When it comes to household fungi, mould and mildew are often used interchangeably. However, these two are distinct in appearance, growth patterns, and potential health risks. Understanding their differences is crucial for effective treatment and prevention.
What is Mildew?
Mildew is a type of surface fungus that thrives in damp, warm environments. It is often found in bathrooms, kitchens, and basements where moisture levels are high.
Characteristics of Mildew:
- Appearance: Powdery or fluffy texture, typically white, grey, or yellow.
- Growth Pattern: Forms in flat patches on surfaces like walls, tiles, fabrics, and paper.
- Smell: Musty but less pungent than mould.
- Health Effects: Can cause mild allergic reactions, such as coughing, sneezing, or skin irritation.
How to Treat Mildew:
- Vinegar Solution: Mix equal parts white vinegar and water in a spray bottle. Apply to the affected area and scrub gently.
- Hydrogen Peroxide: A 3% hydrogen peroxide solution can effectively remove mildew from porous surfaces.
- Baking Soda: Sprinkle baking soda on affected areas, leave for 10 minutes, and wipe clean.
- Prevention: Improve ventilation, use a dehumidifier, and wipe down damp surfaces regularly.
What is Mould?
Mould is a more aggressive type of fungus that penetrates deeper into surfaces, making it harder to remove. It can cause significant structural damage and health issues if left untreated.
Characteristics of Mould:
- Appearance: Fuzzy or slimy texture, often black, green, blue, or red.
- Growth Pattern: Develops in large, irregular patches and can penetrate walls, ceilings, and fabrics.
- Smell: Strong, musty odour.
- Health Effects: Can trigger serious allergic reactions, respiratory issues, and exacerbate conditions like asthma.
How to Treat Mould:
- Professional Remediation: If mould covers an area larger than 1m², professional removal is recommended.
- Protective Gear: Always wear gloves, a mask, and eye protection when dealing with mould.
- Fix Moisture Issues: Identify and address leaks, poor ventilation, or condensation problems to prevent regrowth.
Preventing Mould and Mildew Growth
- Maintain Ventilation: Use exhaust fans in bathrooms and kitchens.
- Control Humidity: Keep indoor humidity levels below 50%.
- Fix Leaks Promptly: Address any water damage or leaks immediately.
- Regular Cleaning: Wipe down damp areas, especially in high-moisture rooms.
- Use Mould-Resistant Products: Opt for mould-resistant paint and building materials in prone areas.
