How to Clean Mould from Windows: Safe & Effective Tips

by | Oct 28, 2024

Mould around windows can cause unsightly stains, damage your home, and even pose health risks if left untreated. Windowsills, frames, and seals are often ideal spots for mould to thrive due to condensation and moisture build-up. This guide will walk you through safe, effective methods to clean mould from windows, as well as tips to prevent future mould growth.

The Dangers of Mould on Windows

Before addressing the mould problem, it’s essential to understand the potential hazards. Mould can cause allergies, and respiratory issues, and, in severe cases, affect the nervous system. Black mould (Stachybotrys) can pose significant health risks, especially to those with pre-existing conditions. Therefore, acting quickly and cleaning the mould thoroughly is critical.

Why Does Mould Grow on Windows?

Mould thrives in damp, poorly ventilated spaces, and windows provide an ideal environment. Some common causes of mould growth on windows include:

  • Condensation: Moisture from temperature differences between indoor and outdoor air.
  • Poor insulation: Inadequate sealing leads to moisture build-up.
  • Water leaks: Small leaks around window frames encourage mould spores to grow.
  • Limited ventilation: Rooms with high humidity, such as bathrooms, kitchens, and basements, can trap moisture around windows.

Step-by-Step Guide: How to Clean Mould from Windows Safely

Follow these easy steps to remove mould and restore your windows to their clean and safe condition.

1. Gather Your Cleaning Supplies

You will need:

  • White vinegar
  • Baking soda
  • Spray bottle
  • Warm water
  • Dry cloth
  • Gloves
  • Face mask (to protect from mould spores)
  • Scrubbing brush

2. Ensure Proper Ventilation

Open nearby windows to allow airflow, minimizing the risk of inhaling mould spores during cleaning. If the room lacks windows, use a fan to improve ventilation.

3. Spray the Area with White Vinegar

Fill a spray bottle with white vinegar and apply it generously to the affected areas. Vinegar is a natural mould killer that eliminates 82% of mould species. Let it sit for 15 minutes to break down the mould.

4. Scrub the Surface with a Brush

After letting the vinegar work its magic, use a scrubbing brush to loosen the mould from the window sills and frames. For tougher mould spots, reapply the vinegar and scrub again.

5. Use Baking Soda for Extra Cleaning Power

Mix baking soda with warm water to create a paste. Apply it to the mouldy areas and scrub thoroughly. Baking soda helps eliminate residual mould and removes musty odors.

6. Wipe the Area with a Dry Cloth

Use a clean, dry cloth to remove the mould and any remaining moisture. It’s important to dry the area thoroughly to prevent further mould growth.

7. Rinse with Hot Water

Rinse the area with hot water and wipe it down with a fresh cloth to remove any residue from the vinegar or baking soda.

8. Dispose of Contaminated Materials

Immediately dispose of any used cleaning materials, such as gloves, brushes, or cloths, in a sealed bag to prevent mould spores from spreading.

How to Prevent Mould from Returning

Once you’ve removed the mould, taking preventive steps will help ensure it doesn’t come back.

1. Control Humidity and Moisture

  • Ventilate: Use exhaust fans in bathrooms and kitchens to reduce condensation.
  • Dehumidify: Install a dehumidifier in high-humidity rooms to maintain optimal moisture levels.
  • Open windows: Let fresh air in whenever possible to reduce indoor moisture.

2. Inspect Windows Regularly

Regularly check your windows for condensation, leaks, or gaps in seals. Address any issues promptly to prevent moisture accumulation.

3. Clean Your Windows Frequently

Routine cleaning prevents dust and dirt from trapping moisture, reducing the risk of mould growth. Consider professional window cleaning services for a thorough job.
