Im trying to figure out what kind of “anti-fog” products are out there, and what actually works. I like to drive with my windows down, but its hard to do in the mornings with all of Houston’s humidity. My defroster cant keep up with the humidity coming into the car, so I end up having to keep my windows up.

Is there any anti-fog type products that work well? Being safe on tint would be a plus so I can use it on the rear window as well.

The only thing I know of is a Rain-X product anti-fog product that I've seen at Autozone.

I used to keep a can of shaving cream in my Bronco for this very reason, but it must contain Menthol. Try it out on your bathroom mirror before your next shower.
 
wtf, so no one makes an anti fog coating?
 
I run my A/C and turn the heat up. I don't know what it is about this, but it works and I've been doing it for years. Keeps the car comfortable too.
 
lol, that would work if i wasnt in houston. its already hot

This would be exactly what the "defrost" or "defog" setting on your climate control would be. A/C works by drawing moisture out of the air, the same moisture that's accumulating on the inside of your windshield.

This is the only thing that actually works. I use the gel instead because that is what I have on hand. You can also used a diluted dish soap and water. The shaving cream and dish soap acts as a surfactant and prevents the fog from forming up. Dont use the rain-x for fog, absolute garbage.
 
I've heard that a qd can do the same thing, I'll have to try and see what happens
 
The heat works because it heats up the glass and doesn't allow the evaporated water in the air to lose its heat energy to the glass (condensing the evaporated water and becoming liquid on the glass).

As for preventing fogging up, the reason it fogs is because when the water condenses, it becomes extremely small beads of water. Your best option is to avoid glass cleaners on the inside of the glass that contain silicones or waxes as they make the surface bead. Most aerosol cleaners also cause slight water beading (I'm not 100% sure why, but I'd assume it's to do with the propellent).

I've found both DP Krystal Vision and the Meg's glass cleaner concentrate (made to the recommended 10:1 dilution) to be good non-beading cleaners. To stop the fogging that is currently happening, if you can find a black and white newspaper that's still produced using old printing processes (ammonia based inks), using that with your glass cleaner (or distilled water) may help to remove any oils, otherwise time is the only option I can suggest.

As for the QD suggestion, if it causes water beading on paint, it will make the fogging worse.

Thank you! I was beginning to think people thought I was pulling their leg or something.

I've never tried the dish soap though...TO THE BATHROOM!
 
I shave with a mug and brush (That's right. I'm That old).
Once over with a brush full of Old Spice keeps my windshield
clear for about a month.
