Rain-X Concentrated Screenwash with Rain Repellent - Down to -15°C - 5L

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.

I’ve used this Rain-X screenwash for years, and it’s the only one I buy now. I find it effective at cleaning the windscreen and good value for money. It’s easy to use—just follow the instructions for the correct dilution. It’s been a reliable choice for me, and I’m happy to keep using it.

Sometimes leaves streaks. Expensive compared to similar products, used to love this product but I find Prestone winter screenwash is better for me - cleans just as well, half the price, doesn’t leave smears but also isn’t rain repellant. Find I have to reapply fairly frequently to maintain the rain repellent factor which results in using more of the product.

Have always like the other rain-x products and this is no exception. I little pricey for screenwash but it did prove itself through the winter and the coating is still working wonders on the windscreen. I would recommend you use up all the other screen wash before adding this to your car to get the full effect.

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.

Works great

I use Rain-X on my car so I use this to top up the finish when cleaning the windscreen whilst driving. It works very well and doesn't deteriorate the water repellency, unlike other screenwash brands, therefore the finish lasts longer. Easy to use and 5L lasts months (depending on individual usage). This won't apply a water repellent layer to your windscreen, for that you need the actual Rain-X spray or bottle and apply it as per the instructions. However this does top it up once applied.

If you like a clean windscreen where the rain just repels of while driving this is the screen wash for you, you can drive on motorways with out having your wipers constantly going, it’s easy to just fill up your washers with this and water mix it’s always a little more expensive than you regular screen wash, but if you want to be scientific about it using your wipers less give your car less drag and will save a microscopic amount of fuel.
