Mould and mildew on walls can be unsightly and harmful to your health. These fungi thrive in damp, humid environments and, if left untreated, can cause severe damage to your home. If you’re wondering how to remove mould on walls without causing discolouration, you’re in the right place. In this guide, we’ll take you through several steps to help you eliminate mould and mildew effectively while ensuring your walls remain spotless.
Identify the Root Cause of Mould
Before you start the cleaning process, it’s essential to identify what’s causing the mould and mildew. The most common cause is excess moisture, often from poor ventilation or leaks in walls or ceilings. Fixing the root cause will prevent mould from returning. Whether it’s a leaking pipe or condensation from poor airflow, addressing this first ensures you tackle the problem at its source. Doing so reduces the risk of future mould growth, which can help preserve the condition of your walls.
Choose the Right Cleaning Solution
When figuring out how to remove mould from walls, choosing a solution that’s effective against mould but gentle on your walls is essential. While bleach is ordinary, it can sometimes damage the paint or leave discolouration behind. Instead, opt for a non-abrasive cleaner. White vinegar is an excellent natural option as it kills mould without causing damage. Alternatively, hydrogen peroxide can be as effective, particularly for more challenging mould patches. Mix a water solution and your chosen cleaner, ensuring the concentration is not too strong to avoid affecting the wall’s appearance.
Protect Yourself and Your Space
Before you begin cleaning, wear protective gear such as gloves and a mask to avoid inhaling harmful spores. Mould can release toxins that can irritate the skin and respiratory system. You’ll also want to protect your space by covering any furniture or nearby areas with plastic sheets to avoid spreading spores during cleaning. Keeping the room well-ventilated while cleaning will also help prevent fumes from building up, especially if using chemical-based solutions.
Scrub Gently to Avoid Wall Damage
Once you have your cleaning solution ready, it’s time to start scrubbing. Use a soft sponge or cloth to apply the solution to the affected area. Avoid using abrasive brushes or scrubbers, as these can damage the wall surface and potentially cause discolouration of the wall. When removing mildew on walls, it’s essential to be gentle but thorough. Start at the edges of the affected area and work your way in, applying light pressure to lift the mould without damaging the paint or wallpaper underneath. If you encounter stubborn spots, allow the solution to sit for a few minutes before wiping it away.
Rinse and Dry the Area Thoroughly
After scrubbing the walls, you’ll need to rinse the area to remove any residue from the cleaning solution. Use a clean, damp cloth to wipe down the walls, ensuring no cleaner is left behind, as it could cause discolouration. Once rinsed, dry the area thoroughly with a dry cloth or towel. Moisture is the enemy when dealing with mould, so ensure the wall is arid to prevent further growth. Opening windows or using a dehumidifier can also help speed up drying.
Use a Mould Inhibitor
Consider applying a mould inhibitor after cleaning to protect your walls from future mould growth. These products are specifically designed to prevent mould spores from settling and growing. You can purchase a commercial mould inhibitor or make a DIY version by mixing water with a few drops of tea tree oil, which has natural antifungal properties. Applying this solution will help ensure that your walls remain mould-free for longer, and you won’t have to worry about reappearing patches.
Address Stains without Discolouring the Wall
If you’ve followed all the previous steps but still notice stains from the mould, you’ll want to address them carefully. Stains can sometimes appear even after the mould is gone. If the wall surface allows, gently scrub the stained area using a mild solution of baking soda and water. This can help lift any remaining discolouration without damaging the paint or wallpaper. In some cases, touching up the wall with a small amount of matching paint may be necessary if the stains persist. However, always test any cleaner or paint in an inconspicuous area first to ensure it won’t cause further discolouration.
Keep the Area Well Ventilated
Finally, prevention is critical. To prevent mould from reappearing, keep the area well-ventilated. Mould thrives in damp environments, so ensuring proper airflow can significantly reduce the chances of it returning. Use exhaust fans in bathrooms and kitchens, and consider opening windows regularly to allow fresh air to circulate. If humidity is an issue in your home, using a dehumidifier can help keep moisture levels in check, reducing the likelihood of mould growth.
Conclusion
Removing mould and mildew from walls requires careful attention to prevent damage and avoid discolouration. By following these steps, you can effectively eliminate mould without compromising the appearance of your walls. Ensuring proper ventilation and addressing moisture issues will also help keep mould from returning.
