Hey, not an exciting topic…we’ll grant you that; but on the eastern seaboard of Australia, we generally experience reasonably high levels of rainfall, particularly in inclement weather, and when combined with humid conditions, many properties can breed mould.

Mould grows in damp, dull and poorly ventilated spaces such as some kitchens, bathrooms and laundries. Dust and dirt in these areas also helps mould breed. Mould is not only unsightly and can cause permanent damage; but it is also bad for your health and needs to be removed and prevented.


  • Open doors and windows to allow air to circulate, particularly in the bathroom during cool weather. • Keep bathroom walls, showers, shower curtains, baths and basins as dry as possible – open the door to allow air to circulate through the room.
  • Clean your bathroom and property regularly. Wipe away moisture on windows and walls to keep them dry.
  • Allow sunlight into the property as much as possible, especially in the bathroom, laundry and kitchen.
  • Wash and dry damp clothes, and dry and air damp shoes outside as soon as possible. Make sure clothes and shoes are dry before putting them away in a wardrobe. Leave wardrobe doors open where possible.
  • Remove fruit and vegetables from plastic wrapping and refrigerate within 72 hours. Discard mouldy fruits and vegetables. Keep fresh food in sealed containers.
  • Evaporation trays in air-conditioners, dehumidifiers, and refrigerators should be cleaned frequently. • Do not run evaporative air-conditioning systems with water during times of high humidity (over 65%). If the air is feeling humid, run the evaporative air-conditioning system without water. Always ensure windows are open when running an evaporative air-conditioning system.
  • Regularly clean carpets and rugs to prevent mould spores using a High Efficiency Particulate Air (HEPA) filter vacuum cleaner. Most new vacuum cleaners include HEPA filters.
  • If water leaks or spills occur indoors, it is important to clean and dry the area immediately or preferably within 24-48 hours to prevent mould from growing.
  • Ensure the property does not have any water leaks that are visible.



  • Personal protective equipment, including half-face disposable respirators with P1 or P2 filters (available at hardware stores), and should be used to avoid possible mould spore inhalation.
  • Take additional precautions to prevent mould spore release and transmission by using of drop sheets and excluding persons not performing the work from the area that is being cleaned.
  • Remove mould by using a suitable mould remover – there are homemade options online or purchase a commercial-grade one from a supermarket or hardware store.
  • Ensure that you comply with the safety precautions provided by the manufacturer to protect your eyes and skin from the solution or mould remover.
  • Wipe clean the affected area using a microfibre cloth with the cleaning solution. Use a two-bucket system – one bucket with the solution and the other with clean water. Do not put the dirty cloth back in the solution – wash in the clean water bucket first. This avoids cross contamination.
  • After cleaning the mould-affected areas with the solution, wipe the surfaces with a damp cloth. Do not use the same cloth used with the solution. Wipe all surfaces dry with a clean cloth.
  • It is important to use a different cloth with each process and dispose of them immediately, otherwise the mould spores will be spread, and mould will reappear in a short time.
  • Do not attempt to dry brush the area using a broom or brush as this can increase spread of mould.
