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.

For winter driving, we recommend a 50:50 mix of screen wash and water; this ensures maximum freeze protection. In summer, you can reduce the amount of screen wash you use; a 30:70 split is best. Whether melting ice on a cold winter’s morning or eliminating dried-on bug splats in the height of summer; Prestone Extreme Performance Screen Wash delivers powerful windscreen cleaning when you need it most. 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.It can also help you avoid wasting screen wash – if you mix it yourself you could make it too strong and end up needing to buy more, but on the other hand if you make it too weak it won’t have good enough cleaning abilities. Myth 5: Antifreeze in screen wash is like coolant/antifreeze Removing even the toughest deposits in a fraction of the time of standard screen washes, you’ll use less and save more when filling your car with Prestone Extreme Performance Screen Wash.

The first reason is that it freezes, which doesn’t bode well on frosty winter mornings. If water freezes in the wash reservoir or jets, it could cause lasting damage when you try and spray the screen wash, and this will cost you money to repair. 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 cleaning ability was adequate if not spectacular, clearing the oil but leaving a remnant of our glue. This means that the Tesco wash is good value, but you’ll need to use more of it to clean away screen grime and refill the reservoir more often. Prestone Max Visibility Screen Wash Get yourself some high-quality concentrated or ready-to-use screen wash. If using concentrated, make sure you use the correct ratio of water and screen wash for the season. You may also need a funnel to help with pouring depending on the type of bottle your chosen product comes in. Do you have a question about Prestone Screen Wash? Maybe you’re new to driving and want to know more about how screen wash works and how often you should use it? The Halfords wash gave the best cleaning performance and excellent freeze resistance at a reasonable price so takes the win here, but we’d recommend buying the ready mix rather than the concentrate as – bizarrely – it’s better value. Screen wash is available in a variety of colours including blue, yellow, green, and pink. It’s made from a mix of water, antifreeze (usually alcohol) and cleaning agents, which are added to help remove dirt and ensure a streak-free finish. How do I use Prestone Screen Wash?

Whatever the road throws your way, you can rely on Prestone Screen Wash to keep things clear. Our screen wash melts ice down to -18°C and is powerful enough to remove even the most stubborn deposits – including bird droppings and dead insects – for complete confidence in all conditions. How do I replace Prestone Screen Wash? Not only is Eco Refill screen wash much better for the environment, but you still get the same level of high-performance cleaning as from our ready-to-use screen wash. And in winter, that’s important, with our powerful cleaner cutting through the worst dirt, salt, and road dirt that you have to deal with out on the road. We tried seven different types, testing them for freeze resistance in winter conditions and cleaning ability at weaker summer concentrations. 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 Choose concentrated or ready to use screen wash– Our ready to use screen wash is convenient, while our concentrated version lets you adjust the ratio of water depending on the conditions. They both have the same properties, so choose the one that’s best for you.

That means total clarity and 100% visibility, as well as zero chance for dangerous sun dazzle to interfere with your view of the road. It’s the best way to remove streaks, bugs and dirt from the windscreen– car windscreens are exposed to all sorts out on the road, and water alone just isn’t able to cut through that dirt. Thanks to powerful cleaning agents, screen wash makes light work of most marks, streaks and stains, so you’re guaranteed excellent visibility. The results make it difficult to believe these tablets are much more than just dye, and to compound our frustration the liquid also seemed to stain our containers and give our hands a blue tinge. Verdict

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.As you might expect from the well-known and respected brand like Autoglym, the screenwash did well in the cleaning tests – but it’s expensive to use at winter temperatures. Plus, summer means the arrival of a sneaky danger — sun dazzle. Dazzle occurs when the sun’s rays shine on dirt and grime on a car’s windscreen, limiting visibility for the driver. If you keep your windscreen free of dirt and smears, then you’ll get better visibility and won’t have any nasty sun related surprises. Myth 2: Don’t use screen wash –water does the same thing First we calculated the costs of each in their winter and summer mixes. For the former we chose coverage down to about -10C, where there was a choice of mixes.
