Why Bleach Doesn’t Work to Kill Mold
Bleach works to remove the appearance of mold, but it doesn’t kill it. This is because mold has a “branching, thread-like” root system known as mycelium.
When you use bleach to clean, you typically create a solution of bleach diluted with water. The mold problem recurs because the bleach itself evaporates away very quickly, leaving the water to soak back into the wood or other porous surface, rehydrating the mycelium and encouraging the mold to come back. Even, the Environmental Protection Agency (EPA) doesn’t recommend using bleach for routine mold cleanup.
