Drivers have been told how they can clear their car's windscreen in a few easy steps. However, if none of these work, and you've tried all that you can, it could be a sign your car needs to be booked in.
The experts from RAC Drive, have noted that the misting up of your car is all to do with water vapour in the atmosphere. This occurs when your body heat and breath warm the air inside the vehicle, increasing its moisture-holding capacity.
When this warm, moist air comes into contact with your cold windscreen, it cools and condenses, creating a 'mist'. It noted that this step is a "necessity" and if you don't fix the issue, "you will be driving illegally."
To "clear your windscreen in double-quick time", the RAC suggests the following steps.
In order to demist your vehicle using your windows, the RAC noted that you should open your windows to let in the dry and cold air. This works by reducing the water vapour inside the car, thus stopping the "misting" effect.
Once the glass is clear, you can slowly increase the interior heat to a comfortable level. If your car does not have the best air conditioning, opening a window is the best way to help when driving. If your vision becomes too obscured, you must pull over safely and wait for your windows to fully clear before continuing your journey.
The RAC further advised that to avoid it misting up in the first place, you should "clean your windscreen with shaving foam." It explained: "This protective barrier won't last forever and may need to be repeated regularly, but a windscreen cleaned with shaving foam will be less likely to mist up."
Get a small amount of shaving foam and place it onto a clean and dry towel.
Wipe the foam across the interior surface of the windscreen.
Use another clean towel to wipe the foam off completely until the glass is clear - this should leave behind a thin protective film to help prevent water vapour from condensing on the glass.
The RAC noted that this will need to be done a few times to remain effective, meaning you may find yourself doing this a few times during winter. However, if your car consistently does not demist no matter what you try, you may need help.
The motoring experts concluded that mechanics will look for airflow restrictions, clogged cabin filters or physical blockages within the vents. The issue may even be caused by a malfunctioning air conditioning system, a broken heater or a faulty internal thermostat. In some cases, the problem can be solved simply by topping up the system's coolant.
