Rain-X AF21106D Glass Cleaner

This will save your head!

This stuff is magic, I use it on my bathroom mirror and there is no fog after showers, and I have no vent fan in my bathroom. It lasts a few weeks before needing to reapply. You have to use a generous amount, it does leave some very faint streaks that are not visible unless you’re looking, but I tried using less once not to have those and it didn’t work.

Rain-X for the outside windshield is a superior product and I'm a faithful customer. This product from them is not that great. It can prevent fog, but it creates a film that comes back, and you can see it during daytime driving. You have to make sure you apply it correctly but even then, you will need to address the film that builds up after a week or so.

Very well-made.. nice quality... Great gift!

I put this product on the inside of my vehicle's windshield to keep it from fogging up so much. Not only does it not work, the defroster won't take the fog off. I have to carry a towel in my vehicle and wipe the windshield because I go anywhere. I'm hoping vinegar and dawn will remove it or I may have to get a new windshield.

I applied this product at front window in my car. I think it worked well at first. It was obvious that front window didn’t get fog but rear window got fog. However, front window got foggy again. Is it because I wiped the window with dry cloth later? I don’t know. I assume I need to apply this cleaner often after I wipe the window every time?

Great

I always loved this product it does what it says on bottle
