Windshield fogging up in cold weather

[GarageMahal]

Interesting idea. This stuff works great for keeping ski goggles from fogging up in the worst conditions

struggled with the windows last night when I had a truckload of people I’m gonna put some of this on my windshield tonight. Will update

Wow! Havent seen that stuff in 40 years but I recall that worked great on my ski goggles back then.

Hey, all. Different take entirely here, but....I seem to have this problem much more when the windows are dirty. It started up a couple weeks ago, so I repeated what I did last year - mix a gallon of water with a tablespoon or so of white vinegar, and a drop of dish soap. Use a chamois, dipped in this solution, to scrub each window, then reverse the chamois to finish up.

When I do this, the glass is so clean that it almost CAN'T fog up. It takes a lot of hot air to make it fog at all. And, you have really clean windows.

My theory, being a computer engineer, not a weather guy, is that really clean glass has less contamination to allow the moisture to condense and fog up the glass. Sounds good, but who knows?

I'm gonna give this a try this weekend. Thanks.
