Removing Condensation and Mist from Car Windows
It’s a regular occurrence on vehicles of all types, and while it may not be the most noticeable blemish that could happen to your vehicle, it is still unsightly, annoying, and a hindrance to visibility. However, there are a number of ways that you can combat condensation in your vehicle with a few simple tricks, and this article will look into them in detail.
What is condensation?
Cold air is very dry, meaning there is little moisture in it. Warmer air is often more humid. When warm air comes into contact with a cold surface (such as a car windscreen), this water condenses on the surface in the form of water droplets. Though your car may feel freezing on the inside on a winter’s day, the air inside the cabin is still humid enough to cause condensation build-up on the cold windows.
What causes condensation?
Condensation occurs in situations where the temperature and moisture levels differ between the car and the outside air. In the sealed area of the car, the moisture comes into contact with the windscreen, which is cold, and condensation forms droplets which run down the inside of your windscreen, impairing vision.
Common causes of condensation
- Leaving damp items inside the car overnight
- Blocked pollen or air cabin filters
- Leaks in the heater matrix, rubber door seals or sunroof seal
How do I get rid of it?
Removing condensation from your windscreen requires a combination of preventative measures and a bit of elbow grease. When dirt particles attach themselves to the windscreen, it can exacerbate the condensation issue, so it is important that you clean the inside of your windscreen regularly. Using a car window cleaner and a microfibre cloth, scrub the glass until it is sparkling new.
Regular car washing is also important, as your vehicle contains numerous miniscule drains, which can get blocked up by debris, dust and dirt, creating damp if not cleaned out regularly.
If you notice that your windscreen is covered in condensation when you get in, it is important that you do not drive until your view is clear. Turn on the heating and direct it at the windscreen if possible, as this will help remove the condensation. Use this as well as the air conditioning, if your vehicle has it, to keep the atmosphere in the vehicle dry so the hot air from the heater doesn’t cool and condense on the glass.
By following these simple tips, you can help avoid the delays and hassle caused by condensation, and ensure your commutes aren’t hindered by your windscreen.
How to prevent moisture build up in your car
- Remove moist items from the car, such as coats, shoes, boots, gym kit, swimming kit, towels and muddy pieces of equipment.
- Fill an old pair of tights with cat litter or snow boot crystals; this will absorb excess moisture from the air and is a homemade version of the dehumidifiers you can buy in automotive stores.
- Wash your car inside and out; in particular, focus on the inside of the windows; it’s easy to make these dirty by wiping them with your hand or sleeve, so make sure to clean them properly to reduce condensation.
- Air out your car by winding down the windows for a few hours when it’s safe to do so and weather permits.
