is created, many people have allergies to this type of mold.
How to Kill Mold
Killing mold successfully usually requires several steps. First, its best to identify the mold, then gather the necessary supplies and protective gear. The best way to tackle a mold problem is as follows:
- Clean the infected area with soap and water.
- Use a mold killer (it should be a disinfectant that is capable of killing mold).
- Use a stain remover once the mold has been killed.
Active Ingredients
Keep in mind that bleach will not kill mold, it will only make it turn white or appear to disappear, but it will soon return. Bleach is more a mold stain remover than anything else. Most mold stain removers contain active ingredients such as hydrogen peroxide and sodium hypochlorite. Sodium Hypochlorite is used in household bleach.
While many products contain bleach, not all of them are registered pesticides and therefore are not suitable for treating mold. Instead, consumers should look for products that specifically make claims to be a disinfectant, as such products will be registered as such.
While many organizations in the past have claimed that any type of common bleach is acceptable for killing mold, OSHA and the EPA have begun to realize that this not true.
Safety and Eco-Friendliness
Safety precautions should always be enforced whenever working around mold or mold killers and stain removers.
These safety precautions may include sealing off doorways with plastic and duct tape, ensuring proper ventilation (in some cases using an exhaust fan is recommended), wearing a respirator that is designated to protect against black mold, covering exposed body parts, and disposing of all materials used to clean the mold in a sealed plastic bag (try to avoid carrying the bag through the rest of the house if possible).
How to Apply Mold Remover
- Follow the directions on the bottle carefully.
- Most products will spray on and then need to be allowed to set or dry.
- Depending on the specific product, users may need to do some scrubbing.
- Depending on the specific product, users may need to rinse the product from the surface.

- Use #100-grit sandpaper and sand down the affected area.
