Why can't I use bleach on wall mold?
Facts About Mold Growth
Understanding Mold
Minute mold and fungus spores exist all over the place, outside and inside, making it difficult to expel all mold from a home.
As soon as the mold spore is in contact with moisture it will begin to lay down roots spread into a colony. Bleach will only remove the surface mold but it will not get rid of the root system. As soon as it receives moisture again it will grow again.
