Mould on windows 'won’t go away’ with bleach - but kitchen staple ‘clears it’

Mould around windows is a familiar sight and increasingly so during the damp, chilly conditions typical of December. It's often caused by condensation, and controlling this can help prevent mould growth.

While some might reach for bleach to tackle window mould, Jade Oliver, a showroom stylist at Express Bi-Folding Doors, warned against it, advising: "Bleach doesn't work and won't make mould go away, however, white vinegar left for around an hour with a cloth soaked in warm, soapy water will clear it."

White vinegar is effective when used straight from the bottle, and for most effectiveness, it should be used undiluted. Nevertheless, due to its acidity, refrain from using it on aluminium, cast iron, waxed wood, or natural stone to avoid damage.

When applying vinegar, it's also advisable to wear protective gear like non-absorbent gloves, safety goggles, and a face mask. Simply fill a spray bottle with sufficient undiluted white vinegar, drench the mouldy area, and leave it for a minimum of one hour without scrubbing or rinsing to let the mould fully absorb the vinegar.

Firstly, tackle the problem area with a brush or scouring pad, giving it a thorough scrub. After a good clean, rinse the space with warm water, reports the Express.

To ensure all mould spores are eradicated and prevent their return, spray the area with vinegar after the initial wash and rinse. The strong smell of vinegar will naturally dissipate in a few hours, so there's no need to worry about any lingering odour.

For windows caked in dirt, resist the urge to use soapy water as it can make dust stick to the glass even more. Instead, Jade recommends: "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 spots, Jade offers a pro-tip: "Finally, to get into any tougher nooks and crannies such as the corners and rims, work in a feather duster to manipulate the grime."
