During the winter months when the temperature drops the cool surface of a concrete wall can cause condensation.
Before applying bleach or detergent you need to clean the basement walls.
After scrubbing the wall vacuum the area again with the water extraction vacuum.
But even an inorganic material like concrete can become mildewed when spores begin to grow on dust dirt or old paint on its surface.
While the white powder often found on basement walls and mold are caused by similar conditions they are actually different materials.
Concrete is a poor insulator.
Use a water extraction vacuum to remove any excess water on the surface of the concrete or cinder blocks.
With the help of a sponge wipe the walls and take off the extra dirt from the wall.
