Waking up to condensation creeping across bedroom and living room windows is a common occurrence. While it may seem harmless, it can quickly lead to damp, mould and even damage to window frames and windowsills if left unchecked. While a dehumidifier can work to prevent excess moisture, it can be costly.
A window expert has recommended a budget-friendly trick to try instead, and it costs just 50p. Allan Reid, double-glazed windows expert from Art Windows and Doors, said: “It sounds almost too simple to work, but it really does.
“A small bowl of salt acts as a natural dehumidifier, drawing moisture from the air before it can settle on your windows.
“It’s an old trick, but one we still recommend to customers who want a quick, no-cost fix.”
Other moisture-absorbing materials, such as silica gel, can also work, but salt is more commonly found in cupboards.
Simply place a small bowl or silica gel on your windowsill before bed in rooms prone to condensation.
Wipe down any moisture first, so it doesn’t just sit there overnight. Open windows briefly in the morning to release any trapped damp air and freshen the room.
The expert said: “Regularly replace the salt or silica gel once it becomes clumpy, as that’s a sign it’s absorbed as much moisture as it can.
“Keep trickle vents open where possible to maintain airflow even in cold weather. Make sure to also inspect and reseal older windows if needed, as damaged seals are a common hidden cause of persistent condensation.”
Consider moving furniture away from exterior walls to improve airflow, too, which will help to reduce moisture build-up.
Allan added: “All it takes is a few minutes each evening and small adjustments around your home. Using simple, low-cost methods like this can prevent winter condensation from causing long-term damage, keeping your home drier and healthier as temperatures drop.”
