Many households have different all-purpose bleach cleaners and surface disinfectants that will help clean and kill microbes found on hard surfaces. One of the most common components found in bleach is chlorine that has a reputation for being a harsh chemical that does a great job in disinfecting surfaces. Because of this, many homeowners think that it’s an effective solution to treat mold. 

According to the Occupational Health and Safety Administration (OSHA), based on recent examinations, they advise against the use of bleach to exterminate mold. This is why it’s important to hire professionals who can do mold cleanup for you safely and follow health protocols. 

If you’re wondering why you should stay away from chlorine bleach for treating mold issues, keep reading. This article will discuss everything you need to know about mold, chlorine bleach, and better treatment alternatives. 

What is mold, and how does it spread?

Mold is a fungus that loves to grow in high-moisture, warm, and dark environments. On the surface, they can look harmless, sticking on your wall and your home’s hard surfaces. However, they can give you and your family severe health issues and even cause serious damage to your home and water system. 

Another thing you should note about mold is that they have an effective mechanism of reproduction. Mold reproduces by releasing microscopic spores in the air until they land in a suitable environment, such as a wet, dark, and warm surface with a proper food source.

Can chlorine bleach effectively kill mold?

On the surface, while you’re cleaning the affected moldy area, it may seem like chlorine bleach is doing a fine job. However, the results that you get are only short-term because, after some time, you’ll notice that mold will return to that treated area. But why is that? Why can’t chlorine bleach kill mold properly?

The reason chlorine bleach does an awful job at treating mold is that it can’t soak into porous surfaces. This basically means that to effectively kill mold, the roots of the infestations should be killed. However, bleach only kills the surface structure and can’t seep into the surface underneath, making the microscopic roots eventually grow back. 

Besides that, bleach is essentially 90% water. This means that the chloride component will evaporate rapidly when exposed to air, leaving the water behind, and encouraging mold to develop.

What is an effective method to remove mold?

Now that you’re aware that chlorine bleach doesn’t do a great job at eliminating mold, you should find an alternative and safer solution to deal with this issue. 

Ideally, you’ll want to work with mold removal companies to help you with this issue. This is because they’ll have the right tools, products, and equipment to ensure the safe removal of mold in your home. The chemicals they’ll use are strong enough to find its way through porous surfaces, eliminating your mold’s roots. 

After cleaning the affected area, ensure that you allow these surfaces to completely dry to prevent future mold development. And since you’ll work with a mold removal company, they can give you tips on how to avoid mold growth in each area of your home. 


Dealing with mold is incredibly troublesome, time-consuming, and can be pretty expensive if not done right. This is why it’s essential to understand the structure of mold and the best cleaning method to remove them from your home altogether. By working with mold removal companies, you’ll ensure a clean, mold-free home for you and your family.
