The best way to make your windshield more fog free to prepare for future driving is to FIRST clean the windshield with a window cleaner on the inside of the windshield. Do this many times to get off any type of dirt or grime that may be on the inner windshield. Make sure to clean any of the window cleaning residue off to avoid streaks that will blind you when you drive in the direction of the setting sun. Once the windshield is clean, get a product called Rain-X for interior auto glass. Use the product on the inside of the windshield after it is perfectly clean. Once applied, you will notice that after cleaning and using the Rain-X product that your windshield will not get as foggy anymore or it will be minimized. When the weather is cold and if the fog forms on your windshield, it will clear away ultra fast.

Condensation on the inside of the windshield?
When the condensation on your windshield is heavy turn the blower on and set it to blow on the windshield using your car air climate controls. The lower the humidity of the air blowing over the windshield the better. Use as much blowing air as possible and use warm air in most situations. Warm air carries more water than cold air which helps to remove water with air. It will heat up the windshield fast and this reduces condensation so it will not come back when you turn down the airflow. If the air conditioner in the car is ON it acts as a dehumidifier.

Condensation on the outside of the windshield?
Turn on the blower and set to warm. This will work properly when the engine is warm. Turn it on right when you start the car so that you don’t blow hot air on a cold windshield when you turn it on later.

Not sure where the condensation is?
Turn on the air conditioning and set it to blow on the windshield and set to warm. When the car warms on your windshield will be clear of any fog or condensation. Make sure the fan is blowing air out of the defog vents. If not there may be a problem with the controls to get the air going in the right place. If the controls are working properly the cars AC should automatically come on in defrost mode. The defrost in most cars work the best in the heat position.
