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.
Excellent price
This simple additive will transform your driving experience in wet weather.Here in South Louisiana we experience frequent heavy downpours and this product greatly enhances visibility while driving in wet weather.
This stuff really works and incredible value
Water beads up and flows off windshield.
a good product if you like to have a concentrate rather than full gallons of windshield washer fluid.
If you live in and area that doesn't freeze, this stuff is the very best, AND most economical.
I have used this product for many years. One of the best products available on the market.
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!!!
I love everything about this product.
great product
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.
Absolutely love Rain-X products for my vehicle!
This stuff is amazing. Rex amazingly. Check out their lineup shower treatments, too
When you're driving 70,000 lb visibility is crucial. I wouldn't roll without this product.
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.
Works great and inexpensive.
Works like magic
good
I like it so far
I had my windshield wiper break during a rainstorm and I realized I was actually better off just letting it beat off the stuff works so well
Thank
I have been using this product for years and it's kind of hard to find nowadays because of the pandemic for some reason. So I picked up a couple of these bottles from Amazon. Works great.
Worked well!
I use this in every bottle of car washer fluid and even show people why and now they ask where I get it and I tell them.
works fine
A+ Highly Recommend
Water beaded up but tended to smear when wipers on
Added this to my window wash, seems as though I had to use more for it to bead on the glass.
only thing I dislike was shipping took more than a week but product works
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.
USED FOR SAVING MY WIPERS
It's not as good as the spray and wipe firm, but it does help bead the water up on the windshield.
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).
used produce on windshield and glass on all doors. Rain water rolls off windows for great visibility.
On the windows for car
This, with some windshield washer concentrate, water and IPA, makes a better and cheaper windshield washer fluid than buying at retail.
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.
easy to use, just pour in does streak a little at first, run your wipers for a few minutes with the additive to buff off the hazing
THIS IS THE BEST WINSHIELD WASHING FLUID !
Just add to tank reservoir, super easy.
Helps with Fog and Clarity in the rain!
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.
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.
