It’s magic

June 08, 2022

I was skeptical.Every shower before I applied this product has resulted in a fogged bathroom mirror, even with the fan on.I applied this per the directions (twice, for good measure), and today the mirror was crystal clear.The mirrored light fixture was fogged, inside the medicine cabinet was fogged, but where I applied this product was clear.I have enough product leftover for a lifetime of re-applications if needed.I’m sure there are limitations to how much humidity there is before it will fog, but it worked great for me!

Hard not to use this stuff!

May 18, 2022

It absolutely drives me nuts when my windows get all fogged up, especially when there's streaks or marks it just makes them stand out even more. Visibility wise it's terrible, I've almost ran off the road before because the fog was conveniently placed where the road's edge was. I had tried this years ago because my stepdad had some in his auto supplies, he used it for his mobile home he had forever ago the windows were double paned and would fog terribly. After using it the first time I was amazed there was an actual "solution" to fogged glass, it really works wonders for minimum to moderate moisture. It starts to fail when it becomes really humid, but by then you should have turned on your AC defogger (I only left mine off to see how much it could handle). It holds up really well with just one coat and that tends to last for months with maybe a few touchups in the worst spots. I've been buying this product ever since and swear by it and have recommended it to anyone who has foggy windows. Also pairs great with Rain X Repellant when it rains and it's extra humid, just cuts right through all the moisture. I prefer being as safe as possible when driving and having this product helps with that goal. Also if you're a bit obsessive about keeping your car clean, this also is for you.

Works great!

April 10, 2022

I followed the instructions and it has saved me! You HAVE TO clean the windshield first. Then, apply this on. My A/C and defroster has issues switching between each other whenever I press either one. I have given up and just keep it on A/C so I worry at times whenever its cold. A fogged up windshield can be very dangerous and this has worked out really well for me! I’ll definitely be reapplying for next winter.

Seems to prevent or at least significantly reduce fog on the bathroom mirror

March 15, 2022

I was not too sure about this product, but I like to shave after taking a shower, by which time the mirror over the sink is all fogged up.So, I figured I'd give this a try.It has a very strong chemical odor when you spray it on the glass.Not sure the vapors are especially healthful.But I put it on just the lower half of the mirror - so I'd have a basis for comparison.It really did significantly reduce fogging, so that I could shave without having to wipe the mirror down first.Impressive enough that I reapplied it over the entire mirror.Easy to use and seems effective enough.Not sure how long it lasts yet, or how often it will need to be reapplied.

This product really fog/proofs your glass/mirrors, BUT it is NOT a cleaner. Do not expect your glass to get cleaner when you apply it. CLEAN the glass first with your favorite product and THEN apply this MAGICAL liquid.

Sort of works

January 19, 2022

I'm not sure yet if this product works. You know how every once in a while the weather conditions are perfect that you can't get your windows to defog? That's why I bought this product. I applied it and wiped it off per the directions. It left the windows hazy all the time! I had to wipe it several more times to get rid of the haziness. There hasn't been another "foggy window" day since then, so I don't know if it works. I hope so.

Hard to remove streaks, fogs up anyway

December 28, 2021

I’ve used this in the past and it used to be way better. It’s nearly impossible to apply this without getting some streaks. It goes on very cloudy and streaky and you have to keep rubbing it in and wiping for way too long to remove most of the streaks. And then it dogs up anyway. Pretty useless

Easy to use

December 10, 2021

The Rain-X Interior Glass Anti-Fog was easy to use. I just sprayed a little bit on a paper towel and did it section by section. Then when I was done, I wiped it over with a dry paper towel. After my first application of it, I noticed the next morning that my windshield wasn't foggy like it usually is in the mornings. I'm tempted to try this on my bathroom mirror also to prevent it from fogging up. I would make sure it's wiped down well because I ended up having streaks on my window that I didn't notice until the next day or so.

Helped Me See Better

December 05, 2021

Ever since I bought my vehicle I swear it seems like the defrost on the driver's side of my SUV doesn't work as well as it does on the rest of the vehicle's windows. This has always been annoying, especially living in a place that gets pretty cold in the fall and winter. I'm also young, my eyesight has never been the greatest, and I have to drive in the dark, early morning hours to get to work. This hasn't been a perfect product but enough of a relief for my fogged up windshield that I'm highly satisfied by the results. I can see alot better! I keep this on hand in my car all the time just in case, especially since it's wintertime.

Great on Glass

December 05, 2021

I have a tremendous amount of fog that builds up on the inside of my car. I went online looking for a solution for Spring and winter. The condensation from moisture usually builds up on the inside of the cars windshield. I came across (Rain-X's) Interior Glass Anti-Fog solution. I waited a few days for it to arrive. When it did I applied it to the inside of my cars (front) windshield. I waited over (1) month to make the review since there was a tremendous lack of moisture in our region. Or it was just doing its job wicking away the moisture, when I no longer noticed it. Well it turns out, the (Rain-X) Interior Glass Anti-Fog solution that came in a 12ox bottle was in fact doing its job and it was amazing an fantastic. It was so amazing for me that, i just had to make the review after not having any issues for over 1 month ! I would defiantly recommend this to anyone with the same (annoying) problem of foggy water on the windshield in the mornings. This is an exceptional time saver and will greatly help with getting, where you are going, much quicker.

Lifesaver

December 05, 2021

This product is pretty much a lifesaver. It is not completely without issue because it is difficult to get the windows completely streak-free even after cleaning the windows first, but it really does prevent my windows from fogging up. It also works on bathroom mirrors which makes it extra handy. All things considered including the price, I'd highly recommend it if you live somewhere that this is a constant issue for you.

No Fog

December 04, 2021

Rain-X Interior Glass Anti Fog it a good product. I used it for the interior front windows because you know, those windows fog up in the early morning. Especially now that it's getting colder. Directions are easy to follow. I used a microfiber cloth and sprayed some of the Rain-X onto it. Made sure I got a good cover and wipe down clean. Then next morning while taking the kids out to school, I didn't have to use my defrost much to help get rid of a bit fog a formed up. Much better than sitting in the truck for 10 minutes or so to wait for them to clear. I definitely recommend Rain-X Anti Fog if you want quick clear window early in the mornings.

Can't use on tinted windows

December 04, 2021

I was hopeful that this product would help with fog on the inside of my car windows, but when I noticed there wasn't a "safe for tinted windows" claim on the bottle, I contacted the manufacturer and they confirmed the product can't be used on tinted windows. So, I was not able to use this product as all of my windows (including windshield) are tinted. I hope this info helps someone else gauge if it's something they can use on their vehicle.

So Easy To Apply And Wipe

December 02, 2021

I love this stuff. It's so easy to apply and wipe. Doesn't smear and doesn't take much. Last for about a couple weeks. I'm in a rain/snow environment and have tried many things. Plus my vehicle sits underneath a tree. Not only does this deflect the tree sap to easily wash off, it makes the rain and snow just run down the window without spots.

A must for daily drivers

December 01, 2021

The Rain-X Interior Glass Anti-Fog is a must have product for daily drivers. I drive forty-five minutes one way to work each day with the sun in my face on the way to and from work. Without the Rain-X Interior Glass Anti-Fog this drive would be immeasurably more difficult. When I got a new vehicle in 2018 that has a cabin filter in it I noticed that the inside of my windshield would get a film on it that made it difficult to see when the sun was in my face. Since using this product on the inside of my windshield I have not had any problems with diminished visibility. I apply the product every two weeks for the best results. I have found that it not only helps with my visibility but also helps in the morning here in the North country lowering the amount of time I need to warm up my vehicle before driving because they would fog up on the inside when cold outside. This product really helps maintain optimal visibility in your vehicle in conditions that like foggy, humid, rainy or snowy weather where your defroster struggles to keep up. I would highly recommend this product to anyone.
