Rain-X RX11806D Washer Fluid Additive-16.9 fl. oz, 500. ml

The Rain-X RX11806D Washer Fluid Additive delivers exactly what you'd expect from the brand—reliable water-beading performance and enhanced windshield clarity.At 16.9 fl. oz. (500 ml), it offers a generous amount for multiple uses, and the price-to-performance ratio is excellent. Mixed with regular washer fluid, it noticeably improves how water rolls off the windshield, especially during light rain or misty conditions.If you're looking for an easy, affordable way to boost your washer fluid’s effectiveness, this is a smart, high-value add-on. Very satisfied.

I usually but this stuff by the gallon, literally , but wanted to try out the concentrate to see if it works better . I paid $6.25 for the concentrate here and 4.50 for a gallon of the blue washer fluid . That's about $6 per gallon when it's all said and done . A gallon of the pre mix where I buy it is $7 regular price .That being said economically which ever one works better will be a wash and pre mixed will be slightly easier to use .Without knowing the long term difference I'm giving it 5 stars for the measuring slots on the bottle , small and easy to use tip and ergonomics of the bottle itself . Between the 3 it's easy to get the correct amount into the reservoir without spilling any.The pre mix doesn't streak my windshield at all but works great for about a month then I just do a quick wash squirt and it's protected again .The concentrate should work the same way .I'll edit this review if it doesn't .I'm using this stuff on a 25 Kona work solar glass.

I was looking to brew my own windshield wiper fluid and wanted an additive to help assist water droplets and this seemed ideal for the cost. Haven't had too much rain but this seems to really help with the light amount that has come by.

Rain-X washer fluid really works wonders on rainy days. It not only cleans dirt and grime but also helps repel water, improving visibility while driving. I noticed that water beads up and rolls off quickly, making windshield wipers more effective. The scent is mild and not overpowering. It’s easy to pour and works well even in colder weather.

This product DOES WORKS wonderfully...

First time getting this vs. the usual premixed ran-x product and it was a success. At least here in the SC spring/summer. Water beaded better than any premix I have had in my truck and it was able to clear off moderate road grime and bugs.It was on sale when I bought it so was a solid value proposition also (makes 4 gallons I believe).

Been using this stuff since 1990, helps water bead off windshield, and makes your wiper last longer

Product works to some minor extent… I recommend doubling the amount stated in instructions if you want water to bead. Will leave a residue on your windshield any place your wipers do not touch. 3 star for ease of use and lack of result as stated in description. Would recommend getting the spray bottle and hand cleaning windshield then applying rain x original from the spray bottle instead of this
