Prestone PSCW0029A Winter Screenwash, 5 Litre

Product Information

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 That means total clarity and 100% visibility, as well as zero chance for dangerous sun dazzle to interfere with your view of the road. 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) 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.

The instructions recommend it is used at the ‘optimum clean’ dilution ratio of 1:9, which stops freezing down to a claimed -3 oC. We understand that a lot of drivers like to save on the cost of motoring, and one such cost-cutting measure is to ditch screen wash in favour of plain old water. Sadly, water doesn’t deliver anywhere near the performance of high-quality screen wash, for two simple reasons. Screen wash reservoir caps are almost always blue, which should make it easy to find under the bonnet. Depending on the size of the bottle, we’d recommend using a funnel to add the screen wash. If you don’t have one to hand, turning larger bottles on their side can help with pouring. Prestone has developed products to keep you driving all year round. This unique Screen Wash works to achieve max visibility to ensure safer driving throughout Autumn and Winter. 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.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.

The second reason is that water simply won’t remove tough dirt, stains and marks caused by dead insects and tree sap. Over time, this can lead to reduced visibility, and prolonged abrasion could even damage the windscreen. Myth 3: You can use washing up liquid or other household cleaners Prestone Screen Wash contains powerful cleaning agents that remove tough deposits and ensure a streak-free finish. Combined with the optimum quantity of antifreeze, our windscreen washer fluid guarantees maximum protection and visibility in all driving conditions. By simply adding water to the super-concentrated formula, 500ml of Eco Refill makes 5 litres of winter screen wash. Use Eco Refill in an empty 5-litre screen wash bottle and save over 75% plastic each time!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 This depends on your average mileage, driving conditions and the time of year. You may need to replace screen wash every week if you cover a lot of miles, particularly in the winter. In summer, you’ll generally use less screen wash, though it will be needed to remove streaks and dust from the windscreen to prevent dangerous sun dazzle.

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. 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. Cars rely on two different antifreeze products — antifreeze in screen wash and coolant/antifreeze. Both serve different purposes, but some people get the two muddled up, or think they’re the same thing. The screenwash is new and improved, using a streak free formula to keep your windscreen clean and clear. Decades of car maintenance know-how have gone into Prestone Extreme Performance Screen Wash, so you can be assured of outstanding performance with every spray. And with year-round cleaning guaranteed, you can use the same screen wash through all four seasons – for maximum cleaning performance and convenience.However, there was some good news. As we didn’t need the full -20C protection we economised and tried a few different concentrations to see how they fared in the freezer. A mix of 50/50 with water was still squirting after 12 hours at -18C, so it would seem Halfords is understating its performance. 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.
