Rain-X AF21106D Glass Cleaner

Works great

This stuff is magic, I use it on my bathroom mirror and there is no fog after showers, and I have no vent fan in my bathroom. It lasts a few weeks before needing to reapply. You have to use a generous amount, it does leave some very faint streaks that are not visible unless you’re looking, but I tried using less once not to have those and it didn’t work.

Rain-X for the outside windshield is a superior product and I'm a faithful customer. This product from them is not that great. It can prevent fog, but it creates a film that comes back, and you can see it during daytime driving. You have to make sure you apply it correctly but even then, you will need to address the film that builds up after a week or so.

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

I put this product on the inside of my vehicle's windshield to keep it from fogging up so much. Not only does it not work, the defroster won't take the fog off. I have to carry a towel in my vehicle and wipe the windshield because I go anywhere. I'm hoping vinegar and dawn will remove it or I may have to get a new windshield.

I applied this product at front window in my car. I think it worked well at first. It was obvious that front window didn’t get fog but rear window got fog. However, front window got foggy again. Is it because I wiped the window with dry cloth later? I don’t know. I assume I need to apply this cleaner often after I wipe the window every time?

This will save your head!

Great

It sadly doesn't work on indoor sliding doors, which is what I really needed it for. However, it does work on mirrors.

Love this product. Works as described. Worth the money. Would make an odd, but thoughtful gift for new homeowners. Why not?

Does not work properly Don’t even last 24 hours

Not working good

When the product was delivered, the bottle was not properly sealed, half of the product was gone and the box was wet with an ugly smell.
