Invisible Glass 92472 Anti-Fog Interior Windshield Treatment Car Glass Defogger Cleaning Spray Prevents Windshield Fogging To Improve Driving Visibility, No Streaks or Haze, 8 Fl Oz, Pack of 1

This stuff works great. I used it on my windshield interior, which hadn't been cleaned in 6+ years and it cleaned the glass to where I can see through it again.

This didn’t block the fog at all .. smells like rubbing alcohol- maybe someone switched the contentsNot happy

Easy to use and works!! Dries quickly and cleans well.

Applied as instructed. Did not diminish fog. In fact made it worse because of streaks left when I let it dry on mirror instead of wiping dry.Solved the problem in shower. I have a small mirror in shower that I use for shaving. Actually, it is a peel and stick that I bought on Amazon. While I'm in the shower I use my hand-held shower head to run my shower water over this little stick-on mirror for about 10 seconds. Result: mirror is fog free for several minutes. If necessary, I do it again.Haven't tried anything with big mirror yet but wonder if warming it first with hairdryer will work? Not like I use that mirror for anything. I have no teeth and im bald. LOL

The thing is, it's probably best used in the summer or fall when your windows don't actually get fogged up much. In the winter, it will work until probably the first time your car gets fogged, and then eventually the condensation will wash off the product, so you'll either have to apply it again every few days or just suffer with fogged windows. I'm not quite sure if it's pointless or not, but it gives underwhelming results. I'm just going to say it helps a bit, but I'm not sure if I'd buy it again.

I bought this to help with the condensation on the windows in my apartment and for my car windows. It works great for both. I highly recommend this product.

The application works well in a large area and if you have very long arms. If not, you will get lots of foggy film residues

Worked really well
