Prestone PSCW0021A Summer Screenwash 5L

Product Information

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

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. 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.

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! 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 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. At a summer mix rate of 4:1 the Halfords wash cleared both the glue and the oil after a few wipes, giving the best cleaning performance in the test. Autoglym Ultimate Screenwash 500ml At the summer mix ratio the cleaning performance was adequate, clearing the oil and leaving a small residue of glue, but no smearing.

If that wasn’t enough, we’ve solved the problem of accidental spills by redesigning our screen wash bottles. No more sloshing screen wash all over the engine bay or having to use a funnel; simply pour and go for unrivalled visibility and cleaning power out on the road. How it Works It will help keep your car in good condition – screen wash is specially developed for cars, so you know that it’s safe to use. If you use water or household cleaners, there’s a risk of damaging the paintwork over time, so we’d always recommend high-quality screen wash. 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 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.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.

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. In summer driving conditions, your visibility can be affected by tree sap, dead insects, and dangerous dazzle from the sun. 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. ConclusionAs well as removing deposits and dirt fast, Prestone Extreme Performance Screen Wash also dries clear thanks to our new and improved streak-free formula.
