Chargèro : Fog and humidity is nothing, try coming up to Canada where we have freezing rain...fun times. Also when snow hits the warm glass of the car you have just been driving, or when it's warmer during the day and the temp drops at night, this causes frost build up on the outside of the windshield (usually at the bottom near the wipers, usually freezing them in place). Harder to remove and takes longer. If you have cracks or chips on your windshield, an excellent way to turn them in to a spiderweb is to beat at it with a scraper or blast the defrost heat directly on to the windshield. Also cranking the wipers when they are frozen in place or covered with heavy wet snow is a perfect way to break them or burn the motor assembly. Frost builds up on the INSIDE of the car when you have water/melted snow in the foot wells, or the floor mats are damp. When you lave the car parked, and the temp. drops at night, the rising moisture freezes to the inside of the window. The best remedy for preventing it is to keep the inside of the car dry as much as possible, like putting news papers in the foot wells, and silica packets on your dash to absorb any rising moisture that may reach the windshield area. Hopefully you learned more from the info in my comment above than having wasted your time watching this video.
