This makes cleaningwith bleach an effective way to kill germs and bacteria because they dont havethe means to reproduce outside of a host.

Mold is much more complicated than that. Hence why it causes far greater destruction than a virus. Mold is a naturally occurring airborne fungus that aids in the decomposition of organic materials. If you have mold growing in your home, you also have mold spores in the air. Instead of an animal or human host, mold lives on organic material and moisture. .

Since moldspores can soak into a surface, mold can outrun bleach. A virus or bacteriacant do that because they live on surfaces. So if you catch a mold spore atthe right moment, bleach MAY be able to remove it but it could also cause someother issues along the way. Read on

Can Bleach Lead To Further Mold Growth

Bleach constitutes 90% water, and since molds need moisture to thrive, it might lead to further growth. When bleach is applied on porous surfaces containing molds, the chlorine contents dry within seconds, leaving water on the surface. This water will be sucked into the porous surface, reaching the molds roots. If you have been wondering why the mold situation in your home gets worse after applying bleach instead of lessening, now you have your answer. Moreover, the bleach might cause mold to grow in areas that were not infested previously.

After prolonged use, bleach will become ineffective in cleaning and treating molds. The substances might get resistant to bleach, leading to ineffectiveness. The only long-term solution to cleaning mold is through professional companies. For molds to go away completely, they must be removed from the roots and spores cleared off. This is the only way the air quality in your home will become better.

Does Bleach Destroy Wood

How to Remove Mold From a Toilet Tank

Our corporate headquarters is located near the Great Smokie Mountains, and we have lots of log home cabins in the area. It seems many people clean their log cabins with bleach before applying finishes. This is a big no no according to Perma-Chink® Systems, Inc. the maker of a product called Lifeline. Here is what they say about bleach and its effect on lignin.

“Chlorine bleach destroys lignin, a component of wood that hardens and strengthens the cell walls. Once the surface cellular structure loses its integrity, film-forming finishes like Lifeline have no sound wood to bond to, and can peel off.” Read article.

If bleach can do that to log cabins, I imagine spraying bleach on the wood in your crawl space is not good. The destruction of lignin will weaken your joists and subfloors and can lead to the need for replacement.

Bleach Will Not Work On Porous Materials

Experienced mold removal specialists understand that the most effective way to deal with mold is to first find the moisture source and make sure it is fixed.

The next step is to remove the mold contaminated porous materials.

Proper removal of mold contaminated materials like drywall, carpet, soft goods, insulation, and other porous materials is essential because mold has hyphae, which are basically roots that embed themselves in the material.

Bleach only removes the color from mold. After you spray bleach, only the surface appears clean. But the problem is, the molds roots, or hyphae, continue to grow. This is the reason that bleach does not work. Bleach may kill some of the surface mold, but it will not be able to penetrate and kill the roots.

In fact, bleach encourages toxic mold growth on porous surfaces because it provides excess moisture. Bleach contains about 90% water. Spraying this is counter-productive because water is an essential ingredient mold needs to grow. When you apply bleach to a surface, the chlorine quickly evaporates leaving behind a lot of water. Then, when the water soaks into porous surfaces like wood, it encourages mold growth. So, bleach can actually make your mold problem worse.

Causes Of Growing Mold In Fabrics

Sometimes you may notice mold on your walls and tiles and dont bother to pay attention to it. However, this matter shouldnt be neglected. Like walls, mold can grow on your fabrics and affect your wellbeing. Surprisingly, mold can trigger allergic reactions and weaken the bodys immune system.

Humid weather is another reason behind mold growth. Therefore, always keep the humidity level of your house below 50%. Mold can grow massively in an above 50% humid environment.

    Tip On How To Get Rid Of Mold On Wood Using Bleach

    In extreme cases or the case of untreated wood, mold can penetrate the wood and make itself at home. If it penetrates, you will need a stronger cleaner something more than just soap and water to clean outdoor wood furniture.

    You can make up as much or as little of this powerful cleaning solution as you would like, as long as you keep the parts the same. In a big bucket mix together all three ingredients. Apply the bleach solution to the wood using a stiff-bristled brush or a scrubbing sponge. After scrubbing the wood, allow it to air-dry.

    Use dehumidifiers and fans to help speed up the drying process, but allow the wood to dry for at least three days. Inspect the wood for any signs of mold, and look and smell the wood. If mold is still present, your best mold remediation is to clean with the bleach solution again.

    Once you know its is no longer present, seal the wood with a primer or pigmented shellac from your local hardware stores. If mold is still present or you notice mold stains, your only other option is to sand the wood. Using sandpaper to sand down the wood allows you to reach the mold or stains that are deep inside.

    You dont want to do a quick sanding instead, slowly sand the wood until either the mold or the mold stains are gone. Once gone, you should stain, paint, or treat the wood to help prevent future problems.
