Facts about Mould and Safety Tips

The Myth about Chlorine Bleach

US spelling - mold

 

Some companies advocate the use of Chlorine Beach as a mould remover for remediation projects. We DO NOT use  or recommend chlorine bleach [sodium hypochlorite] to kill mould or disinfect mouldy areas.

  • Chlorine is not an effective or permanent killer of mould or the mould spores and does not address the odours caused by mVOC's (volatile organic compounds) that are released by the live and dying mould.
  • Chlorine bleach is too diluted to permanently kill mould unless the mould is sitting on top of a hard non-cellulose surface*.
  • As chlorine constantly escapes through the plastic walls of its containers, it's effectiveness is further reduced by up to 50% in 90 days in a never opened container.
  • Mould, by nature of the physiology, has a hyphae that extends out from the body of the mould cell. This hyphae can penetrate and intertwine into the fibers of the substrate, in this case, the dry wall or wood, microscopically piercing the surface of these items. The ion structure of the chlorine prevents it from penetrating into those same porous materials.
  • The chlorine stays on the outside surface, while the mould penetrates these materials. The chlorine can never reach into the areas that the hyphae grow. So the mould's hyphae remain untouched and intact. When moisture re-enters the area where the hyphae have embedded themselves, the mould will continue to grow.
  • On most porous building materials that contain, cellulose such as wood timbers, drywall, chipboard, plywood, etc., bleach can change the color of the mould, but will only slow down mould growth for about 3 weeks. It is not a long lasting solution.
  • Chlorine Bleach is not registered with the EPA as a disinfectant to kill mould. On products imported from the USA, an EPA registration number for killing mould is listed on the label of any brand of product that is recognized for that purpose. Chlorine bleach does not have this registration.
  • Beach can also ruin the surface finish on many substances, discolouring fibers and dissolving coatings and tarnishing certain finishes.
  • * A recent study has found that chlorine does have some limited effect on killing mould on some hard surfaces, where the hyphae does not penetrate the surface. These would include ceramic tile, formica counters or steel appliances. However, the chlorine will not address the spores or the odours.
