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

Mammoth around Christmas, my windshield was foggy round the edges. 3 months later I used this stuff, went to Tahoe, it was minus 10 degrees, but on the glass, no fog, whatsoever. None. This stuff works. It goes on crusty but polishes up real well. Like invisible. No effort neither, just a 2-minute job. YT's Scotty Kilmer recommended it. He's hardly ever wrong. Great stuff for preventing fogging.

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!

I don't find these effective cuz it smears the window of the windshield making unclear visibility.

Didnt work for me and left streaks

Works well like all Rain-X products. Works as advertised. This bottle should last for years. a small amount works to do large areas. Highly recommended

This is a completely worthless product. It just makes your windows fog even more. It takes a lot of work to get it off after you put it on.

Bought it for our bathroom, shower mirror and what I have to reapply. It maybe once a month and lightly wipe it down.And we have a clear mirror out of the shower. Highly recommend for that purpose

Sinceramente pensé que no iba a funcionar ya que he probado diferentes productos en el pasado y ninguno ha cumplido lo que promete; este, sin embargo, ha funcionado a la perfección. Lo recomiendo ampliamente.

Like most Tain-X products, this is also consistent and works fine. Needs to be re-done every few weeks.

車のクーラーが壊れて、窓ガラスが曇るので購入。雨が降って湿度が高いものの、11月でそれ程それ程寒くない日で1人で乗車す分には、問題なく効果を発揮しました。もっと寒い日、車の乗車人数が多い場合には、窓を開けたり、乗車前にフロントガラスを十分事前に温めたりする必要があるかもしれないです。

I have used this product and it is highly effective. On a heavy rain I have tested from inside and it was like magic. No fog deposited with windows open on a rainy day. I love this product and will test in my J&K and Leh Ladakh trip on my car. This is a life saver in rainy and winter days. I highly recommend this product. Though the price seems higher compared to other brands but this is gonna last for more than 3 seasons.

Works well on the glass inside our sauna. Stops it from fogging up
