Mould can be a persistent and unwelcome guest in any home, thriving in damp and poorly ventilated areas.

Left unchecked, mould can cause significant damage to property and pose health risks. Living in a house with mould can trigger nasal congestion, sneezing, coughing, wheezing, respiratory infections, and worsen asthma and allergic conditions. 

Fortunately, there are several effective methods to combat pesky mould growth and restore a healthy environment.

Here are five proven strategies to kill mould and keep it from making a U-turn in your home

White vinegar

White vinegar is a powerful, natural cleaner that can effectively kill mould on non-porous surfaces. Its acidity helps break down mould spores and prevent their return.

How to use: Mix equal parts of white vinegar and water in a spray bottle. Apply the solution directly to the mouldy area and let it sit for about an hour. Afterwards, scrub the area with a brush or sponge and rinse with water. This method is particularly useful for cleaning mould from tiles, glass, and countertops.

It does not have the most pleasant smell, so feel free to mix it with a essential oil/ fragrance of your choice.

Hydrogen peroxide

Hydrogen peroxide is another excellent mould-killing agent, thanks to its antifungal properties. It can be used on both porous and non-porous surfaces.

How to use: For effective use, pour 3 per cent hydrogen peroxide into a spray bottle and apply it directly to the mouldy area. Allow it to sit for 10-15 minutes, then scrub the area with a brush. After scrubbing, wipe the surface with a clean cloth and allow it to dry completely. This method is particularly effective for removing mould from fabrics and grout.

Baking soda

Old faithful!

Baking soda is a versatile and mild abrasive that can help eliminate mould and deodorise affected areas. To use baking soda for mould removal, mix a quarter of a tablespoon of baking soda with water to create a paste.

How to use: Apply the paste to the mouldy surface and scrub with a brush. For stubborn mould, sprinkle baking soda directly on the affected area and scrub with a brush or sponge. Rinse the area with water, then wipe clean with a damp cloth. This method works well on various surfaces, including walls and carpets.

Dehumidifier

Keeping the humidity levels in your home low is a proactive measure to prevent mould growth. Mold thrives in environments with high humidity, typically above 60 per cent. A dehumidifier can help regulate moisture levels, making it more difficult for mould to establish itself.

How to use: Place a dehumidifier in damp areas such as basements or bathrooms, and set it to maintain humidity levels between 30-50 per cent. Regularly empty and clean the dehumidifier to ensure it operates efficiently.

Home checks and improving ventilation

Preventing mould growth is often about addressing the root causes. Water leaks and poor ventilation can create the ideal conditions for mould proliferation. Inspect your home for any leaks in pipes, roofs, or walls, and repair them promptly.

Additionally, ensure your home is well-ventilated to allow moisture to escape. Use exhaust fans in high-moisture areas like bathrooms and kitchens, and open windows whenever possible to improve airflow.

If mould covers a large area or persists despite your efforts, it may be necessary to seek professional help to ensure a thorough and safe remediation. Keeping your home dry and well-ventilated is key to maintaining a healthy living environment.
