How to stop condensation in your car

How to stop condensation in your car

It’s first thing in the morning, it’s cold and you’re running late for work – but the car’s completely misted up inside - sound familiar? We know moisture in your car can be frustrating, especially during the cold and wet months, so we’ve pulled together what you need to know so you can prevent condensation.

What causes condensation in cars?

Condensation forms when warm air containing moisture comes into contact with a cold surface. Below are some examples of what causes moisture to build-up in your car:

  • The conflict of temperatures and moisture levels on the inside and outside of your car – a common occurrence during the cold and wet weather.
  • Damp items left in the car, such as an umbrella or a coat.
  • Hot and steamy food or drinks, and rubbish left in the car.
  • Leaks in the doors, windows or the sunroof (if you have one).
  • Damp carpets or car mats.
  • Coolant leaking from the heater matrix into your car.
  • Limited circulation of fresh air.

How to get rid of car condensation

Once you’ve uncovered the cause of your moisture problem, make sure you remove any damp items from your car and leave them to dry elsewhere. If you’ve identified an issue with damaged seals or a leaking heater, it’s worth taking your car to the garage before it becomes a bigger problem.

If you regularly find yourself with a misty view from your car, allow yourself a few extra minutes in the morning and follow this guide before taking off.

  • Turn on the heaters that blow directly onto your windscreen.
  • Turn on the air-conditioning, as this helps to remove the moisture in the air.
  • Open the car windows a couple of inches, to allow the build-up of moisture to escape from the car.

How to prevent car condensation

Now that you’re familiar with the causes and how to remove condensation, there are several ways to prevent your car from turning into a moisture trap.

  • Clean your car regularly.Dirt provides additional surface area for moisture to settle on, so clean your windows regularly with a smear-free spray.
  • Ventilate your car.When it’s safe and it’s not raining, allow your car a breather by leaving the windows open for a couple of hours.
  • Avoid leaving damp items in your car, not forgetting rubbish as well - as they can both contribute to high levels of moisture in your car.
  • Check for signs of damp.Your car may have broken seals around the sunroof, doors and windows, or the heater matrix could be leaking - so it’s worth keeping an eye out for damp. If you think there’s an issue, take your car to the local garage to be assessed.
