Why Mould Loves the Monsoon
Mould is a type of fungus, and its spores are present almost everywhere, indoors and out. These spores remain dormant until they land on a spot that has the two things they need to grow: moisture and organic material to feed on. The Indian monsoon provides
the perfect environment. With humidity levels often soaring above 80-90%, surfaces rarely get a chance to dry out completely. Walls, wooden furniture, clothes, and even the grout between tiles can become breeding grounds. Mould doesn't just look and smell bad; exposure can cause allergic reactions like sneezing, a runny nose, itchy eyes, and skin irritation. For individuals with asthma or weakened immune systems, the effects can be more severe.
First, Play Defence: Control Moisture
The most effective way to fight mould is to control the moisture in your home. The key is to keep indoor humidity levels below 60%, ideally between 35% and 50%. Start by identifying and fixing any leaks in your roof, walls, or plumbing without delay. Use exhaust fans in kitchens and bathrooms to expel steam from cooking and bathing. If you don't have an exhaust fan, opening a window for a while after these activities helps. Avoid drying clothes indoors if possible, as this releases a large amount of moisture into the air. If you must, ensure the room is well-ventilated. In especially damp areas, consider using a dehumidifier or placing moisture-absorbing products like silica gel sachets in cupboards and closets.
Let Your Home Breathe
Good ventilation is crucial for preventing moisture from settling on surfaces. Even during the rains, try to open windows and doors for a while on dry or less humid days to allow for cross-ventilation. This helps to carry damp indoor air out and bring fresh air in. Pay attention to areas with poor airflow. Pulling large furniture, like cupboards and beds, a few inches away from the walls allows air to circulate behind them, preventing the hidden growth of mould. Regularly airing out textiles that are not washed frequently, like curtains and cushions, by shaking them out and hanging them in a breezy spot can also make a big difference.
Found Mould? Here’s How to Fight Back
For small areas of mould, you don't necessarily need harsh chemicals. White vinegar is a highly effective and safe cleaner. Its acetic acid can kill a majority of mould species. Simply put undiluted white vinegar into a spray bottle, spray it directly onto the mouldy surface, and let it sit for at least an hour. Then, scrub the area with a brush. For a more powerful clean, you can create a paste with baking soda and water. Apply the paste after the vinegar treatment, scrub again, and then wipe the area clean with a damp cloth. Always wear gloves and a mask to avoid inhaling spores during cleanup. After cleaning, ensure the surface is dried completely.
Winning the War: Long-Term Strategies
For long-term prevention, a few strategic choices can fortify your home against mould. When it's time to repaint, consider using mould-resistant or waterproof paints, especially on exterior walls and in high-moisture areas like bathrooms and kitchens. Ensure water from your property drains away from the house's foundation. When storing items like clothes or books, use breathable cotton bags instead of sealed plastic containers, which can trap moisture. Finally, be vigilant. Regularly inspect common problem areas like the corners of rooms, behind furniture, inside wardrobes, and around window sills. Catching a small patch of mould early is much easier than dealing with a large infestation later.
