This article will guide you on how to remove mould from walls and ceilings of your home, as it needs immediate action to avoid further damage.

Mould is the broader term used to refer to a species of microscopic fungi. Mildew is a term that essentially refers to a sub-category of mould. Hence, before starting with how to get rid of mould on walls permanently, you should know what mould and mildew are.

1. Mildew

Mildew is a type of fungus that can be found on the surfaces of moist places like kitchens and bathrooms. It has a white or grey colour and a powdery, fluffy texture. Being a surface fungus, mildew is much easier to clean and does not structurally damage your house. It can be cleaned with the help of scrubs and run-of-the-mill cleaning products.

Mould is a much more extensive infestation that spreads through airborne fungal spores. It is much slimier and fuzzier than mildew and can be yellow, green, blue or black. Mould causes not only structural damage to your house but also has adverse health effects.

Here is a list of the different types of mould:

• White Mould: Found in cold, damp places like basements.

• Green Mould: Found in moist places like shower walls and corners.

• Blue Mould: Primarily found in bathroom ceilings and walls.

• Black Mould: Found in houses with excess moisture and water damage.

Bleach and white vinegar are the 2 best cleaning solutions to remove mould from walls and ceilings.

Chlorine bleach is a great cleaning agent that helps sanitise ceilings and walls by eliminating mould and killing bacteria.

Step 1: To clean with bleach, you need to gather the following materials:

Step 6: Once the ceilings and walls are mould-free, you must dry out the cleaned areas.

Step 7: Use a clean and dry rag and press or dab it against all the areas you cleaned.

Step 8: Do not use water to clean the ceilings and walls, as water may also wipe off the bleach, a preventative measure against mould growth in the future.

2. Using White Vinegar

Some people prefer white vinegar over chlorine bleach since it is chemical-free, therefore completely safe to use, and a natural cleaning agent.

Step 1: Gather the following items to get started with the cleaning process:

• Towels, rags and a scrubbing brush
• A spray bottle and water
• Distilled white vinegar

Step 2: Pour some white vinegar into the spraying bottle and spray it well on the mould-affected areas.

Step 3: Allow the vinegar to remain applied to the affected areas for about an hour or so.

Step 4: Soak the clean rags in water and use it to wipe the vinegar-covered mould-infested areas.

Step 5: You can scrub the areas that have stubborn stains and fungi with the scrubbing brush.

Step 6: Press or dab dry towels against the affected areas to clean the leftover moisture.

Step 7: You may keep windows open for ventilation, which dries the area quickly and removes the smell of vinegar.
