Prestone PSCW0029A Winter Screenwash, 5 Litre

Product Information

Eco Refill doesn’t compromise on cleaning performance. This is the same Prestone screen wash you’re used to, but now in a super-concentrated formula. Tough on dirt, streaks and grime, it’ll make light work of whatever winter sends your way.

The bottle of Wynns is the smallest here, yet it claims to be ‘Super Concentrated’ and offer protection down to -70C. In reality though, that headline figure of -70C is only if you use the Wynns neat, which is unlikely to be necessary in the UK. Screen wash is an essential fluid that’s used to clean windscreens and, on some cars, rear windows. Having screen wash in your car is a legal requirement; you’ll fail your MOT without it.

How do I use Prestone Screen Wash?

Powering through dirt, grime, and smears, Prestone Extreme Performance Screen Wash is the only product you’ll ever need to keep your windscreen clean and clear. In summer this makes it seem good value compared to some ready-mix rivals, but the advantage disappears in winter. It’s a legal requirement– that’s right, you could receive a fixed penalty notice if the police pull you over and discover you have no screen wash, especially when there’s reason to believe that reduced visibility has caused you to drive dangerously. Prestone lab tests simulate seasonal driving experiences, but real life tests are conducted on the road in extreme conditions. Prestone works in any weather to keep your windscreen clean for safer driving.”

As well as testing and our experience of using multiple screen washes, we also based our recommendations on the latest research and a number of factors. Some of the factors that we took into consideration included the formula’s type, seasonal use, freezing point, effectiveness and value for money. ConclusionWe tried it at the suggested level for protection down to -22C and it was fine and fluid after several hours in the freezer, but at that mix ratio it would make little more than half a litre. In fact, the instructions only suggest diluting it by up to a factor of 3:1, which means one bottle would only make a litre of fluid. Since the average washer reservoir is three to four litres, that’s going to be expensive. It certainly seems to make financial sense if you do. There are usually two types on offer; ready mix or the concentrate. We tried both, but the results were almost identical so we’ve concentrated on the concentrate.

Perhaps the most obvious reason to avoid household cleaners is the amount of foam they produce which, when applied to a windscreen, could lead to reduced visibility. Myth 4: Ready-to-use is a rip off That means total clarity and 100% visibility, as well as zero chance for dangerous sun dazzle to interfere with your view of the road.We’ve dialled up the concentration level of our Eco Refill Winter Screen Wash, with a 500ml bottle capable of making up to 5 litres of screen wash. That means you can keep and use the same 5l bottle, topping it up with Eco Refill and water as and when you need to replenish your screen wash. As well as removing deposits and dirt fast, Prestone Extreme Performance Screen Wash also dries clear thanks to our new and improved streak-free formula. Tested both in the lab and on the road, our flagship screen wash offers guaranteed visibility in all driving conditions – bringing confidence and clarity to every journey. Safe winter driving starts with maximum visibility. That’s why Eco Refill guarantees a streak-free finish, helping to combat hazardous sun dazzle and glare. Don’t compromise on results – trust Prestone to keep your windscreen clean and clear all winter long. As we knew our freezer was measured at 18C, we mixed at a ratio of 1.5:1 which should have given us protection down to 19.5C. However, although there was some liquid evident in the syringe it was too frozen to squirt until it had been out of the freezer for a few minutes. Tesco Concentrated Screen Wash (& Tesco Ready To Use)

Fill until the reservoir is completely full. You may need to wait for some bubbles to subside before you continue pouring, depending on the product you’re using. Normally, the hose leading to the reservoir is semi-transparent, so you should have an idea of when it’s nearly full. And you’re done! Developed to the same high performance standards you’ve come to expect from Prestone, Eco Refill Winter Screen Wash can also help you to reduce plastic waste. Thanks to its concentrated formula, just one small bottle of 500ml Prestone Eco Refill makes 5 litres of winter-ready screen wash – that’s a whole standard-sized bottle of screen wash for a fraction of the plastic. Day to day, you’ll know that your windscreen is being kept free from dirt, which will improve your visibility and protect it from the damage that deposits can do. Removing tough, dried-on dirt with ease, it’s the ideal year-round screen wash – ensuring maximum, all-round visibility from season to season.

Now that we’ve cleared things up and busted the myths of screen wash, it’s time to get serious and talk about why it’s so important. There are five very good reasons you should use high-quality screen wash, including: Unless your classic is very old, you’ll need to make sure there is some fluid available when you press the button to wash the windscreen. In winter it will help get rid of road grime and salt, in summer it helps clear fly splats, dust and diesel film.
