Why is There Ice Inside My Car?

469

It can be frustrating when you get in your car in the morning to find ice on the inside of your windscreen. Whilst we might expect to de-ice the outside of the car, it can be worrying when the ice is inside. Below, we investigate why our windscreens can ice up on the inside and how we can prevent it from happening.

What causes the inside of a windscreen to frost?

The inside of your windscreen can ice up due to the humidity inside your car. The moisture will evaporate and then condense on the windscreen. This then freezes when the temperature outside is very cold.

Moisture can occur inside your car for a number of reasons. Your breath will cause moisture, so the more people in your car, the higher the moisture levels. Wet clothing left inside the car will also increase the humidity.

Sometimes there may be excess moisture in your car due to problems with the ventilation or drainage. In this instance, you may notice that the seals around the doors or windows are damaged, or you may notice blocked drainage holes. If this is the problem, getting the fault fixed at a garage will help to stop the inside of your windscreen frosting.

How to stop the inside of your windscreen from icing up

To stop the inside of your windscreen from icing up, you can reduce the moisture in your car. If it has been snowing, try to remove as much snow as possible from your shoes before you get in the car. If you leave it on your shoes, it will fall off into your car where it will melt, evaporate and then condense on your windscreen.

You should also avoid letting water sit in your car if it has been raining. It can be helpful to use plastic lining over your fabric car mats. These will be easier to shake off any water outside of the car, rather than it being absorbed into the mat and causing humidity.

You should try to keep your car clean and free of rubbish and debris. These can all absorb water and increase the humidity inside your car.

When you’re driving, you should try to keep the AC on along with the heater. Most cars will allow you to have the AC on a warm temperature. The heaters will warm the car up, but the AC will help to remove the humidity.

You can get special humidity absorbers for your car, which can help to reduce the moisture. These usually contain some kind of silica gel and some are reusable.

You should keep your windscreen clean, as any dirt will absorb moisture. Thoroughly clean the glass to remove any grime. You can then follow this with a layer of shaving foam, before buffing it away with a microfibre cloth, so the screen is clear again. The foam will help to create a barrier that stops the moisture from sitting on the screen and freezing.

How to remove frost from the inside of your windscreen

The best way to remove frost from your windscreen is to let the car heat up. If your car has a heated windscreen, you should also turn this on. When the frost melts, you should mop up any moisture from your dashboard with a towel and remove the condensation from your windscreen with a cloth. You may need to buff it to prevent any marks or streaks from obscuring your vision.

You should make sure to remove any wet cloths or towels from your car, as leaving them inside will cause the windscreen to freeze again.
