Mould is more than just an unsightly nuisance. It poses real risks to your health and the wellbeing of your household. As awareness grows around the dangers of harsh chemical cleaners, many people are seeking natural alternatives to keep homes clean and safe.
We explore the most effective natural mould removers, each offering a unique approach to banishing mould while supporting a healthy home.
The dangers of mould
Mould thrives in damp, poorly ventilated spaces. When it grows indoors, it releases spores and toxins that can trigger allergies, worsen asthma and cause respiratory problems, especially in children, the elderly, and those with weakened immune systems.
Beyond health risks, mould can damage building materials, stain surfaces, and create unpleasant odours, making prompt and safe removal essential for any home.
The best natural mould removers
1. White vinegar
Vinegar is a staple in natural cleaning, prized for its antifungal and antibacterial properties. Unlike bleach, which only masks mould by whitening it, vinegar penetrates surfaces to kill mould spores at their source, helping to prevent regrowth. This makes vinegar a reliable and affordable choice for ongoing mould control.
To use, simply pour the white vinegar into a spray bottle and apply it directly to the affected area. Let it sit for at least one hour before wiping or scrubbing away the mould. The strong scent will dissipate as the vinegar dries, leaving your space fresh and clean.
Vinegar can be further enhanced by adding essential oils. Tea tree and lemon oil are both ideal, as they have their own antifungal and antiseptic benefits, as well as a pleasant scent.
2. Tea tree oil
Tea tree oil is a potent natural remedy with antimicrobial properties. Studies have shown that tea tree oil is more effective at inhibiting mould growth than vinegar, alcohol, and some commercial cleaners, thanks to its high terpinen-4-ol content.
To make a tea tree oil mould remover, mix two teaspoons of tea tree oil with two cups of water or distilled white vinegar in a spray bottle. Spray the solution generously onto the mould-affected area, allowing it to soak in for at least an hour. For stubborn stops, multiple applications and some scrubbing may be needed. Tea tree oil is perfect for both solid and porous surfaces, making it versatile for use on everything from tiles to fabric. While the scent is strong, it is not harmful and will fade over time, leaving your home mould-free and naturally deodorised.
3. Baking soda
Baking soda is a gentle yet effective solution for tackling household mould. Its mild abrasive quality helps physically remove mould, while its antimicrobial properties help to inhibit further growth.
To use baking soda, mix it with water to form a paste and apply it directly to the mouldy area. Let it sit for at least 10 minutes before scrubbing and rinsing. For ongoing prevention, dissolve baking soda in water and spray it onto surfaces after cleaning.
Baking soda is non-toxic, making it ideal for use around children and pets. It also helps neutralise odours, leaving your home smelling clean and fresh while keeping mould at bay.
4. Hydrogen peroxide
Hydrogen peroxide is a common household disinfectant with powerful antifungal activity. It is especially effective at killing mould on hard, non-porous surfaces, making it a go-to option for bathrooms, kitchens, and tiles.
To use, pour 3% hydrogen peroxide into a spray bottle and saturate the mouldy area. Allow it to sit for at least 10 minutes, then scrub and wipe clean. Hydrogen peroxide breaks down into water and oxygen, leaving no toxic residue behind.
While hydrogen peroxide is less effective on porous materials, it excels at disinfecting and removing surface mould. It is also odourless and safe for most surfaces, though it may cause slight bleaching on some materials, so always test in an inconspicuous spot first.
5. Grapefruit seed extract
Grapefruit seed extract is a lesser-known but highly effective natural mould remover. As it contains compounds that target and eliminate mould, bacteria and yeasts, it makes a powerful addition to your cleaning arsenal. Be sure to find one with minimal processing and no added chemicals.
To use, mix ten drops of grapefruit seed extract with one cup of water in a spray bottle. Spray the solution onto the mould and let it sit for 10 to 15 minutes before scrubbing. Leaving some of the solution to dry on the surface can help prevent future mould growth.
How to prevent mould
Preventing mould is far easier and healthier than dealing with an outbreak. Two of the most effective strategies for mould prevention are proper insulation and adequate ventilation. Insulation acts as a barrier between the warm interior of your home and the cooler outside air. Ventilation is equally crucial as it allows humid air to escape and fresh air to circulate. Without proper airflow, moisture can become trapped indoors, raising humidity levels and increasing the risk of mould. Simple measures like opening windows daily, running a dehumidifier and using extractor fans in kitchens and bathrooms make all the difference.
Combining effective insulation and ventilation creates a home environment less hospitable to mould, supporting the health of everyone who lives there.
