That pattern refers to a common, sometimes eerie growth that appears on walls where there is moisture and warmth.

It can be harsh on some materials, so it is wise to test on a small, inconspicuous area first.

Another effective option for mold removal is white vinegar. Use it in the same way as bleach—mix, spray on the stain, and let it work. To boost the effect, warm water can be added, along with two tablespoons of baking soda. Do not put this mixture in a spray bottle; instead, spread it on the stain and leave it for about half an hour. If the stain is deeply embedded, scrub gently with a soft brush or toothbrush and rinse with hot water. After any treatment, dry the walls thoroughly to prevent further moisture buildup, which can invite mold to return.
