. As early as the beginning of last century, bleach has been seen as the first mode of attack for mold. There is no question that it is excellent at removing color. But how effective is it when it comes to actually killing mold and preventing its occurrence in the future? The truth is that according to mold removal New York City contractors, bleach is extremely dilute and therefore too weak to actually kill mold. However if the mold is readily accessible such as on a flat surface; then it may prove effective on long-standing. In this situation the bleach can be poured directly on the affected surface and allowed to sit for a while, in which case it might prove effective. But for any mold infestation that has penetrated any surfaces of your home; then there is very little that bleach can do towards killing the mold.
Most mold removal New York City contractors will advise you that once the bleach has sat in warehouses and on store shelves for an extended period of time, the efficacy of the beach gets greatly reduced. In fact, in a matter of just three months, the effectiveness of beach can be reduced by half. This is because chlorine which makes up a large part of the beach tends to escape the plastic container in which it is stored even if the seal is tight. So according to most mold removal New York City contractors, only fresh bleach has any potency as far as mold destruction is concerned.
Another reason that mold removal New York City contractors question the efficacy of mold is the inability to penetrate porous materials that mold usually grows on such as drywall or wood. Bleach is found to remain on the surface and not make its way past hard surfaces to destroy the mold with it. The truth is that, the water in the bleach will penetrate the surface but not the beach itself. In fact mold removal New York City contractors warn that the water from the bleach can penetrate the surface and further exacerbate the mold problem by providing the mold its much-needed moisture source.
Any good mold removal New York City contractors know that bleach is not registered by the Environmental Protection Agency as a mold killer. The mold removal New York City contractors therefore use biocides that have greater penetrative powers than bleach.
