Rain-X 630046 Interior Glass Anti-Fog, 12 oz. - Prevents Fogging of Interior Glass and Mirrors, Usable on Both Automobiles and Marine Vehicles

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.

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 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.

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.
