Hi again,
I’ve tried so many different products that claim to elimanate fog from my windows. At first I thought only that it was b/c my windows were dusty or not “squeaky clean”, but after cleaning them almost obsessively it still didn’t help much on my drive back home from Florida. Then I researched the science behind fogging/precipatation. So turning the heater on solves things (after the car warms up). But it still makes me wonder, why isn’t anything working and is there a cheaper solution than buying some anti-fog stuff on the net that GUARANTEES it will work. Any help is appreciated.
