Re-apply as needed to maintain fog-free condition. If any haze appears due to excess application, sprinkle with water and wipe with a dry cloth or paper towel until clear
Overall rating based on 50reviews
This product would cause severe reflection of light on windshield. It would be hard to see things when there were strong sunlight at days or road lights at night.
Works but you meed to redo on glass/mirror every 3-4 days
Made my arms tired
This stuff works wonders as long as you can get all the hard water stains off your glass doors. That's the catch. The bottle does not leak and it is easy to use and apply once everything is clean. I feel like it saves time because you're not scraping away the fog or hard water constantly and it keeps your glass shower doors looking very nice. Works great for in the camper or any sliding glass door really. I highly recommend this product for anyone who likes to have shower chats and or see what all the noise is about instead of looking through the FOG
Inside windshield
worked on our shower mirror
Perfect.
Works very well. Purchased for bathroom mirror. Clear.
Overall good product. Easy to spray and wipe.
Love this stuff I sware by it always works
Appears to be a good product and it should work well.
Cleaned the interrior of my car but still kind of fogs up.
I use it on both my motorcycle helmets. It keeps the face shield clear and free of fog
Defrost wasn’t working in my car so I purchased this. It worked great
Great
Works great. Easy to apply.
Great product
First time using this. Seems to work.
Product does the advertised job. Use the shower, hot water, steamy bathroom… clear mirror. Great right? Except that once the humidity is gone, the mirror has a haze.
Works initially but window fogs up granted significantly less in a few weeks
So the last time I bought this, it was in the smaller non-spray bottle. Not sure if that makes a difference or not because this last one I bought has been a huge disappointment. I don't remember it leaving my windows super greasy and with smudges all over them most notable at night time. It is very distracting and makes my windows look filthy. I followed the directions to a T and even redid it over a few days later. I am on the fence because on one side it does prevent fogging which I am very happy about but on the other hand the side effects of using it (smudges/streaks) are sort of not worth it, and I have OCD so seeing those streaks on my window every night gives me anxiety haha. I can not decide if I would recommend this or not.
Great product
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.
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
Not 100% but I think it’s less foggy in the morning. Less time wiping the windows
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.
Good product
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.
I use the product on a mirror in the shower. The Rain X keeps the mirror from fogging up so I can see my face when I shave.
I got this for my wife because she drives a school bus and had bad problems with windows fogging up. She applied it and said it work perfectly. She has added it to her bus driving bag, for future trips.
I use this product before but this time streaks were horrible and still have not cleared up.
Works great for de- fogging car windows!!
I think it works, I have had not problems except that it is a little hazy when I put it on my windshield. But maybe I did it wrong.
Works great
Tried other products and techniques to keep my windows from fogging, some worked by didn't last very long. Rain X Antifog worked great and last much longer than any other product.
This gets the job done as described…in fact, my husbands took it for his car! Now I need another bottle🙄
this product does what it says even cleans the windows this really does work
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.
Thai product works - I couldn't believe how it took away the fogging in the car immediately
Windows really don’t fog up now
Fine
works
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.
Works great! Perfect for my car
I’ve been using this for years. I use it on my 69 ford because the defrost isn’t up to par. The anti fog is a miracle worker in the mornings. Definitely recommend.
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.
It does work for a steamy bathroom. However, it leaves a film on the mirror when dry.
It works fantastic, but only for about a week.with louisiana humidity, i've got to reaply, but it isn't that bad.
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.
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..
