Bleach and Mold the hard truth!

5/11/2016 (Permalink)

Bleach does not kill mold on porous surfaces. Mold grows in colonies and has roots which grow deep into the material. The bleach will infact kill the surface mold however the water content of the bleach will seep into the porous structure and provide a food source to the roots. This will actually cause the mold to grow back stronger.

Here are some facts about Bleach and Mold

  • The Clorox ® Company, EPA and OSHA have specifically advised that Bleach should not be used in mold remediation
  • Bleach does not kill mold, it will only remove the stain caused by mold
  • Bleach in some cases will allow toxic mold to grow where it was not present before
  • Bleach itself is considered to be toxic and is classified the same as gasoline
  • Bleach on gypsum (the material found in sheet rock or drywall) will emit chlorine gas for at least a week
  • Bleach applied to wood will push spores deeper into the wood fibers creating more problems later
  • Bleach does more harm than good
