Stop Overnight Condensation with a Simple 50p Household Trick

As the cooler months arrive, many of us notice the frustrating build-up of condensation on our windows. This common issue occurs when warm, moist air meets a cold surface, causing water vapor to turn into droplets, fogging up your glass. While commercial solutions can be costly, there’s a surprisingly simple and affordable trick that can help keep your windows clear overnight—using just 50p worth of a household staple.

Allan Reid, a double-glazing expert from Art Windows and Doors, reveals that placing a small bowl of table salt near your windows can effectively reduce moisture in the air. This low-cost, natural dehumidifier absorbs excess humidity before it settles as condensation on your glass.

“It may seem almost too simple, but a bowl of salt really draws moisture from the air and keeps your windows dry,” Allan says. “It’s an old household trick that still works wonders and is perfect for a quick, no-fuss fix.”

Here’s how to use this handy method:

Fill a small bowl or container with table salt.
Place it on your windowsill or close to the window surface where condensation tends to form.
Replace the salt regularly, especially when it becomes damp or clumpy, indicating it has absorbed moisture to full capacity.

For longer-term control of condensation, Allan also recommends:

Keeping trickle vents open to improve air circulation.
Checking and resealing windows to address leaks.
Moving furniture slightly away from cold external walls to enhance airflow.

Additionally, washing up liquid offers another easy preventive method. Applying a tiny drop rubbed across the window glass with a dry cloth can stop condensation from forming, leaving windows clear come morning.

With just a few simple steps and everyday items, you can protect your home against the dampness and damage caused by winter condensation, creating a drier, healthier living environment.
