Prestone Screenwash Concentrate 2.5L, Screen Wash For Cars - Winter, High Performance Cleaning With Streak Free Formula, Extreme Performance Super Concentrated Screenwash, Reduce Plastic, 2.5 Litre

Poured this into the van and suddenly the windscreen looked like it had been polished by angels. Cuts through bugs, grime, winter muck — basically anything that’s tried to ruin your visibility since 2012. The concentrate is strong too. One splash in the tank and the washer jets started acting like they’d had a promotion. Smells decent, works fast, and makes your wipers look competent for once. Perfect for winter, summer, and every British season in between (all of which apparently happen in the same day).

I bought this after my washer nozzles and tubes got clogged up, necessitating a (paid for) trip to the dealership to get them flushed out. One possible cause had apparently been the cheap supermarket concentrate that I had previously been using (or concentrateS, as I had been mixing fluids, buying whatever was on offer at the relevant time). So after doing some research, I plumped for this specialist screenwash, and so far it has worked perfectly and no clogging of nozzles and tubes so far.

Super-Concentrated Winter Screenwash for Streak-Free Windscreens Prestone Screenwash Concentrate is highly effective at cleaning windscreens and removing stubborn dirt in all weather conditions. It works well in extreme cold, melting ice down to -18°C, and provides a streak-free finish for clear visibility. The super-concentrated formula can be diluted according to the season, making it versatile and economical. Easy to use and eco-friendly, this 2.5L bottle produces up to 50L of ready-to-use screenwash.

Best & most effective screen wash I've used & it's used all year round.

Superb for the money I would buy again

Best screen wash on the market, I make 15 litres out of one 2.5 litre bottle and use this dilution all year around... never freezes and always cleans the screen perfectly in both summer and winter, far better and far cheaper than the ready mixed products 👍

It's a good screenwash for all year except Winter. At -3°C it will stop working, or it will freeze on your windshield instantly.But it's cheap so lovely for the summer and worm weather, but if you looking for something to keep you safe in a below Zero, look at specialist winter screenwash.

Great product. De iced my windscreen in minutes. Only downside is it was hard to pour. Would have been better if there was a funnel attached.
