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.

Rain-X is a great product this stuff is nice because it more or less turns whatever windshield wiper fluid you have into Rain-X wiper fluid

Clean windshield

In rain the water sheers off so if you are going fast enough you don't need to use your wipers. The water just beads off.

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!

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).
