It makes the rain bead off when it rain. Can't live without it. So much easier than cleaning the windows with the original Rain-X.

5.0 out of 5 starsWorks great, and the bottle will last quite a while.

September 27, 2023

I had RainX wiper blades on my old car, and know the RainX products work great keeping the windshield clean and clear. Having just purchased a new vehicle, I didn't want to replace the blades or try applying the spray polish. I added 4oz. of this additive product to my already fairly full reservoir, and it works great. This is not the method advised on the bottle, but I'm happy with the results and the bottle will likely last me a full year.

35 years best product I've used.

September 10, 2023

This is a great product, I've used Rain-X in one form or another for 35 years. Every new car I've bought I made sure to treat the windshield as soon as possible. These days, that's as easy as pouring this in the washer jug under the hood. Really helps water fly off the windscreen.

5.0 out of 5 starsSuch an upgrade!

August 28, 2023

Okay to be fair I replaced windshield wipers and also made my own wiper fluid with this + some washer fluid tablets, but it's night and day. My windshield stays cleaner for longer, no streaks, and the water beads up when I clean it like there's a barrier of some sort that's helping make it more waterproof.

Put more than the recommended dosage in your reservoir, but it does as it's supposed to do and I recommend it more than the original or spray, so you don't have to keep spraying and wiping it on so often.

Good, but not as good as regular Rain-X

January 25, 2023

It does a little repel on the windscreen. I’ve mixed it with plain distilled water and right amount of Rain-X windshield washer fluid additive. I’ll just stick with Gyeon view Q2 that one works the best and last longer.

At first, I couldn't believe this would work as an additive, no more that they recommend using, but so far, it has performed great.Yes I did apply a base coat to my windshield, per instructions.For the last month my windshield has beaded up and worked fine.I heartily recommend this product.

Works fine for me.

November 14, 2022

I did read some complaints that this stuff can leave smears and stuff and worried about that, but due to financial concerns thought this would be far more efficient than buying Rain-X spray over and over so decided to take a risk and try it.My own results have been pretty good.I don't see any smearing or anything like that.It basically Just Works(tm).One thing of note is that it is supposed to be measured and the correct amount put in depending on how much water it's being mixed in.I suspect that many who have seen streaks and such may have put in too much.Most cars don't hold anywhere near to a gallon, but the instructions for measuring are meant for one gallon, so you have to divide appropriately.Much easier is just to take a gallon jug, fill it with a cleaner or distilled water and then just mix that way so you don't have to do any math or careful measuring and have more of the cleaner for later besides.Use up whatever is in the car, and then just pour the new mixture in.I have also mixed this into a small spray bottle with an appropriately smaller amount mixed in and it seems to work ok.This effectively gives me a Rain-X spray at a far lower cost.It is less effective this way than the real spray, but it seems to get the job done fairly well all the same.

I added about half of what is recommended to what was left in my windshield fluid reservoir from last oil change at dealership topped off with a cheap bottle of Rain-X wiper fluid “Bug Remover” for $2.98.It works just as well as a $50 rain-x treatment and it looks like the wiper fluid and this will last me 3 oil changes…maybe 4.

Great stuff

October 18, 2022

I've been buying this stuff for many, many years. It is a great additive and so much easier to use (add to your windshield wiping fluid), compared to the older method of spraying it on your clean windshield then buffing it in.Very effective, and if you drive in the rain often-- you will understand and appreciate the before and after. It is a night and day difference.

effectively keeps water and dust away from windshield

October 02, 2022

keeps water away from windshield, rain does not accumulate and wipers remove it quickly. improves wipers ability to clean dust etc. with a few strokes + washer spray. also can be used directly on windshield, but better dilute first.

September 07, 2022

Ok, initially I used this with the RainX Wiper fluid asI always do and was suggested as okay to do so. HOWEVER, half a mile down the road, I had to pull over - I COULDN'T SEE!! Please dilute the suggested quantity with at least a 16oz bottle of water...even with the wiper fluid All Season PreMix. I love the clarity of the mixes.

Just buy it! So much safer with this on my windows!

August 22, 2022

I always wondered why people seemingly forgot how to drive in the rain... It's because they don't have rainX on their windows!! I hardly have to use my windshield wipers when I have this in my dispenser. I like how this is a concentrate so you can just mix it with regular water.

I was nervous to buy it because some of the reviews but for the price, I figured why not. I must say… I have no regrets. It worked perfect for me. No streaks or anything.
