Hey, I was wondering if anyone hve solutions to defogging the back windows including the sides and rear cuz right now as where i live its cold and when i drive to work and back my windows in the back are usually fogged up and I hate it. I have tried almost everything i can think of... 1. blasting the A/C on the front... 2. turning on the rear heating(helps a bit but it drains my energy+gas like mad) and when i turn it off it fogs right back up.. 3. then the other ways i have tried is opening the back side windows a slight bit... 4. Can't wipe the fog off as I will leave finger prints and can't do it as i'm driving.. 5. Last I tried holding my breath but well that didnt last to long haha...

anyways anyone have some solutions for their car?

Thanks

You can try Rain-x Antifog...but that doesn't work too well for me and it gives you a blurry image.

Well I have this Eddie Bauer sponge thing that wipes the fog off. It works pretty good for like a few mins.

If i recirculate the air flow my windows steam up, if i select outside air flow they demist within a minute or two.

keep the front defroster on (even if the front window is clear) and use the "fresh air" option instead of recirculate like ejaymclane said. the window defrost mode keeps the air dry because its already running the AC compressor to take the humidity out of the air.

ok heres how it works. if its hot and humid outside and its cold inside, ur gonna get fog(condensed water) on the ouside of ur windows. if its cold, even just a little humid outside, and its warm inside, ull get fog on the inside of the window. the best way to prevent that from happening, keep ur car inside around the same temp outside. when u blast the heat on ur windows it heats them to the point where water wont condense on them, but that almost impossable to do on the whole car. oh and that fog spunge is ment for that filmy crap that develops on ur windows inside over time. i have one and it works.

i agree. this may sound stupid but when my windows use to fog up ( inside )..

i use roll down the windows to somewhat equal the temps and it clears up the fog.. sure its a bit cold for a bit but works for me

Most people say that using shaving cream, a light layer over it works, never tried it, but might be a good solution. Most of the older cars are prone to fog, due to a different type of circulation used in the newer ones.

I'll have to test this out tonight when i go to work. Thanks for the other solutions but keep them coming if you can think of more

... Well i have tried to roll down the windows in the back to clear the fog but it got to cold so i can't do it anymore...

try this, i might b crazy but... blow dry you interior...if you have moisture in the car (humidity as mentioned earlier...) that might be the problem, what i did was left my windows wide open a dry summer night, and this winter ive had no fogging issues. and if i do get fog, the defogger workspretty good for me. last winter i was having the samed fogging problem you are having

well i have tested out the method which was mention on my last post and it worked!! it was freezing cold outside -10C.. so i turned on for face and feet on full heat (obviously) and instead switched to air intake from the outside instead of inside and it worked perfectly as mentioned. There was no fog whatsoever anywhere on my car. But then again this is just the first try... i'll have to test it at least a couple of more times before confirming that this is one of the best methods to go if you have this problem. Anyways thanks ghettosled and everyone else who mentioned different ideas!!
