An amazing product that delivers on its promises.

May 21, 2025

This is an amazing invention. I drive a classic car that doesn’t have a front window defroster, and this saves me from having to spend countless mornings, wiping the fog from the inside of my windshield. In fact, I use it on the inside of all my windows and I have perfect visibility, no matter the temperature or humidity of the outdoors.

Not so easy to apply

May 14, 2025

Follow directions exactly, make sure the weather is not too cold, and also read the directions exactly. Meaning clean your window on the inside first and do not use this as a cleaner, this is a anti-fog material and it has to be on a clean window

See more clearly on those rainy drives.

I found this works great to prevent fogging, especially for the side and rear windows. You may find it will leave a residue that can annoyingly obscure your sight through the front window so be certain to wipe down the windows. Rain X also works great on bathroom mirrors and lasts about one month with each use.

Does it's job

April 06, 2025

Works good. Sprat it on a few paper towels, wipe it on, then wipe it with clean paper towels. It's been raining here for days and haven't seen much fog. Huge difference so far.

This product worked great for my car. I drove to the mountains in CO and didn’t have to use my defroster once. Didn’t leave streaks of any kind. I would suggest buying this if you are in cold temperatures often.

This product works quite well

December 21, 2024

I am a supervisor for the United States Postal Service and the most important thing is employee safety. The mail trucks my carriers use are quite old and the defrost does not work as great as it once did. I ordered this the try out and see if it'll help. We use this on several of our vehicles in the carriers, all stated That it's made such a big difference in visibility. I will continue to use this product and recommend to everyone, but especially those who work added their vehicles.

It wears off rather quickly, but it definitely does work. Make sure you apply it correctly otherwise there will be streaks. But if applied properly, it's perfectly clear.

I recently purchased this product to help stop my windows from fogging over especially early in the morning. I followed the directions and it works great. No more foggy windshield in the morning. I highly recommend this to anyone to eliminate your windows or windshield from fogging.

Not really recommended...

November 17, 2024

No matter how much I wipe, the streaks don't disappear. It makes everything look hazy, and at night, it scatters the oncoming headlights so brightly that it hurts my eyes. I'm not going to use it. I might just use it on the side mirrors, no windshield..

No more fog

This product works perfectly 100%!! When I first applied it, the consistency and viscosity of the product scared me. It's almost oily. I applied 2 coats wearing latex gloves and wiped clean. My windshield is had always had a fog area due to the defroster and with this it vanished immediately. Thanks Rain X!!

I tried to cheat the system and spray this on my bathroom mirrors so I could enjoy clear mirrors after my shower. It only lasted one shower and then the volume of condensation created from a shower was just too much for this. It's great for its intended purpose on vehicle windows, though! 😆
