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

This stuff is awesome! My windows fog from the cold temp inside & hot/humid temp outside so I tried this & it'll keep my windows fog free for 2 days. I do have to rewipe down at the end of day 2 but no biggie. I'd recommend 👍🏻

Applied to my front windshield and it works. I wouldn't say it's crazy good but it's good enough. Would recommend using microfiber rather than the instructed paper roll to feather the liquid better.

In order to remove the streaks, you absolutely HAVE to dry polish after it dries. Many people seem to ignore this step in the instructions but it's actually important to get a smooth finish. I find that wiping the whole surface horizontally then vertically, works better to get rid of streaks than repeatedly wiping in the same direction. Be careful though, since polish too much and you remove the antifog or reduce it's effectiveness. It's not always easy to get the right balance. Even when applied properly, you may still occasionally see some smudges at some angles depending how the light hits the surface. It seems impossible to get absolutely no smudging while maintaining it's effectiveness, but most people will probably tolerate a subtle haze that is only visible at certain angles. When the antifog works, the surface still becomes wet, but it will stay clear when moist. But there is a limit to how much moisture it can handle; you can't let the surface get so soaking wet that the water starts dripping, which will wash it off and you will need to reapply. Does not work on some coated surfaces like eyeglasses with anti-reflective or hydrophobic coatings; the liquid beads up and doesn't coat the surface. The bottle tends to drip all over the place

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.

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!

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.

This Rain-X Original Glass Water Repellent is a really effective and easy-to-use automotive product that makes a noticeable difference in driving visibility during wet weather. The biggest benefit is how it creates a hydrophobic coating on the windshield, causing rain to bead up and roll off quickly instead of spreading across the glass. This greatly improves clarity while driving in rain, sleet, or snow, especially at higher speeds where water tends to move off the windshield more easily. Application is simple and fast. You just apply it to a clean, dry windshield, wipe it on, and buff it off. It dries quickly and leaves a clear, streak-free finish when used properly. Many users appreciate that it doesn’t require complicated steps or special tools, making it convenient for regular maintenance. Once applied, the visibility improvement is immediately noticeable. Wipers don’t need to work as hard, and water tends to bead and slide off more efficiently. This can help reduce glare and streaking during heavy rain, which makes nighttime and highway driving feel safer and less stressful. The compact bottle size is also very practical, making it easy to store in a glove box or keep in a car kit for quick touch-ups. It’s a small product, but it lasts a good amount of time depending on usage and weather conditions. From what many users and drivers commonly report, the biggest strengths are the reliable water-repellent performance, easy application, and improved driving visibility in harsh weather. It’s especially popular among daily commuters and road trip drivers who regularly deal with rain. One thing to note is that, like most windshield treatments, it works best when applied correctly to a fully clean surface and may need reapplication over time for best results. But when maintained, it performs very well. 🌟 Summary

This is the third bottle I’ve purchased in 10 years. Every winter (or as needed) I apply Rain-X to my windshield and rear windows so I can see clearly in wet conditions. I do it for my parents’ cars as well as it is just a small but effective safety feature. I live in Southern California so I don’t need to apply often, but 1x maybe 2x a year I’ll apply it, and the water runs off my windows easily. It also makes it easy to clean my windows as well. If you drive in the rain or snow it is a must have product. I also use the Fog-X for the inside of the windhield to reduce fog in the cold months as well.

Good product

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

Me gusto bastante. Es un líquido como tipo aceite, pero se limpia súper facil después de haberlo aplicado. Y con muy poca cantidad cubres perfectamente todo el cristal parabrisas. Queda limpio todo el cristal. Estoy satisfecho con la compra. Llegó en perfectas condiciones sin daño ni derrame. Gracias!

Wont work at all
