What Is White Mold
White mold is often found in cool, damp environments such as in basements on walls and other structures. It is often confused with efflorescence, which is a mineral deposit that forms on foundation walls and other masonry surfaces due to water seepage. You can test to see if its mold by spraying it with water. If it dissolves, it is a mineral deposit if it does not, then its most likely white mold.
Cleaning Mold On Basement Walls
Basements are usually dark areas, with poor ventilation, and tend to have higher than normal humidity. Under these favorable living conditions, mold will grow rapidly and thrive. Mold can come in a variety of colors, from black to white, and from blue to green. Molds color and type are not too important. What is important is getting rid of it. Successful cleaning of mold on basement walls can be difficult unless the causes allowing for mold growth are first addressed. Foundation leaks, caused by years of wear and cracks in walls and floors, along with condensation on plumbing and HVAC pipes and vents, tend to help maintain humidity levels that are higher than those normally found in above ground areas of the home. Another reason that cleaning mold on basement walls is difficult is due to the porous, rough surface of concrete. Its hard to reach deep into all the tiny crevices and pores.
When you see mold on basement walls, the mold is not growing on the concrete or the concrete blocks. Mold cannot eat concrete because concrete is not an organic substance. Organics, along with moisture, are some of molds requirements to grow to survive. Usually the mold is growing on dirt and dust or paint and wall coverings that contain organic components. Many paints are latex-based and latex is an organic compound.

S To Clean Mold On Basement Walls
When it comes to cleaning mold on basement walls, scrubbing with detergent and water is the first step. Vacuum or sweep down the walls to remove as much dry material as possible. After that, washing down the walls with soap and water will help remove most of the remaining dust and dirt that has accumulated. Many so-called experts will tell you that a bleach and water solution will work. The thing is, we want to remove the mold, not just kill it. Remember, extreme caution must be taken when using chlorine bleach in an enclosed, poorly ventilated area. The fumes from bleach can easily overwhelm if you dont take the proper measures to protect yourself. Opening windows and wearing a respirator is highly recommended.
Because of the chemical nature of bleach, it is hard to work it into the concretes pores. In addition, bleach manufacturers only recommend using bleach on non-porous surfaces. Rub your hand over a concrete wall. It is definitely porous. Also bleach can be corrosive and can cause further damage. Yet another reason to avoid using chlorine bleach is that when bleach comes into contact with organic materials, the organics tend to render the disinfectant qualities of the bleach ineffective. Bleach always works best on clean, non-porous surfaces.
What Does Mold On Concrete Look Like
Mold on concrete can look like any number of different things. It depends on what classification of mold is growing on the surface of your concrete. It could be white, black or green.

Mold On Concrete Walls
Black fungi on concrete walls mostly comes from moisture hitting and being absorbed into the wall. Before attempting to clean the walls, first resolve the moisture issue by redirecting downspouts and swamps from the wall. You could also try installing an interior footing drain to keep the water from the wall. Fix all water seepage from hose spots and taps. Also raising relative humidity in the house by improving ventilation would do the trick. You will then proceed to clean the molded concrete walls after fixing the moisture issue.
Ammonia Can Clean Concrete Walls
Ammonia is another cleanser that works really well on concrete walls. It dissolves grease and grime quickly and is perfectly safe to use on concrete. Its also effective at cleaning and killing mold.
To make an ammonia-based concrete cleaner, do the following:
- Dish detergent
- A stiff nylon brush
- Spray Bottle
In a bucket, combine 14 cup ammonia, a few squirts of detergent, and water. Mix them together to produce the cleaning solution. First, clean the wall of loose dust and dirt with a rag, feather duster or vacuum. Then use some soap and water to clean the basic dirt stains off. Next, scrub the solution from one end of your wall to the other with the nylon brush until youve coated the entire surface. After that, clean the wall with a hose and a clean towel.
Make sure your basement is well ventilated when working with ammonia. I recommend using safety equipment like gloves, goggles and a mask too.

Black Or Gray Concrete Stains
Black or gray spots on your walls are generally mold. This is something you should be worried about because mold can be harmful to your health.
Mold typically grows in damp, warm settings. If that describes your basement then bring in some airflow to dry it out. I install basement ventilation in pretty much every basement we work on just to prevent mold growth. Fresh outside air is great at drying out those damp walls.
Try to maintain low humidity. If moisture can accumulate on the concrete walls or floors it could start growing mold.
Luckily, cleaning and killing mold spores isnt that hard once you find them. First, use a soap and water solution to clean all the surface mold. Soak the walls with water and then wipe the mold with a rag. Itll come off easily. But this initial cleaning is only surface level. Once youre done you have to clean deep to kill the spores.
After the wall has dried, mix some bleach in a bucket of fresh water. I use 1 about part bleach for every 3 parts water. Soak the wall in the bleach solution for about 20 minutes. Get the concrete really wet so that it gets into the pores. Dry the wall thoroughly when done.
You can substitute vinegar for bleach if you prefer. It work about the same but isnt as harsh. Keep the ratio of 1 part vinegar to 3 parts water.
For really bad mold, try a commercial mold killer.
