Rain-X AF21106D Glass & Mirrors Anti-Fog Treatment, Prevents Fogging & Steaming on Windshield and Visors, Improves Visibility, Great for Auto & Home

It's so annoying to have foggy windows when it rains. I don't like having to continually turn on my defrost. This product was easy to use, although there were some streaks, the product was very effective. It's been a life saver.

You can see the film in the light of the incoming car. But it does stop fog to form on the inside of your windshield in the damp early mornings. It's not perfect, but will let you see what's going on to drive safely. If you are here because you think something MUST be done with for windshield, this product can help you. If you are not desperate, you may not be happy with it.

Don't bother with this product. Although I have used and like the Rain-X for auto exterior glass, this product for glass interior does NOT stop the glass from fogging. Worse yet, I have had to use a microfiber cloth 4 times since application to remove foggy-like residue that remained on the glass and clouds up the windshield. I do a complete microfiber wiping one day, and a day or two later have to do it again, and then again, and then again. I also used it on a bathroom mirror. Not only did it not stop fogging, it required the same constant microfiber cloth wiping until I finally used Windex to remove it completely, which I will now obviously have to do with my car windshield. I got this product on sale - it is actually not worth 2 cents. Be warned!

does a good job helps keep the windshield clearer in the mornings which makes a giant difference when driving

The application of the product proved somewhat fussy, causing me to experience a degree of frustration while attempting to apply it to all the windows of my car. Consequently, I decided to discontinue its use. While it appeared to perform its intended function for a certain period, I have since noticed that it has left a streaky residue on my windows, necessitating cleaning. It is worth noting that if maintenance is consistently performed, the product proves effective. However, the level of upkeep required is beyond my current capacity.

Worked great

I've used Rain-X for 40 years. This is the stuff you put on the INSIDE of your windshield rather than the outside. Works on bathroom mirrors and, among other things, the inside of diving masks and swim goggles

It's not streak free, leaves a film after use, even after so call polishing it off.. the price was good . It leaves a clear shine at first.. then it's a hot mess with windows looking constantly dirtier than before

Amazing item loved it , thank you amazon for selling geniune products

Muy efectivo, solo si el vehículo está estacionado se empaña, pero si está en circulación no se empaña

Easy to apply. Results vary depending on the surface. I used it on my helmets, on some it worked wonderfully well and on some it left a fine layer or fog. Didn't work at all on my specs, don't know why. Can anyone suggest?

المنتج يعمل بمنع الضباب الداخلي.

Tried it this week and it works well, no fog. Easy to apply, make sure the interior window is clean before you start.
