Our screen wash melts ice down to -18°C and is powerful enough to remove even the most stubborn deposits – including bird droppings and dead insects – for complete confidence in all conditions. How do I replace Prestone Screen Wash? 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 In summer this makes it seem good value compared to some ready-mix rivals, but the advantage disappears in winter.

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. ConclusionWe tried seven different types, testing them for freeze resistance in winter conditions and cleaning ability at weaker summer concentrations.
