I have never had a vehicle that the windows fog up as easily as BMW's. My Wife had a 2002 330ci and the windows fogged up in it like nothing I had ever seen before.

Seeing as how it is somewhat difficult to effectively clean the front and rear windows (especially the corners) does anyone have an effective anti-fog treatment?

I've noticed my car does it much worse than my wifes. I think I'm going to try some of that Rain-X anti-fog stuff.

Has anyone else gotten the really weird instant fog? A couple of weeks ago on my into work at the same spot to days in a row my windows went from completely clear to totally fogged in seriously about 2-3 seconds. I've never seen this happen before. It also happened to one of my co-workers with a new Mustang the same two days.

humidity. BMW auto climate control pushes air out of all three vents (defrost,dash,footwell). Humid/warm air hits your cold windshield and u get insta-fog. A/C on will fix that.

Yeah that's what I did. I just thought it was amazing how quickly it fogged up. It was like something from Mr.Wizard.

i just keep my window clean. i clean the insides about every other month and i never have a problem.

Glass Science makes a product called Fog Clear, which works pretty well. I've used it on a shower mirror and racquetball goggles and it holds up quite well even under lots of moisture and hotter conditions than a vehicle typically sees. Usually I find I have to reapply it every couple of months for maximum effectiveness.

I haven't personally used it on my vehicles windows yet because I haven't had any fogging issues.

+1. fog is a zillion times worse when your windows are streaky. Invisible Glass is the first product I've used that leaves windows clean enough that I never see fog streaks.

I still get it through the Stoners Invisable, I guess I really need to get one of those triangle glass cleaner things, because my big dumb hands don't get the corners real well.

My windows have never fogged, not once since delivery.

I leave the ac on and always auto.
