If you want to remove moisture from car, you have to know
what causes it in the first place. Warm and humid air gets condensed after
coming in contact with a cool surface. When the weather is cold, the warm
breath of the driver and passengers meets the cold windshield and window
glasses and gets condensed. It can also happen if there is already something
wet or damp in the car gets heat from sunlight. Without a ventilation system,
the moisture can’t escape and turn into thick mist and water when touches the
1. Turn the Defrost Button ON
It’s the easiest way to keep the vehicle moisture-free. It
will switch on both the heat and the AC systems. The AC will clear up moisture
from the air and the heating system will keep the interior comfortably warm.
2. Create a Passage for Ventilation
If it’s a sunny day or the weather is warm, leave a couple
of windows slightly open while driving. It will keep the interior warm and create
a passage for the moisture to get outside. However, don’t do the mistake of
keeping the windows open at night. It will make the windshield hazy with dew.
3. Keep Everything Close in Wet Days
The rainy days are the worst for creating condensation
inside car. So, don’t leave the windows or the sunroof open on these days. It
will let moisture in and make all the surfaces foggy.
4. Discard all the Wet Items
Leaving damp or wet items such as shoes, clothes, floor
carpet, and other things inside is one of the main reasons for condensation
inside car. As you already know the cause of foggy glass surfaces, you should
remove every source of moisture to keep the glasses clear. Check for coolant
leaks and other types of discharge from the vent system, windows, or sunroof.
Repair and seal the leaks because these damp things will create moisture, which
will then transform into the fog.
5. Turn off the Re-circulation Valve
Your car certainly has this valve if it has the air
conditioning system. Nevertheless, many people don’t have a clue about its
position. Well, look for a switch featuring the picture of a C shape with an
arrow or a person getting hit in the face by an arrow. It does the job of
recycling the inside air and recirculate it. You have to switch it off to allow
dry air in from outside and remove the indoor moisture.
