Di mot use this stuff if you have a car equipped with low washer fluid sensor . I put in the reservoir and 24 hours later low washer fluid light is on! Now need to clean the whole system. There was actually class action lawsuit.
Product is great
Works good and easy to use. Definitely helps during that misty rain and hard rain.
IT'S A VERY GOOD PRODUCT
I love Rain X but I’ve never been good at keeping up with regular applications. When I first saw the wiper fluid additive, I was a little skeptical that it would work as well as the directly applied version. However I was pleasantly surprised by how well the additive works. When my wiper fluid is low, I pour half a bottle (per the instructions) into the well and fill the remainder with water. My windshield stays “Rain X’d” all the time with no need to continually apply stuff to it by hand. It’s great. Highly recommend.
THIS IS THE BEST WINSHIELD WASHING FLUID !
Just add to tank reservoir, super easy.
keeps water and spots off and easy to clean
I live in FL so we get a lot of rain and I unfortunately do a lot of highway driving. I HATE driving without rainX on my windshield. The difference it makes is amazing. It’s so much easier to see especially when u get those white out rain storms. It’s gotten to the point I always keep it in stock in the house and I dnt feel safe driving without it when it’s rainy season. Would HIGHLY HIGHLY recommend.
Provides improve visibility when raining and so easy to use.
Cheaper in the long run than buying washer fluid by the gallon
Smears and streaking as wiper blades work
It did absolutely nothing for adding to my washer fluid.
NOT AS GOOD AS THE STUFF AT THE STORE. THIS MUST BE WATERED DOWN.
I read instructions and added it
A great additive for windshield washer fluid. I have used Rain X products for over 40 years. Driving in rain on the highway can be extremely hazardous, but Rain X products reduce the risk to a minimum. Apply their products as directed and you will be amazed.
THIS WORKS JUST AS GOOD AS THE ORIGINAL AND YOU DONT HAVE TO RUB IT ON THE WINDSHIELD
Love this product! Water beads up and rolls right off!
Rain just slides off window.Amazing
It works just not as good as the one that applies to the windshield itself.
This wiper leaves streaks, smears, and swipes all over my windshield. I can't see anything when it's raining. The only reason I gave it 2 stars instead of 1 is because I'm in a really good mood overall today.
Excellent product.. Awesome just dilute with water..works like magic
my go to windshield add-on for over 20 years, highly recommended.
100% a must have if your windows get wet.
Works well .I have used it before .Shipped fast.
Cheaper and bigger then what you get at the local auto parts, could just buy a gallon of water or distilled and put the 4oz in it and pour in like I was told to do, but I was out and just used 4oz and tap water for now and cleans the window and replace water like it should
The kind I
For some reason this stuff just made my windshield worse. Like it made streaks and when the sun was out it was hard to even see. Didn't notice it bead up the rain at all. I got the rainx windshield wiper fluid and that works way better.
I love water wicking products that work.It's almost pleasurable to drive in the rain.That's not what this product is.I followed all the directions and the product coated my windshield with an almost wax like layer that is impossible to see through.Very dangerous to drive with.After several days of dry weather after first use the window has large waxy areas that obstruct the most important part of the window.Very unhappy with this product.Cannot recommend.
Works as advertised. Thank you Shell Oil Co for a great product!
While I love the original Rain-X that you apply directly to the glass, this product is horrible.My wife bought this and used it in her brand new 2021. It left a oily white residue everywhere-- the windshield, the paint, everywhere.I ended up buying a $20 pump to remove it from her windshield washer reservoir.Don't try and shortcut with this product. Just use the original.
Add as much or as little as you'd like
i love to watch the water roll off.
Great stuff for the price! Beads rain off very well!
Water just runs off now don't even need the wipers when moving.
