Is it True that Vinegar Stops Condensation on Windows?

As the winter months creep upon us, one of the most common problems homeowners face is condensation on their windows. This issue not only obstructs your view but can also lead to mould growth, causing potential health problems and damage to your property. You may have heard about the age-old remedy of using vinegar to stop condensation. But does it really work? Let’s find out.

What is Condensation?

Before we delve into the solution, it’s essential to understand the problem. Condensation is the process where warm, moist air comes into contact with a cold surface and turns into water droplets. In homes, this often occurs on windows, particularly during the cooler months when there’s a significant temperature difference between the inside and outside of your property.

Condensation isn’t just an aesthetic issue. Over time, it can lead to dampness and mould, which can damage your window frames and walls. Plus, mould spores can aggravate allergies and asthma, posing a health risk.

The Vinegar Solution: Does It Work?

Vinegar is a common household staple with a world of uses, from cleaning to cooking. Its acidic nature makes it excellent for breaking down grime and mineral deposits, which is why it’s often touted as a solution for window condensation.

The theory is simple: by applying a solution of vinegar and water to your windows, you can eliminate the surface conditions that allow condensation to form. The vinegar supposedly creates a barrier that prevents moisture from settling, thus reducing condensation.

However, while vinegar can indeed clean your windows and remove surface grime, it does not provide a long-term solution to condensation. The vinegar solution needs to be reapplied frequently, and it does not address the fundamental issue of excess moisture in your home.

The Real Solution: Effective Ventilation and Insulation

At Lancashire Double Glazing, we believe in providing long-lasting solutions. While vinegar may provide temporary relief, it doesn’t tackle the root cause of condensation. For that, we need to look at improving ventilation and insulation in your home. New windows from Lancashire Double Glazing can help reduce condensation.


Good ventilation is key to managing moisture levels in your home. By allowing fresh air to circulate, you can reduce the amount of warm, moist air that causes condensation. Regularly opening windows, using extractor fans in kitchens and bathrooms, and installing trickle vents can all help to improve ventilation.


Meanwhile, insulation keeps your home’s internal temperature stable, making it harder for condensation to form on windows. Double glazing is an especially effective form of insulation. By trapping a layer of air between two panes of glass, double glazing creates a barrier that prevents heat transfer, reducing the chance of condensation.
