Prestone PSCW0029A Winter Screenwash, 5 Litre

Product Information

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. 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. To help, we’ve put together a list of frequently asked questions that should fill you in on all things screen wash. Take a look below. What is Screen Wash? 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.

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

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.

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. 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. At the summer mix ratio the cleaning performance was adequate, clearing the oil and leaving a small residue of glue, but no smearing.

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 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 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 Prestone Screen Wash comes in both a concentrate and ready to use formats. When using concentrated screen wash, always follow the instructions on the bottle to get the right ratio of screen wash to water – this can change depending on the season.

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! 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) 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. 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. 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.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. Prestone has developed products to keep you driving all year round.

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!

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. That means total clarity and 100% visibility, as well as zero chance for dangerous sun dazzle to interfere with your view of the road. 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. Lift the bonnet and locate the screen wash reservoir cap; it’s typically blue with a windscreen icon on the top. Flip open the cap, hold the lid out of the way, and begin pouring.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. 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. 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.
