Winter in Canterbury brings cold temperatures, condensation, and unfortunately for many homeowners and renters — mould. If you've noticed dark patches creeping up on your walls, window frames, or bathroom tiles, you're not alone. Mould is one of the most common household problems during the colder months, and left untreated, it can affect both your home and your health.
The good news? For small patches, there's a simple, affordable remedy sitting in most kitchen cupboards — white vinegar.
Why White Vinegar Works
White vinegar is a mild acid, which makes it surprisingly effective at killing mould on non-porous surfaces. Unlike many commercial mould sprays, it's non-toxic, eco-friendly, and safe to use around children and pets — which aligns perfectly with our approach to cleaning at Clean O'Clock.
How to Use It
The method is straightforward:
- Pour undiluted white vinegar into a spray bottle
- Apply generously to the affected area
- Leave it to sit for at least an hour — don't rinse it off straight away
- Wipe clean with a damp cloth and dry the surface thoroughly
- Repeat weekly for ongoing prevention in high-moisture areas
For bathroom tiles, window sills, and walls, this method works well on surface-level mould. The key is catching it early before it has a chance to spread or penetrate deeper into the surface.
Prevention is Better Than the Cure
While white vinegar is a great short-term fix, the best approach to mould is preventing it from taking hold in the first place. A few simple habits can make a big difference during winter:
- Open windows where possible to improve airflow, even for a few minutes a day
- Use an extractor fan during and after showers
- Wipe down condensation from windows and sills in the morning
- Keep furniture slightly away from exterior walls to allow air circulation
- Consider a dehumidifier in particularly damp rooms
When to Call in the Professionals
If mould has spread across a large area, returned repeatedly despite treatment, or appears to be behind walls or under flooring, it's time to seek professional advice. Extensive mould can be a sign of a deeper moisture problem in the property and may require more than a DIY fix.
For surface-level mould as part of a broader clean, our Service Specialists can help tackle affected areas as part of a Premium Clean or End of Tenancy service. We use eco-friendly, reputable products to leave your home fresh, clean, and healthy.
