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.

Must have in Florida

December 22, 2022

This is an absolute must have for anyone living in Florida or other rainy areas. Mixing some with regular windshield washer fluid or even just water ensures your windshield stays treated and its much easy to safely drive in those summer storms.

Lasts All Season

Seems to work fine, beats having to spray the windshield every two weeks or so!

November 16, 2022

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.

Worked like a charm

October 19, 2022

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.

Love it

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.

Works For Me

August 21, 2022

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. I made sure to follow the instructions as to not add too much of the product and haven’t had any issues the past few months I’ve been using it.
