How to Clean and Prevent Mould in HDB: Protect Your Family from Harm

  • 3 min reading time

Mould is a silent invader that can gradually take over your home if left unchecked, especially in areas with high humidity, like Singapore's HDB flats. Mould infestation is not just an aesthetic issue – it can also pose serious health risks to family members, making it critical to address promptly.

The Harm of Mould

Before diving into how to clean and prevent mould, it's important to understand why it's a threat. Moulds are a type of fungi that release tiny spores into the air. These spores, when inhaled, can cause health problems, particularly for those with allergies or asthma. Symptoms can range from mild, such as sneezing, coughing, and watery eyes, to severe, including difficulty breathing and chest tightness.

Moreover, prolonged exposure to mould can lead to the development of chronic respiratory illnesses and even neurological problems like memory loss and mood changes. Children, the elderly, and individuals with weakened immune systems are especially vulnerable to the harmful effects of mould.

Cleaning Mould in HDB Flats

Cleaning mould effectively requires a few steps:

  1. Identify the Mould: Mould often manifests as a black or green patch on walls, ceilings, or furniture. It may also produce a musty smell.

  2. Wear Protective Gear: Before starting the cleaning process, ensure you wear protective clothing like gloves, masks, and goggles to avoid direct exposure to mould spores.

  3. Prepare a Cleaning Solution: A simple yet effective solution can be made using household bleach and water. Mix one part bleach to three parts water.

  4. Scrub the Mould: Use a stiff-bristle brush to scrub the mould off the surfaces. Always scrub in a well-ventilated area and avoid touching your face during the process.

  5. Rinse and Dry: After scrubbing, rinse the surface with clean water. It's essential to thoroughly dry the area afterwards, as mould thrives in damp conditions.

  6. Dispose of Cleaning Materials: Safely dispose of any rags or brushes used to clean the mould to avoid spreading the spores.

Preventing Mould in HDB Flats

Prevention is always better than cure. Here's how you can prevent mould in your HDB flat:

  1. Improve Ventilation: Ensure your home is well-ventilated, especially in areas like the kitchen and bathroom. Consider installing exhaust fans or keeping windows open to help dissipate moisture.

  2. Control Humidity: Try to maintain indoor humidity below 60%. Dehumidifiers can help in achieving this.

  3. Regular Cleaning: Regularly clean areas that are prone to mould, such as bathrooms, kitchens, and any damp areas around windows or air conditioning units.

  4. Promptly Repair Leaks: Any leaks in the plumbing or roof can contribute to dampness and promote mould growth. Fix them as soon as possible.

  5. Use Mould-Resistant Products: Consider using mould-resistant paint, tiles, or other materials in areas prone to dampness.

By implementing these cleaning and preventive measures, you can keep your HDB flat mould-free, providing a healthier living environment for your family. However, if the mould infestation is severe or keeps returning, it may be worth consulting a professional for more effective solutions. Remember, a mould-free home is not just a cleaner home, but also a safer one for your loved ones.
