As Storm Goretti batters the UK with heavy snow and winds up to 99mph, thousands of households are waking up to fogged-up windows and damp windowsills. Condensation not only reduces visibility in cars but also promotes mould growth and dampness at home, leading to potential health and structural issues.
An unusual but low-cost solution involves using a raw potato. The starch in the potato creates a thin, invisible coating on glass that temporarily repels moisture, preventing water droplets from forming. Simply cut a potato in half, rub the cut side across the interior of the window or windscreen, then buff lightly with a dry cloth.
Product manager Katie Mansfield from California Shutters explains: 'Condensation occurs when warm, moist air hits cold surfaces like windows. The starch in a potato creates a barrier that reduces moisture build-up. It's a quick, low-cost trick for colder months, though not a long-term fix.'
Shoppers can buy a single baking potato for as little as 24p at Aldi or Tesco. Mansfield also recommends opening windows slightly during the day and using dehumidifiers to control indoor moisture levels.
