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. 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?

Winter might mean more rain, slush and road dirt on your windscreen, but summer offers up its own set of visibility problems. From dust to dead insects, your windscreen goes through a lot, whatever the season — so you should always make sure your car is filled with premium screen wash. After all, it’s the law.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. 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. 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. Prestone Maximum Visibility Summer Screen Wash is a high-performance screen wash that helps you to achieve perfect visibility in all driving conditions. There is little aroma, no foaming and the fluid turned to ice as soon as the temperature dipped below zero. In the cleaning test it left smears from the oil and had no more effect on the glue than plain water.

The company has opted to make the products look different by colour (and smell) coding them according to the temperature protection level. The -20C liquid we selected is green and ‘Citrus’ flavour.

Used throughout the spring and summer months, Prestone Summer Screen Wash provides a reliable solution to keeping your windscreen clean and clear. Try it out and we promise you’ll see the difference.

Once applied, the product gets to work instantly, melting through dried-on dirt and deposits to lift stains, reduce smearing, and leaving your windscreen clean, clear, and ready for whatever the road sends your way. 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. 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. Unless your classic is very old, you’ll need to make sure there is some fluid available when you press the button to wash the windscreen. In winter it will help get rid of road grime and salt, in summer it helps clear fly splats, dust and diesel film.
