Rain-XRX11806D Washer Fluid Additive-16.9 fl. oz, 500. ml

The best. Way easier then hand applying Rain-X to your windshield and works almost as well. I used to be able to find this item at any Walmart and other stores also, but in recent time stores are no longer carrying it. I hope Amazon keeps it in stock because it's the only place I can seem to find it these days!

I tried this additive in hopes it might improve the effectiveness of my wipers at keeping my windshield clear. This product works IF USED IN THE CORRECT QUANTITY. This product is concentrated and must be diluted to 4 ounces per gallon of windshield washer fluid. (I happen to know that my truck can hold roughly half a gallon, so I just eye balled about 1/8 of the bottle.). I found that this product does initially cause a haze where it has been applied, but after about 5 seconds it's completely invisible, with no residue. I tried with a hose and it made a significant difference in how water rolls off of my windshield. (this product is designed to cause the water to bead up making the wipers and wind more effective at removing the water. It's worth noting that I used this product with RainX windshield fluid (the orange one) so I am not sure if their is any chemical interactions that may occur with other washer fluids.

does the job and convenient mixing

As always you can never go wrong with Rain-X products. I ordered one of these here because all the stores locally where out. The cost was a lot more here but I guess they get you on supply and demand. American Capitalism at its best...lol. I am rating the, Rain-X additive only at 5 stars because this stuff has worked great for me for many years. Sometimes I do not even have to turn on my wiper blades as the water beads and rolls off of my windows.

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.

I love this product. Way easier than doing it with a rag and waiting with their other products. Add to washer dispenser in car and it does the work for you. Water just beads and moves off the windshield. Great product.

Better than buying it gallon jugs. This works just like the premixed. Only draw back is, if you live in a colder climate, you'll have to add the dicing chemical in it.

Premixed works better for me. I mixed this with distilled water to ensure no residue, but the coating of premixed solution is not there. Price and mixing of filtered or distilled water to dilute does add much to the cost of using concentrate but when washer fluid in your car runs out, ease of use and cleaning power of premix seems better.
