Followed the directions for the additive to a full Reservoir of wiper fluid. Noticed streaking under the lights at night, other than that it’s a good product.

Concentrated RainX that works with regular windshield washer fluid

October 26, 2021

The whole family loves RainX, and this makes for easy use if you forget to ask the shop not to top off the fluid in the car.It works even if the first time you use it is during a rain storm. VERY helpful with visibility while driving during inclement weather (please still drive carefully).

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.

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.
