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

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.

Love this stuff. Much easier than applying directly to windshield and works just as good

I have been using Rain-X for over 20 years. Although, like everything, the price has gone up, it is still worth the cost. I learned a long time ago to mix 2 ounces per gallon of windshield washer fluid. It doubles the amount of time that the Rain-X will last and I have personally not seen any difference it the performance of the product from light mist to outright downpour. Water literally beads up and is blown away by the air as your car goes down the road.

This is a more hands off approach to the issue and I feel it works well for its intended purpose. It is however not as good as the dedicated rainmax ones that you apply it and rub it off and such and hence the 4 stars. I did not experience streaking or other issues that people mentioned as I measured precisely as described but it is possible that if you put a little more then you would get some staining and such. I recommend doing a little less than the recommended amount and test it out for a couple of days prior to doing the full amount.I would buy it again as it is just easy to use in my opinion.

“Rain-X is a game changer for driving in the rain. After applying it, water beads up instantly and rolls off the windshield, giving you a much clearer view. It really improves visibility during heavy rain and even helps reduce ice and frost build-up in colder weather. Easy to apply, long-lasting, and definitely worth it for safer driving.”

I tried this additive in hopes it might improve the effectiveness of my wipers at keeping my windshield clear. This product works IF USED IN THE CORRECT QUANTITY. This product is concentrated and must be diluted to 4 ounces per gallon of windshield washer fluid. (I happen to know that my truck can hold roughly half a gallon, so I just eye balled about 1/8 of the bottle.). I found that this product does initially cause a haze where it has been applied, but after about 5 seconds it's completely invisible, with no residue. I tried with a hose and it made a significant difference in how water rolls off of my windshield. (this product is designed to cause the water to bead up making the wipers and wind more effective at removing the water. It's worth noting that I used this product with RainX windshield fluid (the orange one) so I am not sure if their is any chemical interactions that may occur with other washer fluids.

Great additive for your washer fluid.

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
