As the colder months set in across Britain, a familiar and unwelcome guest often appears around window frames: mould. Many homeowners instinctively reach for a bottle of bleach to tackle the unsightly black spots, but experts are now warning that this common method is not only ineffective but could make the problem worse.
The Problem with Using Bleach on Mould
The primary cause of mould around windows is condensation, which is almost unavoidable during Britain's characteristically wet and chilly months like December. While numerous households opt for bleach, this approach is flawed. Using bleach might cause the mould to migrate to areas that were previously untouched, effectively spreading the problem rather than solving it.
Jade Oliver, a showroom stylist at Express Bi-Folding Doors, cautions against this practice. She states unequivocally: "Bleach doesn't work and won't make mould go away."
The Superior Kitchen Cupboard Solution
So, what is the effective alternative? The expert recommendation is a simple item found in most kitchens: white vinegar. Jade Oliver recommends that white vinegar left for around an hour, followed by wiping with a cloth soaked in warm, soapy water, will clear it.
Common white vinegar with five per cent acidity performs optimally when used undiluted, so there is no need to mix it with water. However, since it is a gentle acid, you should avoid using it on sensitive surfaces like aluminium, cast iron, waxed timber, or natural stone to prevent damage or marking.
How to Safely and Effectively Remove Mould
For safe application, always wear protective non-porous gloves, goggles or safety spectacles, and a mask covering your mouth and nose.
Follow this simple step-by-step guide for best results:
- Fill an empty spray bottle with sufficient undiluted white vinegar to treat the mouldy area.
- Spray the mould thoroughly, ensuring it is completely drenched, and leave the vinegar to work for at least one hour. Resist the temptation to scrub or wash it away immediately, as the mould needs time to absorb the vinegar.
- After an hour, take a brush or scouring pad and scrub the problem area vigorously.
- Rinse the area thoroughly with clean, warm water.
- For a final, preventative touch, give the area another spray of vinegar. This will kill any lingering mould spores and help stop them from returning.
Do not worry about the strong smell of vinegar; it will naturally disappear within a few hours.
Pro-Tips for Cleaning Windows Themselves
For windows covered in layers of dirt, do not rush to grab a bucket of soapy water, as this can make dust stick to the glass more stubbornly. Jade offers a better solution: "Use a duster to loosen any dust particles first and then try gently vacuuming with the bristle attachment to avoid scratching the surface."
For those hard-to-reach areas like corners and rims, she advises using a feather duster to manipulate and remove the grime effectively. By tackling both the mould and the general grime, you can ensure your windows are spotless and healthier throughout the winter season.
