Easy to use and works well

It doesn't get any simpler to use. Just pour it in with your wiper fluid as directed. Easier to apply than the spray or wipes and it works as well.

Seems to work!

April 23, 2022

I didn't know it needed to be added to washer fluid first, so that was messy.I had purchased a new gallon of Rain-X bug washer fluid and this wouldn't just go in that gallon until I poured out a good amount.Just be aware you MUST MIX this in with washer fluid.SEEMS TO HELP though so I'll take it!!!

Love rainex

April 09, 2022

Due to me not pushing the wiper in until it clicked. We had a rain storm and my wiper just shot over my head on the highway. Wouldn’t have been able to go anywhere without the rainex on the windshield making it still easy to see.

Walmart or any auto store (autozone, o’reilleys) hasn’t carried this product for awhile. I’m thinking maybe since the pandemic and i still don’t see it. Now that it’s here. it’s made my life easier. I’m able to see clearer especially when it rains. no glare!

I have been using RainX products for number of years. Their windshield washer concentrate does a great job in causing water to bead up.Plus it cleans the windshield very well.

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.

Love Rain-x

August 29, 2021

Works just okay.Better than nothing but certainly not as good as traditional product being rubbed on the windshield.Certainly makes a treated window last longer.
