A clever life hack shows how using a cheap ingredient can help prevent condensation on car windows – so here’s everything you need to know about the simple method
As we approach that time of year when car windows become a magnet for foggy condensation, a simple hack could be the solution to your woes.
A TikTok user known as ND_home has shared a clever trick that’s quickly gone viral, with many hailing it as a stroke of genius. According to the content creator, all you need to clear your windows of moisture is a humble item from your kitchen cupboard.
The trick involves taking half a potato and rubbing it over the affected area. Once dry, add a bit of water to the window and wipe it clean. It’s as straightforward as that – and your windows will be gleaming in no time!
The hack has proven incredibly popular, with the video amassing over 30,000 views so far. One viewer commented: “So helpful. Great car hack.” Another wrote: “Really useful hack.” Meanwhile, a third chimed in with: “Genius car hack.”
Why does condensation form on car windows?
When it’s cold outside and warm (and humid) inside the car, the inside surface of the windows can be cooler than the air inside.
Warm, moist air inside the car touches the cold glass, cools down, and can’t hold as much moisture. The excess moisture turns into water droplets – and this is condensation.
Other factors can also contribute to foggy windows. Activities like breathing, wet clothes, or bringing snow into the car have an impact.
The more humid the air inside, the more likely condensation will form when the windows are cold.
How does the hack work
Experts explain that the trick works due to the properties of a clean potato, so ensure to give it a wash if it’s a bit grubby.
If you have an old spud that’s started to sprout, this is the perfect opportunity to put it to use. Use the flat side to rub along the window, making sure to cover the entire area from side to side.
This method should not only clean the window but also create a layer that prevents condensation from forming. If you notice any starchy streaks beginning to appear, simply wipe them off promptly.
If you’re planning to apply this treatment to all your vehicles’ windows, you might need to utilise both halves of the potato to complete the task. Then, just let it dry thoroughly before touching.
Once the potato juice has dried, the windows should remain free of fog. This is due to the starch in the potato forming a barrier between the glass and the air. Genius!
