Rain-X Anti-Fog Trigger | 355 ML Pack of 1 | Reduces Interior Fogging | Removes Smoke Residue | Ideal for Automotive and Marine Glass | Perfect for Home Glass and Mirrors | Ensures Clear Visibility

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.

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 .

Usefull

Do not buy this product. It is waste of money. I have tried.

Really bad product, create steaks in the windshield, still create fog in the windshield.

Not useful

Funciona bastante bien, lo volvería aComprar

Works really well, the item instructions are perfect.I have used them for a mirror in the shower so that I can shave in there. Whilst the water can attach to the mirror and make it difficult to see, moving the shower head allows the water to drain off and the anti fog cleaner does it's job allowing me to see my face whilst shaving.Have found it is also very nice for brushing my teeth in the shower as well

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。

good product

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!
