Expert's 65p trick to banish harmful window condensation during autumn

A budget-friendly essential could be the secret to keeping your windowsdry this autumn.

As the autumn chill sets in, households are being advised to use an unexpected weapon against one of the season's biggest annoyances - condensation. Experts suggest that simply using table salt, which can be bought for as little as 65p at Morrisons or Aldi for those who don't already have some at home, will do the job.

Condensation becomes more prevalent as homes warm up and outdoor temperatures fall, causing warm indoor air to hit cold glass. Over time, this moisture build-up can lead to damp spots, mould and even potential health hazards.

A 2024 report by the Ministry of Housing, Communities and Local Government revealed that 6.5 million households, around 23% of all UK homes, could be affected by damp and mould in the upcoming years, underlining just how widespread the issue is.

Not only does it pose health risks, but it is also a costly problem to fix. According to MyJobQuote, minor condensation repairs for double glazed windows could range between £300 and £500.

However, salt, a natural moisture absorber, can help avoid any potential embarrassment by drawing excess moisture from the air, meaning fewer droplets form when warm indoor air meets cold window surfaces. The experts say this small but effective step can make a big difference in keeping homes drier throughout the colder months.

A spokesperson for Lottomart said: "Regular condensation build-up isn't just unsightly - it can become a breeding ground for mould, which poses risks to household health."

They continued: "The method is really easy to follow. All you need to do is fill a small bowl or jar with table salt and place it on your windowsill. Once the salt clumps together, that's your sign to replace it with a fresh batch to keep it working effectively."
