How to clean mould from surfaces?: A comprehensive guide

Mould accumulation can be a menace for both indoor and outdoor spaces of your house. The humid climate in most regions of India provides them with the ideal environment to thrive. As a result, they are a common sight in homes.

However, it is also important to note that excessive mould accumulation isn’t just an aesthetic issue, but can also prove to be a serious health hazard. It therefore becomes extremely important to locate mould-affected regions as soon as possible and clean them up. Wondering how to do that? Well, check out this detailed guide to cleaning moulds from your spaces:

 

Common spaces for mould accumulation

It is important to identify moulds as soon as possible to avoid them from becoming a major problem. There are several spaces in your house that are prone to mould accumulation. Here are the most common ones you should keep a regular check on:

Bathroom

Bathrooms are the most humid spaces in your house. This, coupled with poor ventilation, makes them ideal for mould growth. Moulds in bathrooms are commonly found on tiles, shower curtains and around the shower and faucet fixtures.

Basement and store rooms

Basements and other similar storage spaces such as attics that are not used much experience heavy mould accumulation. With limited exposure to sunlight or fresh airflow, the conditions here are suitable for mould growth. Look out for this menace on floors, walls, ceilings and even the objects stored, especially ones with niches and ridges.

Ceilings and wall cavities

Moulds grow most easily in spaces prone to water leaks. Ceilings and wall cavities are the first to be affected by plumbing issues that cause water accumulation, leading to excessive mould growth here.

Plumbing fixtures

Surfaces that come in frequent contact with water are also highly susceptible to mould growth. Keep a check on your plumbing fixtures, especially leaky faucets and drain pipes, as mould growth generally starts from here before spreading to other places.

Ductwork

Another common spot for mould growth is duct spaces that do not receive adequate lighting. Ducts for heating, ventilation and air conditioning (HVAC) should be regularly checked for mould accumulation to ensure proper functioning.

For larger affected surfaces, you might need to rebuild the entire wall. It is best to consult a professional in such cases.

Concrete or stone

Light mould can be removed from stone or concrete surfaces using a simple soap solution. For excessive mould growth, you can go for a white vinegar solution. Irrespective of the cleaner you use, make sure to scrub the affected surface thoroughly.
