Eliminate Foggy Windows Without Impacting Range

[IssacZachary]

I just have to convince myself that the water droplets have somewhere to go.

It seems the Rain-X AntiFog is working. Maybe it had to cure. I still get some fog and frost, but I notice that there's now considerably more on the rear window, which I didn't treat with AntiFog. But there is one thing I do get. Water droplets on the inside of the windshield. These leave little water spot marks when they dry.

Interesting -- so the droplets are not heavy enough to fall down the glass.

This water is distilled (evaporated) so it might suggest that the spot you are seeing is from collection of dirt on the glass that is collected by the condensate. Perhaps a glass cleaning once a week will help.

On the side windows, yes the droplets run down the glass. On the windshield the angle must affect the way the gravity pulls on the droplets. If there's enough moisture the droplets collect and run down the windshield. A quick buffing gets the water marks off. Maybe that's what's helping the AntiFog do its thing, maybe I hadn't buffed enough.

If your having bad fog problems and you live in a snowy climate I'd suggest using something like Weathertech or rubber floor mats. Snow getting on the carpet and melting really holds the moisture and then when you heat the interior of the car that moisture gets in the air and condenses on the windows.
I was having bad fogging issues when I first got my Leaf and it turned snowy, after I got the Weathertech floor mats(which I think are kind of overpriced but do work) and regularly wet vac them dry of standing water things are much better. It's my belief why ICE vehicles don't fog as bad is because they have so much more heat available that they are actually able to try out the carpet, not so much with a Leaf where heat is a precious commodity.
I don't know about Fog-X but I know with Rain-X your supposed to let the film dry before wiping it off, when I was using it I let it dry over night and wiped it off in the morning and it would probably be best to do this when it was above freezing although I don't know this for a fact.

As soon as I could get the floor mats off of the floor (they were frozen at first) and hung them up to dry I noticed a big improvement! Thanks!

I wonder if there'd be any merit in fabricating some heated floor mats.

The thing is you wouldn't want it on when driving as that would evaporate the moisture in the air, which would in turn condense on the cold windows. No personally I think the best thing is to suck up the water while it's liquid and not let it soak into something like the carpets where it would be much harder to remove. I also took out my Weathertech mats yesterday(60F and sunny, in Feb in MN now thats wrong!) anyway the carpet was basically dry underneath, was happy to see that.
