The great thing about Prestone Screen Wash is that it’s safe to mix with other products. That means you can add screen wash anytime without worrying about contamination and a drop in cleaning performance. How does Prestone Screen Wash work?

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? 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: 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 WashIt will prevent freezing – make sure you use a high-quality screen wash with a low freeze rating. That way, on cold nights, the water in the reservoir won’t freeze solid and cause damage. 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 dramatically reduce sun dazzle – sun dazzle is dangerous and can easily cause accidents any time of the year. Making sure the washer reservoir is kept topped up will ensure you can keep the windscreen free from smears and streaks which cause dazzle. 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. 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.

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. We 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.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. 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 In summer this makes it seem good value compared to some ready-mix rivals, but the advantage disappears in winter.

Top up the screen wash – Pour screen wash directly into the reservoir without removing the filter that sits inside the filler tube. You can use a funnel if needed to avoid spillages. Continue pouring until you start to see fluid coming up the transparent tube; fill to the ‘max’ line and replace the cap. With the needle inserted, carefully adjust the nozzle so that the opening is directed at the windscreen. Then, remove the needle and test the spray. If it’s still not properly aligned, you may need to repeat the process.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.
