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.

Screen wash is the fluid that drivers are most familiar with and confident in topping up. It’s quick and easy to replace, and you’ll typically need to fill it up at least once a month – or more frequently – depending on mileage, driving conditions and time of year.

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.
