On cold and rainy days it is very common for fogging to occur on your car windows, which can make you lose visibility on the road and put you and everyone else at risk. The temperature and humidity difference between the inside and outside of the vehicle is the primary cause of the fogging.


Besides the cold glass, the temperature inside and the contact with the outside can also lead to windshield fogging. This occurs because when breathing out the air comes into contact with the glass, emitting steam and producing condensation on the vehicle's windscreen. If you want to defog your car's windshield fast you should follow the steps below.


Let air circulate inside the vehicle

To defog the windshield of a car quickly we suggest you let air circulate freely inside the vehicle. To do this, you should lower some windows to let into the car the outside air and have this mix with the heat and humidity of the interior. Hopefully, in a few minutes your car will defog completely.


Apply air from the heating system

If the first trick does not work or you see that the glass has trouble in defogging apply the hot, dry air from heating system directly onto the windscreen. If you do not know how to do this you must activate this action by selecting the icon that represents a window and three arrows pointing towards it.


Apply cold air

Through the cold air or air conditioning system of the car you can also defog the car windows. Of course, know that if you apply cold air on the glass the moisture will be eliminated more slowly, because cold air is not able to hold as much moisture as warm air.

Clean the glass with soap and water

Rubbing the glass with your hands you will remove condensation but only momentarily, so it's not the best way to defog your car. We recommend soaking the windscreen with a mixture of soap and water before starting to circulate. After pass a dry cloth to remove the solution. With this action you will stop the car from fogging for some time.


Finally, remember that the engine should be at a temperature of about 90 degrees approximately for the windscreen to defog properly and quickly. If your car has air conditioning, defogging the windscreen of the vehicle will be much easier.
