The heater/defroster in my car stopped working and it was almost impossible to get the windows to defog in the morning. I cleaned my windows really well, applied a decent layer of this stuff, let it dry, then used a clean paper towel to buff the film away. Worked like a charm! My windows were crystal clear this morning! Worth every penny.UPDATE: one week later and there seems to be an odd film on my windshield. It didn't show up until about 2 days after using this stuff. My driver and passenger windows do not have the film but my windshield does. I'm going to clean it a few times and try to apply this stuff again to see what happens. Not sure why it worked so well on the other windows but not my windshield! Will post another update after I give it another shot.ANOTHER UPDATE: it's been about 2 months since my last update and I think I've got this stuff figured out! After cleaning my windshield again really well to remove the film, I reapplied this stuff the same way I did originally but buffed twice as much as the first time. They were crystal clear for about a month until it started to wear off! So I just did the same thing and it lasted about another month.So if you clean your windows REALLY well prior to applying this stuff, then buff the film off REALLY well after applying, it should last about a month before it starts to wear off and you slowly notice it fogging. This is the most effort I've ever put into a $5 Amazon product review but I hope it helps someone lol!

Yesterday was the first day of the season where my windshield fogged up as it was raining. I applied this product as directed and then immediately went on a drive. I did not need to defog my windows at all. There is a slight haze when there is a big humidity change between inside the car and outside but you can still see just fine. In the photo you can see the difference where the product was not applied at the bottom of the windshield.

Used this on our mirrors and shower stall doors in bathrooms. Worked like a charm! Wanted to try in my car, but not sure how this might work. Maybe I'll use it on a friends car first ...........that's kinda ugly, huh?

I've now tried close to a half-dozenl spray products such as this - mainly to try and keep fog off of bathroom shower mirrors. I've now tried 5 different brand names, including this more well-known Rain-X interior anti-fog spray.In each case - again, I happen to be using it in a shower stall setting - the effects of keeping steam/fog away - lasted for only a day or several days at the most. It actually became quite frustrating really. I applied as directed and when I first tried taking a shower, the first day I was screaming "whoopee," because I thought I finally found the solution to constant fog on the mirrors (which I use for shaving in the shower). And the shower mirrors I use (I have a huge walk-in shower) are never even touched by water. However, it was all to no avail, and the Rain-X only lasted only for several days before the fog began coming back with a vengeance. Sure, I tried applying it again - but again, that only lasted a day or two more.Now, from what I understand (and based on some past use with cars), this Rain X works fairly well for keeping fog off of the inside of car windows. But if you're thinking about using it to keep fog/stream off a shower mirror (even those that do not get water on them), just forget about it.As an aside, if you're considering purchasing a separate fog-free shower mirror, rest assured I tried those also. Many of those inexpensive Asian-made fog-free shower mirrors (as they are called) being sold in droves on Amazon and eBay, are nothing more than conventional mirrors with a similar anti-fog solution sprayed on at the factory. The end result on those is that after several days to a week, the solution wears off and the fog begins to form also.So there you have it. These sprays are good for car windows and car mirrors, but if you're looking for a solution that prevents steam/fog in a shower setting - these products won't last for more than a few days. So keep that in mind...Still searching for the right solution for a shower setting that actually works long term.

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 statedThat 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.

This product did not work for me as advertised. Tried to return within normal return window but was refused. Reason given was because I had opened the product it was not returnable.How was I to know if it worked or not without opening and trying it?!?!?.BOOOOOOO!

Not having a very strong defrost fan in my 1952 GMC, my windshield tends to fog up on rainy days. Tried this product on the front windshield and it really works! See photo of front windshield clear vs side window where this product was not applied.

It does work . Definitely better than not having anything at all . If your cars defogger does not work this is a great product to use in winters & monsoon . You need to reapply after some time . Can also be used on your bathroom mirrors & eye glasses .
