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

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.

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).

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.

I think this performs better than premium brands in the UK. Removes muck from screen well and appears to have a better antifreeze ability than autoglym

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

By far the best winter screen wash. Never freezes in winter when used neat or diluted according to the instructions. Very little smearing in use. If your wiper blades are in good condition. Overall good value for money.

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.

Nice scent, mixes well and cleans great. No smears or streaks. Sprays clear. No issues with freezing when used as per instructions. Seems great quality for price.
