Rain-X Concentrated Screenwash with Rain Repellent - Superior Visibility & Protection for All Seasons - Prevents Freezing Down to -15°C - Streak-Free & Water-Repellent Formula - 5L[Amazon-developed Certification] Compact by Design

Bought this based on the reviews and have not been disappointed. It suddenly rained hard for a few minutes whilst I was on the motorway and I didn't have to use my wipers as the rain just bobbled and ran straight off the windscreen with no loss in visibility. It didn't freeze in the recent cold weather (-8°c) and it cleans to a crystal clear finish.I am very happy with it. It is currently not diluted due to being winter but the bottle has clear and easy to understand instructions for how to use it throughout the different seasons. I certainly won't be returning to the cheap stuff I used to get.

I've been using Rain-X screenwash for a while now, and it consistently impresses me. It leaves my windshield crystal clear, even in heavy rain and grime-filled winter weather. The water-repelling technology makes a noticeable difference—rain just beads up and rolls away, improving visibility and making driving safer.I also appreciate that it works well without leaving streaks, which was an issue with my old screenwash. It's easy to pour, has a pleasant (not overwhelming) scent, and the performance is excellent overall. Highly recommended for anyone looking to make driving in wet weather a bit easier!

Great screenwash to use. I usually mix about 1:3 or 1:4 and it does the job well. It's not a miracle worker though, as if you try to use it on a dirty windscreen it'll fall flat. Great if it's been cleaned and waxed. Cleans better than the Prestone I used to use but is a bit pricey. Only reason I've given it 4 instead of 5 stars is the price. While it's better than any others I've used, it's not 4 times better. Good enough that it's now my regular

Great screen wash, no streaks and keeps the rain flow consistent. Does not wear out as much as you expect after spraying and wipers used

Great value concentrated screenwash, can really notice the rain repellance.

It has fairly good hydrophobic properties (i.e. the rain does run off quite well) but it's actual cleaning ability is not that great - I prefer a windscreen wash that gets the bugs and grime off.

arrived on time - seems to be a good product

I buy this all the time it's brilliant but you have to put it in to the correct strength, the rain literally runs off the screen and you hardly have to turn your wipers on, it also makes it easier to clean the bug's off the screen they don't seem to stick on so hard.
