How to Stop Condensation in Cars

One issue that all drivers have in common, regardless of their level of experience, is struggling with condensation on car windows. Plus, being this time of the year, where temperatures are dropping rapidly, that means that more time is spent in the morning wiping away that mist which is never enjoyable. However, it’s important to remember to make sure to clear all your windows as fog can make it difficult for you to see, as well as impairing your driving.

What causes condensation?

When the temperature inside your car is lower than outside, this is when condensation will occur, as when the warm air inside of your car meets the cold windscreen, this transforms vapour into water.

However, it’s not just the colder temperatures overnight that can cause condensation, this will also be caused by yours/your passengers’ breath, a blocked pollen filter (whose purpose is to clean the air entering the car), wet clothes left inside the car (as the moisture evaporates – this also applies to wet seats or car mats) and hot drinks, which will eventually evaporate over time causing moisture.

How to get rid of condensation?

There are several ways to get rid of condensation on your car windows, this includes:

Turning on your heater: To get the best results, start your heater off cold, then gradually increase the temperature so that the air starts to dry out. Also, make sure that the heated air is directed towards the windows as well as your windscreen.

Turn on your A/C: When you turn on the air conditioning, all the air in your car passes through an evaporator which condenses the air and then releases it outside of your car. It's important to remember though that the moisture in the air that causes condensation in your car won't completely go away unless you’re A/C filters are frequently recirculated from “internal air” to “fresh air”.

Purchase a moisture absorbent or car dehumidifier: Absorbers are full of silicone balls or silica gel and whilst sitting on top of your dashboard they’ll be able to soak up moisture from the air inside your car. Just remember to wash it and dry it out when it feels heavy or damp. Our Perrys Part store has got some in stock, have a look here.

Open your doors and windows: It might not be easy to do so every time as when it’s winter the weather is unpredictable. However, if it’s a nice and sunny day, roll down your car windows and keep your doors ajar if you can. This will help airing out your car, letting the humid air escape, as well as allowing fresh air to circulate.

We hope this article had helped you get a better understanding with regards to what to do when you struggle with condensation. However, should you have any further queries, please don’t hesitate to contact us.
