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

This Rain-X concentrated screenwash has turned out to be a smart upgrade for keeping the windscreen clean and clear in all kinds of weather. Once diluted as directed, it gives a streak-free finish that really helps with visibility in rain and spray, and the rain-repellent formula makes water bead and run off the screen much more easily. That’s especially noticeable at higher speeds on wet roads when visibility matters most. The fact that it protects down to around -15 °C is a big plus through the colder months, so I haven’t had to worry about freezing even on early morning drives. It mixes well with water, and a 5-litre container goes a long way, which feels good value compared with filling up ready-mixed bottles all the time. It’s not the cheapest concentrate available, but the performance really justifies it. If you want cleaner glass, better repellent action, and less wiping effort during poor weather, this product does exactly what it promises.

Excellent screenwriter. Clears away dirt easily and after a few uses the rain rolls right off the screen. However it has doubled in price since my last order, so I cannot justify buying it until it returns to its usual price.

Creates a slight film on the screen, which helps water bead off (but don't expect miracles). With this stuff, at 50+ mph I don't have to use my wipers in moderate rain. Smells alright too, not as chemical as some other products on the market.

I’ve tried a few different screenwashes over the years, but this Rain-X concentrate is definitely one of the better ones. It actually cuts through dirt and road grime properly instead of just smearing it around. The rain-repellent effect is noticeable too – once the wipers pass over the glass, the water beads off much more quickly, especially in heavy rain. I’ve used it in colder weather and it’s held up fine. No freezing issues so far, and it mixes easily in the reservoir without any strong chemical smell. Visibility is always spot on afterwards which is exactly what you want in winter. For the price, you get something that actually performs better than the generic brands. I’d happily buy it again as its great value, it's really effective at keeping the windscreen clear and the repellent effect genuinely makes driving in rain a bit easier. It also doesn't freeze even in the deepest of Scottish winter.

This is the second winter I’ve been using this product (neat), and it works perfectly. It doesn’t freeze (tested until -8°C) and keeps the windshield water-repellent, improving visibility.

A great product and worked well for £10.99 but went to order again and it is now over double the price. Shocking behaviour and not worth it for what it is.

Causes wiper judder

This screen wash is brilliant. The water beads on the windscreen and it is streak free. Good value for money.
