Rain-X Anti-Fog, 3.5oz Bottle - AF21106DW

Love IT, this stuff works it's not a 100% but really stops your windows from fogging up so you can continue to see out your windows while using your car. Simply clean your windows like normal and apply with cotton cloth is best. a little goes a long ways.

This stuff works great , if you have not tried it, do so , it'll only take one time and you will use it for life on all your vehicles!

i absolutely love this helps keep the windows from fogging up only have to re apply every 1-2 weeks depending on how cold it is outside

I'm very pleased with how small the amount was that I had to use and it stopped the fog 100%!! It isn't a defogger, it prevented the fog. Exactly what I needed.

It gets rid of fog but in the beginning thats a lot what you have. For some reason when you first put it on, you get what it supposed to eliminate. In time, it is wonderful but the first few days it is not exceptional. I would still buy it, though.

This item works well on windshields, the glass looks awesome, I approve of this because there's no film nor streaks which is the ultimate goal.

Used once then the rest leaked out of the top even while closed. Rain-X really needs to redesign these bottles so that they're leak proof! All of their products in these bottles leak if they're not sitting upright at all times, even before opening them! Make sure you don't put it in a bag with any other items when purchased in store either! It will get all over everything every single time guaranteed.

This product is just okay. It takes awhile to apply, it leaves clouding and blurriness on the mirror if you don't buff it off of the mirror just right. It works well at keeping the mirror free from fogginess after a shower, but that only lasts for a few days before it wears off. This product may work better in a less humid environment, but I don't think that it is worth the effort and the money.

use this product a couple years ago worked great bought it again in 2025 cannot get rid of the smudges they must have changed something in the product it was amazing before

I thought it ruined my 5 foot wide mirror leaving massive streaks behind. I had to wash the streaks out, after a small panic. It did still "work" but that included streams of water coming down the mirror. If you do use it, keep it to a small area that you'd want to use in the event of the fog coming on.
