During the winter months when the temperature drops the cool surface of a concrete wall can cause condensation.
Mold on basement concrete walls.
Mold growth on concrete due to humidity is typically diffuse and spread across a large area.
Before you can begin the mold removal process you must give your concrete basement walls a thorough cleaning.
Take a bar of soap and mix it with water.
Concrete walls are not especially prone to mold and mildew which are words for the same thing.

Before applying bleach or detergent you need to clean the basement walls.
With the help of a sponge wipe the walls and take off the extra dirt from the wall.
While the white powder often found on basement walls and mold are caused by similar conditions they are actually different materials.
But even an inorganic material like concrete can become mildewed when spores begin to grow on dust dirt or old paint on its surface.
Saturate the walls with the peroxide then let it sit for up to 30 minutes.
After scrubbing the wall vacuum the area again with the water extraction vacuum.
Concrete is a poor insulator.
In time this elevated surface moisture creates an environment conducive to mold growth.
Next pour the newly formed cleaning solution into an empty spray bottle and proceed to vigorously apply it to your mold laden basement walls.
Begin this step by combining warm water with a mild brand of soap.
For molds on the surface of the wall mix detergent and water solution and clean the area with a scrub brush.
Both can be cleaned.
Saturate the walls with the peroxide then let it sit for up to 30 minutes.
Mold is a living organism that occurs in wet environments.
