Used it in a big repellent washer fluid and works perfectly
After using the RainX applique on all windows of the vehicle, the coating has washed away months later. The windshield however has retained the water resistance effect and that is while only using the washer fluid a few times over the several months since adding to the reservoir.
This product is wonderful. Mixes easy and my windows look great after each use. Recommend this product and will by again.
Working good. Keeps window cleaner
Just put it in your washer fluid and it works just fine.
I put like three different forms of this stuff on my car, it just works. I know there's a lot of people that say it doesn't work and leaves streaks, but pleassssseee hear me out. Their products have so much potential and are underrated. I put this $&@# on my windshield and it leaves opaque streaks!?! -First grab some old newspaper and windex. Clean the windshield until it's undoubtedly clean. -Now grab your regular strength rain-x and apply generously. You will know if it was properly applied if you see an opaque film. If you do not see a definite enough opaque film, you need to reapply a second time (after elbow greasing the existing opaque streaks out) Do not use any more wet products to clean after your complete starting clean on your windshield. Remember to always do one extensive cleaning first before your project. -After applied properly you will see slightly opaque streaks throughout the entire windshield. The more consistent the film color is, the better it is applied. You con continue to even it out and keep applying as long as you use a dry rag to remove the existing film. Once you are satisfied with the amount of product used, grab a clean side of another rag and remove all film until it is completely transparent. -You will know if it is properly applied when you use your wipers with water on the windshield if for a split second after the wipers go over, you see hints of opaque reappearing behind the wipers. At this point add your windshield wiper concentrate to have your coat reapplied as you use. (Use your wipers for 5 seconds once a week or so) Now the coat stays there, and lasts much longer. If your at this point and you still see streaks, you didn't clean your windshield extensively enough the first time. You can always go back and elbow grease everything out before trying again. These streaks are not permanent, it's what a proper coating looks like, which might take some getting used too. The best case scenario for this product is highway while it's raining. You will need to use your wipers so much less because the water will bead up together and fly off. This product makes you rely less on your wipers. Still use them, but you'll notice that your not struggling to see even in the heaviest rain because there's 60-80% more visibility because the water sticks to each other instead of the windshield (so most of it beads up together and slides down). It's not magic, water still is on your windshield it just changes the properties of the surface. Really just added safety to your car. And I'm all for safety and visibility on the road. That's why I recommend it, it takes the edge out of driving in the rain and is just more added safety. If you're going with rain-x, go with both! I would not recommend just going with one or the other, they really work together so much better. Even car washes use this stuff haha! You just get a lot more concentrated stuff here on amazon. One of my favorite brands ever, highly recommend! Elbow grease those streaks out until it's clear and you're going to love the results. Sincerely, A Rain-X Addict.
Works Great here in the PNW Rain. Bottle lasts me around a year. I use about 1/2 the bottle in the winter, and 1/4 for the other spring to fall top ups.
Works best during the winter time when its too cold out to do the original rain X and biff off. If you're constantly using your wipers to clean off salt and snow. Just spray and spray all done for a whole anything afterwards will just slide off
If you mix too thick or over use, you may end up with a white line, where your wipers stop, on your windshield. Thats just user error, but I’m sharing because I did it. But, this is great stuff.
It does what it claims.
The product was recommended to me and I love it!! Works perfect for what I needed.
Work truck was a pain to drive in rainy conditions. Followed instructions and visibility increased drastically. Coworker even asked if I waxed the windshield.
It works and good price.
Recommended: I noticed a difference. Rain did bead as it says. Overall it is worth the money.
Purchased because it will repel rain and it makes it a little easier to remove bug splatter off the windshield,purchased mainly for the wife’s vehicle as she travels 120 miles round trip 3 days a week for work and living in the south you always have rain a bugs
Good value
Works great good value for the money, put some in your washer tank and rain beads on your windshield
Rain slides right off. Don t have to use. Wipers as much.
I noticed after adding half of this to a bottle of washer fluid that the windshields ability to “which” water was much improved, makes it more slick and easier for water to fall off and not have to use the wipers
As if I bought from auto parts store
It was an easy and mess free pour :)
Love this stuff! It makes such a difference in rain moving off your windshield. In a light rain you don’t even need to use wipers if you are doing over 50mph.
I work construction and do a lot of highway driving to get to different jobs it's. I add this to washer fluid and when it starts to rain I just hit the washer and let the wipers go for a few seconds and at highway speed rain beads up and flies off windshield instantly. Most of the time wipers aren't even required. It works much better at higher speeds so people who mostly drive in the city probably wouldn't see the benefits as much.
Product works great
Works very well on my windshield.
This one bottle will last a long time. I dilute it per instructions. I also put some solution in a spray bottle and use it treat the other car windows. Water and rain just bead off the glass.
Adding a squirt of this to the last washer fluid refill (303 (230395) Products Automotive Instant washer tablets) has been the best wiper fluid I've ever had. It really creates a remarkable difference even during heavy rainfall.
Perfect solution.
Always good stuff.
Lots of bubbles in the mixture. I wish it had some color in it, otherwise the mixture looks like plain water.
It works as described
Good
Just add to your windshield washer fluid reservoir and you are set.
Works great
Good
Effective and inexpensive replacement for the premix rain-x
Haven’t noticed a lot of difference!
Keeps windows clean for a long time
Just what we ordered
Works as expected.
Working as intended.
Great stuff, mixed with regular washer fluid! Makes rain bead up on windows, easier to safely see.
I honestly did not know that Rain-X made a washer fluid additive. I recently came across something else new to me: Washer fluid tablets. You drop them into a gallon jug and fill it with water and bam! washer fluid. So I figured I'd look to see if this exists and it does. Now I'm making washer fluid for probably 1/10 the price and I don't have to apply the Rain-X separately. I didn't rate the "Easy to remove" part because why would I ever want to remove Rain-X from my windshield lol!
I added it to the washer reservoir & with new Rain-x Endurblades I enjoyed a streak free windshield. Don't know which was better, but I like both!
Good for in between applications of rainx windshield that you put on and polish off
always use this makes a big differrce when its raining
I recently tried the Rain-X Washer Fluid Additive, and I'm impressed! Not only does it effectively repel rain, snow, and sleet, but it also leaves my windshield crystal clear. The application is hassle-free, simply mix it with your washer fluid, and you're good to go. Even in heavy downpours, visibility remains excellent, providing added safety on the road. Plus, it's budget-friendly, offering great value for its performance. I highly recommend this product to anyone looking to enhance their driving experience, especially during inclement weather. Say goodbye to streaks and smudges, and hello to a clearer view with Rain-X Washer Fluid Additive!
lt does what it says. Add a small amount to a gallon of water and put it in the windshield compartment. Saves on money and so easy to use.
Easy to pour some in the washer tank. Spray it on windshield and its crystal clear. Will purchase again when needed.
Makes regular fluid into rainx fluid. Water beads on windshield and is easy to see thru in heavy rain
