SCREENWASH
Count on these to shift bugs and road grime from glass all year round
EVEN drivers who would never dream of cleaning their car, let alone waxing or claying it, buy screenwash. It is an under-bonnet essential all year round, shifting filthy road grime from the windscreen in winter and dead bugs in summer.
And that’s the problem when buying screenwash – different dilutions are often required for different seasons, which makes picking the best product confusing. A screenwash that is cheap in summer can work out very expensive in winter. And one that shifts bugs easily may ice over at the slightest sign of a cold snap.
Our test hunts for the best year-round solution. We rated cleaning ability, then put the products in a deep freeze to see how they’d fare in winter. We also calculated seasonal costs.
“We often find that the winner in our tests is the product that performs well across a range of criteria, and Prestone’s does just that”
