i cleaned my mirror in my bathroom with formula 409 orange power all purpose cleaner and the next time i showered instead of being entirely fogged it was clear as before i showered. so i thought about it a little bit and tried it on the x windshield and it hasn't fogged yet (its been a month now) just thought i'd pass it on.

btw- does anyone else have any products that work for things they weren't intended to like this?

I have the worst luck of anyone for my windshiled fogging up. Almost every morning, no matter what the temp is (above freezing), it seems to start fogging up. Sometimes cold air defrost works, sometimes that doesnt work and hot air does. Sometimes both of those cause the window to totally fog up so I cannot see out of it at all. Windows down? Maybe, I cant tell...

Anyway, on what side of the windshield did you apply it?

inside for me, i actually use meguires wax on the outside of the windshield as well.
