Ok this is getting pretty annoying. My windows fog like crazy and it takes about 10 minutes to clear up. when it does clear up and I turn off the defrost, about 10 minutes later It fogs back up while im driving. Is there any type of spray I can put on my windows so this dosn't happen?

 

i just leave my defrost on until it turns off it self

 

puch the button on the ac controls that has the arrow coming in from the outside of the car, not the one with the circle inside the car.
if that doesnt work 100%, open the window a crack. if its cold and snowy there, the dry air should keep it fog free.

 

Rainx makes antifog crap for the interior.
