Sensor failed

October 08, 2021

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.

This, with some windshield washer concentrate, water and IPA, makes a better and cheaper windshield washer fluid than buying at retail.

Very effective with no work

October 01, 2021

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.

Must have!

September 03, 2021

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.

A Great add-on for already treated Windows.

I LOVE RAIN X

July 11, 2021

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.

Streaks, Smears, Swipes.

May 27, 2021

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.

Go with the wiper fluid, not this

March 26, 2021

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.

WARNING DANGEROUS

March 25, 2021

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.

I love Rain-X, but not this

March 21, 2021

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.
