What is mould, and why is it an issue? 

Mould is a basic organism that feeds off of and breaks down organic material. There are many different types of mould. Just your shower alone you may have seen different varieties that appear different in colour, spread and how easily (or not) they clean off.

Mould are a form of fungi, and grows in moist conditions, which is why people also can be susceptible to bodily forms of fungi such as Tinea, on feet where conditions are favourable. Moisture is the main source of growth of mould fungi, which is why moist areas of the home can be more susceptible, such as bathrooms, showers, vanities and basements.

Mould can create a lot of structural damage if it progresses, slowly destroying walls and flooring as it progresses. To spread and colonise areas, mould releases spores. Some people can have allergic reactions to these spores including respiratory and skin reactions. In some cases, especially in the immuno-compromised, it can lead to mould infections of the lungs.

How to clean

Four ingredients are effective in cleaning and controlling mould growth. These are:

  • Water
  • Vinegar (White)
  • Baking Soda
  • Bleach

Vinegar & Baking soda can be mixed, along with water or water with just vinegar or just baking soda. For the more stubborn deposits of mould, a diluted bleach solution of 250mls of bleach in 4 litres of water can be used. Commercial mould sprays are also available with this solution pre-mixed.

Ensure proper contact precautions are used when using bleach or chemicals, as they are irritants, causing skin and breathing irritation. Gloves are recommended at all times, and a face mask should be considered also.

Vigilance, Action & Prevention

The key to eliminating mould and stopping damage in your property is vigilance, action and prevention.

Vigilance is required, as once mould has become widespread, an expert service may be required.

Action is imperative. In early stages, your cleaner, such as Goddess Cleaning Service can remove and maintain small deposits.

Prevention. Why are you getting mould? Mould grows in humidity and moisture, can these elements be controlled to prevent further growth? Are there issues such as a slow leak in a pipe, inadequate ventilation that can be rectified?
