What Is Winter Fog?

Winter fog forms on the inside of windshields and windows due to warm, humid air lingering in vehicles as frigid winter temps cool the glass from outside. You can wipe away this fog as a quick solution. To clear your view more quickly from the inside, put your AC on full heat and direct the air as fully as possible onto your glass surfaces. As the air from your heater warms, the air will be able to remove and evaporate more of the moisture collected on your glass. You can also try turning off the air recirculation mode . This pulls dry air in from outside your vehicle instead of recirculating the humid air trapped inside. Car-Lotta reminds you that if you'd rather avoid the hassle of fog altogether, there are plenty of inexpensive products available that ensure you won't have to deal with fogged windows on a busy morning ever again.
