Cleaning Mould Off Walls with Baking Soda: Easy Natural Solution

Mould on walls isn’t just unsightly—it poses health risks and thrives in damp environments. But with baking soda, a simple and effective natural remedy, you can safely eliminate mould without harsh chemicals.

Baking soda’s mild abrasiveness and antifungal properties make it an ideal cleaner for mould removal. Start by mixing equal parts baking soda and water into a thick paste. Apply it directly to mould spots using a soft brush or sponge, letting it sit for 15–20 minutes to penetrate and break down fungal cells. Gently scrub with a non-scratch cloth, then rinse thoroughly with clean water. For tough infestations, repeat the process or combine with diluted vinegar for enhanced results. Always ensure walls are fully dry afterward to prevent regrowth.

Baking soda raises the pH of surfaces, creating an inhospitable environment for mould spores. Its mild alkalinity disrupts mould cell walls while being safe for painted and plaster walls. Unlike chemical cleaners, it won’t damage paint, grout, or wallpaper—making it a versatile choice for kitchens, bathrooms, and basements where moisture fosters mould growth.

After cleaning, improve ventilation in affected areas and address underlying moisture issues—leaks, condensation, or poor airflow fuel mould. Regular maintenance with periodic baking soda sprays can help keep walls mould-free. Pairing this method with natural dehumidifiers enhances results and supports a healthier indoor environment.
