    Im trying to clean a windshield of a vehicle that’s been sitting outside for years, and it has a foggy area it looks like a stain with drip marks. It’s on the outside, I’ve tried razor blades, mineral spirits, vinegar, even polishing compound. It’s a little better, but still large and too bad to use in current condition. When water or glass cleaner is on it it’s gone, but when dry it’s back. Any ideas?

    Sounds like something has etched the glass.

    Years ago the windshield doctor guys advertised polishing streaked w/s glass. Maybe someone still does it ...

    Acid rain etched the glass. Replace it.

    We had a bunch of police cars that were used for skid training. They ran on wet surface all of the time and the water got on the windows daily . The water fogged the windows and nothing we tried and we tried everything worked . We had to replace the windows when they got bad enough that it hindered the vision of the students. It permeates the glass and you can't get it out.

    I've heard Oxyclean works on foggy head lights so you may want too try that.

    We tried just about everything . We had chemical companies coming in with every product you can think of. Razor blades ,steel wool , Rubbing compound wouldn't touch it . Would only leave scratch marks on the glass. Once it is in the glass it won't come out. We even had a lab analyze the glass and it soaks into the glass. It was a major expense to change out all of the side glass in 40 cars.

    Worked in a Refinery in S/W Louisiana for 33 years, all our vehicle windows would get etched from cooling towers and stacks. We bought a compound called Cajun New Glass followed directions and it worked great. Don't know if it is still out there worth a look.
