630543 Interior Glass Anti-Fog, 12 oz. - Prevents Fogging of Interior Glass and Mirrors, Usable on Both Automobiles and Marine Vehicles (Pack of 2)

My son’s windshield kept fogging up even with the defroster on. I bought this for him to try and it worked great! The windshield didn’t even get foggy in the rain. The product didn’t leave streaks either. I would definitely recommend.

Rain-x is consistent at doing its job

I don’t even care if it prevents the occasional fog because what is the point because my visibility is already lowered by the now semi permanent, obnoxious streaking that’s impossible to rub off the glass after you apply this product. It looks like a child tried and failed to clean my windshield. But it was ME, busting my arms for the last half hour trying to get this stuff off.

Windows were all foggy the next morning. Even after following the directions to a T

Works great

The application of the product proved somewhat fussy, causing me to experience a degree of frustration while attempting to apply it to all the windows of my car. Consequently, I decided to discontinue its use. While it appeared to perform its intended function for a certain period, I have since noticed that it has left a streaky residue on my windows, necessitating cleaning. It is worth noting that if maintenance is consistently performed, the product proves effective. However, the level of upkeep required is beyond my current capacity.

Love it

Great product, reduces the fog even in the winter.

Cumple con su función, hay que volver aplicarlo después de una o dos semanas pero si funciona muy bien

Amazing item loved it , thank you amazon for selling geniune products

Easy to apply. Results vary depending on the surface. I used it on my helmets, on some it worked wonderfully well and on some it left a fine layer or fog. Didn't work at all on my specs, don't know why. Can anyone suggest?

المنتج يعمل بمنع الضباب الداخلي.

Tried it this week and it works well, no fog. Easy to apply, make sure the interior window is clean before you start.
