Can Bleach Be Used To Kill Mold?

You’ve likely come across mold in either your home or business and felt the urge to tackle it immediately yourself. It’s a common reaction to reach for bleach, under the assumption that it’s a cure-all solution. But is using bleach really an effective method for mold removal?

Using bleach for mold removal is not recommended. Although it may seem like a quick solution, bleach is not the most effective way to kill fungi. More importantly, it poses health risks due to the release of toxic fumes when used in this manner.

Microbe Solutions offers a safer and more effective alternative for addressing mold issues. Our disinfecting and sanitizing services include the removal and prevention of harmful pathogens, including mold. By first disinfecting the area and then applying our environmentally safe, non-toxic Biostatic formula, Common Sense Fresh Start, we provide lasting protection against mold and odor without the health risks associated with bleach.

The use of bleach for mold control

Using a bleach solution to kill and remove mold is not an accepted practice for certified mold remediators. Why? Bleach appears to kill mold because after it is applied, the mold disappears. In fact, it makes it disappear by simply bleaching it.

As mold begins to form and spread, it forms tiny “roots” that will go into the surface of most materials that it forms on. EPA approved products for mold will reach these roots and kill the mold, preventing it from reforming. They are typically safe for most surfaces when used properly and the “Ready To Use” (RTU)’ products do not require the user to dilute the product. These can be used right out of the container. EPA approved products typically are low in VOC’s making them safe to use with proper personal protection equipment. Always follow the directions on the label to ensure your safety when using any disinfectant.

Using Bleach to Kill Mold Can Be Dangerous

  • Bleach, on the other hand, will have high volatile organic compounds (VOCs) that can potentially cause irritation to the lungs when the toxic chlorine gas is inhaled.
  • Bleach is caustic in nature and can most certainly damage the surface of whatever it is being applied to.
  • The EPA has not approved bleach for use as a mold killer or a deterrent. For that reason alone, it should not be used for mold control.
  • Moreover, there are no recommendations for personal protection gear when using bleach.

Prolonged exposure to household bleach may cause irritation to the eyes, mouth, lungs, and skin. The EPA recommends to always ventilate the area and vent the air outside if you decide to apply disinfectants or biocides. Never combine cleaning solutions containing ammonia or detergents containing chlorine bleach because hazardous fumes may be created.

What Products Should Be Used To Kill Mold?

We have used many products over the years in our company and have a few “go to” products that are extremely safe and effective. Our most used disinfectant for mold remediation is Smart Touch. It is EPA registered and a “Ready To Use” product.  The directions are very easy to follow and cost effective. Smart Touch is non-toxic but very good at eradicating mold when applied to a moldy surface according to the instructions.

Once the mold has been removed using EPA mold removal products, it’s important to protect the surfaces in your home and business from future mold growth and development. Additionally, we have developed a mold inhibitor that is also EPA registered. When applied, it will not allow odor causing bacteria, mold, algae, fungi, or mildew growth. We call this product Common Sense Surface Protectant. When this products is applied it dries and chemically bonds to the surface. This protective coating is not washed away with soap and water and lasts over an extended period of time.

Resolve the Moisture Problem

Mold and its spores can be found almost anywhere, but active mold growth requires moisture. Even after mold is removed from an area, spores may be left behind. If the moisture problem is resolved, they will not be able to grow and colonize. It’s important to address and removed the source of the moisture problem so that the environment is no longer conducive to mold growth. Avoid allowing consistently damp conditions so that mold is not reintroduced to the area once it has been removed.

Get Professional Mold Remediation Help

In the long term, you should consult a professional to assess any mold issues you may have. Cleaning mold won’t completely get rid of the negative effects because they can still release hazardous spores after it’s dead. Mold must be completely eradicated, and depending on the kind of surface the mold has grown on, there are different methods for doing so.

Additionally, the air quality should be tested and restored for the sake of the people who spend time in that space. If you have any mold issues in your house, consider calling in a mold remediation specialist to achieve a mold free home or business.

Mold Prevention Tips

At Microbe Solutions, we understand the importance of creating a mold-free environment in your home, and we’re here to help you achieve that goal. Here are some valuable tips and precautions to stop mold from thriving and growing in your house:

  • Ensure Proper Ventilation: Install ventilation fans in areas like the kitchen, bathroom, and any other rooms with water sources. Proper ventilation helps reduce moisture levels, making it harder for mold to grow.
  • Control Humidity: Maintain the humidity in your house below 50% by using a dehumidifier or an air conditioner. Lower humidity levels discourage mold growth and create a more comfortable living space.
  • Keep Your Home Clean and Dry: Regularly clean and dry your home to prevent mold from finding a suitable environment to grow and spread.
  • Address Water-Related Issues: Take care of all water-related problems promptly, such as fixing dripping faucets, leaky roofs, and damp basements. These issues provide the moisture mold needs to survive.
  • Avoid Carpets in Damp Areas: Refrain from using carpets in areas prone to moisture, like bathrooms and kitchens, as they can become damp and foster mold growth.
  • Dry Wet Rugs and Mats: If area rugs or mats get wet, ensure they are thoroughly dried to prevent mold development. Mold stains not only look unpleasant but can also damage surfaces and structures.

Frequently Asked Questions

Q: Does bleach kill black mold?

A: Bleach is commonly considered a solution for removing mold due to its powerful disinfectant properties. However, when it comes to black mold specifically, the efficacy of bleach is subject to certain limitations and considerations.

Black mold, also known as Stachybotrys chartarum, can pose serious health risks and requires effective treatment for removal. While bleach can kill surface mold on non-porous materials like tiles and bathtubs, it’s not effective on porous surfaces such as drywall or wood. This is because bleach cannot penetrate these materials deeply enough to kill the mold’s roots, leading to potential regrowth.

Furthermore, using bleach on black mold can present health hazards of its own, including the release of toxic fumes that can irritate the eyes, skin, and respiratory system. It’s also important to note that the application of bleach might lead to a false sense of resolution, as it may only remove the color from the mold, making it invisible without addressing the underlying problem.

For lasting results and to tackle the root cause of black mold, it’s recommended to use products specifically designed for mold remediation, which can deeply penetrate porous surfaces to eliminate mold at its source. Additionally, addressing the moisture or humidity issues that facilitate mold growth is crucial for preventing future infestations.

In light of these considerations, it’s advisable to seek professional assistance for severe mold issues. Services like Microbe Solutions offer comprehensive disinfecting and sanitizing solutions, including environmentally safe, non-toxic treatments that provide long-lasting protection against a wide range of pathogens, including molds. Their Biostatic formula, for instance, not only eliminates existing contamination but also prevents future growth, offering a more effective and health-conscious alternative to conventional methods like bleach.

Q: What kills black mold instantly?

A: When addressing the challenge of eliminating black mold, it’s crucial to approach the issue with effective and reliable solutions. Black mold, scientifically known as Stachybotrys chartarum, is notorious for its resilience and potential health risks. While the idea of an instant kill is appealing, it’s important to understand that effectively dealing with black mold involves a combination of immediate action and long-term prevention.

For an immediate impact on black mold, especially on non-porous surfaces, solutions containing hydrogen peroxide, vinegar, or commercial mold removers specifically formulated for black mold can be effective. These substances can kill the mold spores on contact. However, it’s vital to note that merely killing mold spores doesn’t address the root cause of mold growth or prevent its recurrence.

This is where the specialized services offered by Microbe Solutions come into play. Our approach goes beyond the superficial elimination of mold. Initially, our disinfecting process targets and removes existing mold, bacteria, viruses, fungi, and other harmful pathogens. This step is crucial for mitigating the immediate concern of black mold infestation.
