Understanding the Musty Odour
That distinct earthy or damp towel smell is not just in your head. It's caused by the rapid growth of mould and mildew, which thrive in the high-humidity environment of the monsoon. These fungi release microbial volatile organic compounds (MVOCs) into
the air as they grow, which our noses detect as a musty scent. With indoor humidity levels in some Indian cities reaching 80-90% during this season, mould spores, which are always present in the air, find plenty of damp surfaces like walls, furniture, and fabrics to settle on and multiply. This process can start in as little as 24 to 48 hours in a damp environment.
Boost Ventilation Whenever Possible
The simplest and most crucial step is to improve air circulation. Trapped, stagnant air is a primary cause of dampness. Make it a habit to open windows and doors for at least 15-20 minutes daily, especially during drier parts of the day, to allow fresh air to circulate and push out the damp air. Creating cross-ventilation by opening windows on opposite sides of the home is particularly effective. Use exhaust fans in kitchens and bathrooms not just during, but for about 10 minutes after cooking or showering to expel moisture at its source. Keeping a small gap between furniture and walls will also improve airflow and prevent mould from growing in hidden corners.
Use Natural Moisture Absorbers
For enclosed spaces like wardrobes, cabinets, and small rooms where ventilation is limited, natural desiccants can be very effective. Rock salt and coarse sea salt are highly hygroscopic, meaning they naturally draw moisture from the air. You can place bowls of salt in damp corners or create small pouches (potlis) to hang in your closets. Activated charcoal is another excellent option that not only absorbs moisture but also neutralises odours. Place charcoal briquettes or bags in shoe racks, bathrooms, and wardrobes. Open boxes of baking soda can also serve a similar purpose in smaller areas like drawers.
Protect Your Wardrobe and Linens
Clothes and fabrics are especially prone to developing that musty monsoon smell. Ensure clothes are completely dry before storing them. If drying laundry indoors is unavoidable, use a fan to speed up the process and open a nearby window if possible. To protect stored items, place natural repellents and fresheners inside your closets. Dried neem leaves have antifungal properties and can help prevent mildew. Camphor is also a traditional and effective remedy for getting rid of fungal growth and its associated smell. Silica gel packets, often found in new shoe boxes or bags, can be saved and placed in drawers and storage containers to keep them dry.
Clean and Neutralise Odours at the Source
Simply masking the smell with air fresheners is a temporary fix. To eliminate the odour, you must tackle the source. A solution of equal parts white vinegar and water can be sprayed on walls or surfaces where you suspect mould growth. Vinegar is a natural deodorizer and helps to kill mould spores. For cleaning floors and other surfaces, you can use disinfectants. Check for any leaks in pipes, roofs, or around windows, as these are common sources of water intrusion that lead to persistent dampness. Wiping down wet surfaces, including condensation on windows, can also make a significant difference.
Consider a Dehumidifier for Problem Areas
If you live in a particularly humid area or have rooms that are chronically damp, such as basements or ground-floor apartments, an electric dehumidifier might be a worthwhile investment. These appliances actively pull excess moisture from the air, collecting it as water, which inhibits the growth of mould and mildew. Many modern air conditioners also come with a 'Dry Mode' that functions similarly, reducing humidity without over-cooling the room, making it a great feature to use during the monsoon.
