Tips For Reducing, Managing & Removing Mould

Targeting Mould Sunshine Coast

High humidity, especially in January to March on the Sunshine Coast, is the recipe for an unwanted household visitor: MOULD. Suddenly, it’s everywhere.. if you find mould in your home, rest assured – you’re not alone! In this brief article, we take a look at the mould situation. What is mould? What causes it? What are the health issues? And, most importantly, what can we do about it?

What is Mould?

Mould is part of a group of very common organisms called fungi that also include mushrooms and yeast. It is present virtually everywhere, both indoors and outdoors. There are many different types of mould, and they all have the potential to cause health problems. [SRC: health.nsw.gov.au]

What Causes Mould?

The presence of mould is caused by wet, dampness and a lack of ventilation. [SRC: ABC] This makes humid summers on the Sunshine Coast the perfect opportunity for mould to proliferate. Especially in periods of extended rainfall and high humidity, conditions are optimised for the growth of mould inside and outside the home.

What are the Health Issues with Mould?

In order to reproduce, mould produces tiny particles called spores. Spores are carried in the air and may cause health problems if inhaled by people who are sensitive or allergic to them. [SRC: health.nsw.gov.au] Examples of adverse health impacts include:

  • Irritation of the eyes, nose, throat and skin
  • Allergic reaction in people with a mould allergy (e.g. asthma flare-up or hay fever symptoms).
  • Hypersensitivity pneumonitis—a rare lung disease where the lungs become inflamed due to an allergic reaction to certain inhaled substances (e.g. organic dust, fungus, mould or chemicals)
  • Infection.

Most healthy people will not experience health problems from contact with mould, however the risk increases for people with:

  • asthma, allergies or other respiratory conditions may be more sensitive to mould
  • a health condition or undergoing medical treatment that lowers their immunity are more at risk of infection (e.g. cancer and its treatment, organ transplant recipients).

Ensuring Your Air-Conditioner Is Mould-Free

Because we work with air-conditioners, it’s important to point out that regular cleaning of your air-conditioner unit is essential for mould control. Air-conditioners circulate the air you breathe, so it’s essential to ensure that they are clean and free of mould. This is particularly important on the Sunshine Coast, where high humidity, especially after rain, sees an increase in AC usage. We provide a professional clean & service for your split system or ducted air-conditioner. We recommend this service at lease twice a year to ensure your system is running optimally.

Using Dry Mode to Reduce Humidity

Some ducted and split system air conditioning units offer a mode called ‘dry mode’. In addition to their capability to provide heating and cooling for your Sunshine Coast home, this mode can also be used to humidify, dehumidify, ventilate and purify the air. [SRC: Daikin] If you’re consider a new air-conditioner on the Sunshine Coast, it’s a great idea to assess prospective units for this mode. Learn more about new air-conditioners here.

How to Prevent Mould:

Mould is caused by wet, dampness, lack of ventilation and humidity. The trick to preventing mould, or inhibiting its growth, is to prevent these conditions from arising at home. This is easier said than done when it rains incessantly for 5 months; however utilising your air-conditioner or dehumidifier during these times can also be helpful. Here are some handy tips to prevent or inhibit mould at home:

  1. Allow sunlight into your home, as much as possible.
  2. Allow air to circulate. Open doors and windows.
  3. Where does your clothes dryer vent it’s air? If possible, arrange for it to vent outside, as this air can be very humid and if vented inside, can create mould-growing conditions.
  4. Clean wet areas of the home regularly.
  5. Wipe away any moisture you find, and try to keep the inside of the home dry.
  6. Dry and air damp clothes and shoes outside if possible.
  7. Clean carpets and rugs regularly using a HEPA (High Efficiency Particulate Filter) vacuum cleaner.
  8. Clean evaporation trays in air-coolers, dehumidifiers and refrigerators regularly.
  9. Don’t run evaporative air cooling systems with water during high humidity (over 65%). If the air feels humid, run the air cooler without water and open the windows.
  10. Allow space between furniture and walls so air can flow, particularly wardrobes.
  11. Don’t stack boxes or other items against outside walls, especially walls that don’t get a lot of sun.
  12. Place absorbent beads in affected rooms to soak up extra moisture. You can buy these at the supermarket.

How to Remove Mould

  1. Obtain personal protective equipment, including half-face disposable respirators with P1 or P2 filters, to avoid inhaling mould spores when cleaning. You’ll find these at hardware stores.
  2. Place drop sheets on the floor and exclude people from the affected area if they’re not performing the work.
  3. Get 2 buckets: 1 for cleaning solution and 1 for clean water.
  4. Wipe the area clean with a microfibre cloth and cleaning solution. Don’t put dirty cloths back in the solution; rinse them in the clean water to avoid cross-contamination.
  5. After cleaning the area with the solution, wipe the surface with a damp cloth. Use a different cloth to the one you used with the solution.
  6. Wipe the surface dry with a clean cloth.

Making Mould Remover

Here are some tips for removing mould from qld.gov.au. They’re particularly useful because they include different options, so depending on what you have in the kitchen, you may not need to go shopping to get started.

Remove mould using a suitable mould remover, such as:

  • a solution of 3 parts vinegar and 2 parts water
  • a solution of 70% methylated spirits and 30% water
  • a solution of tea tree oil and water
  • commercial products from the supermarket. Follow the safety instructions to protect your eyes and skin.

Mould Removal Tips

Why shouldn’t I clean mould with a dry brush or broom?

This could release spores into the air, which may cause adverse health affects and spread mould to other areas. [SRC: qld.gov.au]

Why shouldn’t I clean mould with bleach?

Using bleach is not recommended because it’s not an effective mould killer. However, bleach will help to eliminate other disease-causing organisms that may be present because of contaminated floodwaters. [SRC: qld.gov.au]

Why should I keep changing cloths when cleaning mould?

Always use a different cloth with each process and throw them away after, or the mould spores will spread and mould will reappear. [SRC: qld.gov.au]

Why should I wear personal protective equipment when cleaning mould?

Our immune system does not like mould. It is not meant to be breathed into our lungs. [SRC: qld.gov.au]

Why Air-Conditioners Should Be Cleaned

Air-Conditioners need to be cleaned on a regular basis. The benefits of regular cleaning include health, efficiency of operation, and longevity of the unit. In this brief article, we expand on this to explain why regular cleaning is essential, and provide some (pretty unpleasant) images of air-conditioners which we have cleaned.

Why Air-Conditioners Should Be Cleaned

There are three main reasons why you should arrange to have your air-conditioner cleaned on a regular basis: health and efficiency.

Health Reasons

If you don’t like reading, just scroll down to the pictures of air-conditioners that we have cleaned lately – they tell the story. Over time, using your air-conditioner creates a build-up of dirt and mould. This is especially important on the Sunshine Coast, where high humidity creates prolific mould in AC units. If they aren’t regularly cleaned, the air you are breathing will be contaminated by this buildup. Breathe clean air, and get your air-conditioner cleaned regularly. Indoor air quality matters! You can learn more about it here.

Efficiency Reasons

A buildup of contaminants such as dirt and mould effects the efficiency of your air-conditioner. As the buildup gets worse, the space for air to move in the system decreases and forces the system to work harder to achieve the same results. This makes the system operate less efficiently and will cost more to run.

Longevity Reasons

Your air-conditioner can enjoy a longer life with regular cleaning. Restricting the airflow in the unit makes the unit work harder which will shorten its lifespan. Keep you AC clean and it will last longer, just like any mechanical device.
