Will Bleach Kill Mould?


Will Bleach Kill Mould? Mould Removal Sydney and Brisbane 

It is a common misconception killing mould with bleach works. Killing mould with bleach is ineffective as it often doesn’t stop the actual cause of the mould growth. 

Mould cleaning is an important process due to the health risks associated with exposure to mould spores. However, mould remediation and treatment processes depend on if the mould is growing on a porous or non-porous material. Porous surfaces can be penetrated by mould, meaning that the mould ‘roots’ can stay alive due to the difficulties in exposing, treating and removing mould that is deeper than surface level. Therefore, professional mould removal is recommended – especially for areas like Sydney and Brisbane which have lots of warm and wet weather. 

Unlike mould, bleach cannot penetrate porous materials. Therefore, killing bleach with mould doesn’t really kill it. Rather than working as a mould cleaner, bleach can instead remove the colour of the mould which creates an illusion that the mould outbreak has been properly treated. With the visual appearance of mould being one of the most obvious issue indicators, mould with no colour due to bleaching means that the mould can continue to spread undetected. 

In addition, killing mould with bleach can destroy the materials it’s used on, such as wood, leather, tile grout and stainless steel, creating more spaces for mould to grow and hide. While mould exposure is not healthy, prolonged exposure to bleach and other DIY mould cleaning chemicals can also generate health risks.   

Because of all of this, AllAces cannot recommend the use of bleach as a mould cleaner. At AllAces Cleaning and Restoration, we use hydroxyl machines that harness UV rays, like what the sun produces, to eliminate and kill mould and its spores naturally and effectively. We also use air scrubbers to filter the air, as the mould is disturbed during treatment, to prevent further mould spores from spreading and kill off anything else that might remain.  



Where Does Mould Grow? 

Mould grows when an environment is dark, warm and damp. Common places include bathrooms, showers, kitchens, roofs etc. This mould growth can be explained by: 

  • Water damage 
  • Bad/no ventilation or airflow 
  • Minimal sunlight 
  • Flooding 
  • Hot & wet weather 

Like a plant, these conditions are the perfect environment for mould growth. AllAces Cleaning and Restoration offer mould removal in Sydney and Brisbane, as NSW and QLD generally have ideal mould weather conditions with warm and wet summers. 

Will Mould Die on Its Own? 

No, mould will not die on its own. Mould cleaning services are needed to ensure that mould growth is stopped at the source and fully eliminated. Our mould remediation services are a different process from killing mould with bleach, in that we use hydroxyl machines and air scrubbers which do not use harmful chemicals.

Can Mould Make You Sick? 

Yes, mould exposure, especially at high levels, can be dangerous as you are breathing in the mould spores into your lungs. This can lead to symptoms like: 

  • Allergies 
  • Asthma attacks 
  • Headaches 
  • Infections 
  • Coughing fits 
  • Shortness of breath 
  • Fatigue and dizziness 

However, mould cleaners like our technicians at AllAces can come into your home or business with our equipment and remove any mould that lingers in the air, impacting your health.
