Why Mould Matters for Your Health
Mould thrives in moist, warm environments and spreads by releasing tiny spores into the air. When inhaled, these spores can irritate the respiratory system, especially in people with asthma, allergies, or weakened immune systems. Common symptoms of mould exposure include:
- Sneezing, coughing, and nasal congestion
- Itchy eyes, skin rashes
- Wheezing or asthma attacks
- Fatigue and headaches
In severe cases or prolonged exposure, mould can even contribute to chronic respiratory conditions or fungal infections.
Top Spots Mould Likes to Hide
- Bathrooms (especially under sinks and around tiles)
- Kitchens (under appliances or around leaky pipes)
- Basements and crawl spaces
- Window sills and air conditioning units
- Behind wallpaper or drywall
How to Keep Mould Out of Your Home
1. Control Humidity
Keep indoor humidity levels below 50%. Use a dehumidifier in damp areas and ensure good ventilation in bathrooms and kitchens.
2. Fix Leaks Quickly
Whether it’s a dripping tap or a roof leak, moisture is mould’s best friend. Repair leaks immediately to prevent mould-friendly conditions.
3. Improve Ventilation
Use exhaust fans in bathrooms, kitchens, and laundry rooms. Open windows regularly to promote airflow.
4. Clean and Dry Promptly
Clean spills and wet areas within 24–48 hours. Don’t leave damp towels, clothes, or rugs sitting around.
5. Use Mould-Resistant Products
If renovating, opt for mould-resistant drywall and paints, especially in high-moisture areas.
6. Regular Maintenance
Inspect your home seasonally for signs of mould—especially after heavy rains or snowmelt.
7. Clean Smart
Use white vinegar or a commercial mould cleaner to scrub away visible mould. Avoid bleach on porous surfaces, as it may not fully kill the mould.
Does vinegar kill mould?
Yes, vinegar does kill many types of mould—especially surface mould on non-porous or lightly porous materials like tiles, glass, and walls.
Why vinegar works:
White distilled vinegar contains acetic acid, which has antifungal and antibacterial properties. It can kill about 80% of mould species, including some black moulds (like Cladosporium), but it’s not effective against all mould types, especially if the infestation is deep or behind walls.
How to use vinegar to kill mould:
Use undiluted white vinegar (5–6% acetic acid).
Pour it into a spray bottle—no need to dilute it.
Spray directly onto the mouldy surface.
Let it sit for at least 1 hour.
Scrub with a brush or sponge, then wipe clean with warm water.
Let the area dry completely. You can re-spray lightly and leave it to air dry for added protection.
When vinegar might not be enough:
If the mould is on porous materials (like drywall, ceiling tiles, or insulation), vinegar might not penetrate deep enough.
In cases of large infestations or toxic mould (e.g., Stachybotrys chartarum), professional removal is recommended.
For a stronger mould-fighting solution, you can combine vinegar and baking soda (but not mixed directly—they foam). Spray vinegar, let sit, scrub, then sprinkle baking soda for added abrasion and deodorising.
When to Call a Professional
If you spot extensive mould (more than a square meter), notice a persistent musty odour, or experience health symptoms you can’t explain, it’s best to bring in a certified mould remediation expert.
