Prestone Extreme Performance Screenwash

SCREENWASH

EVEN with the best wipers, you’ll need the top screenwash to help shift bird lime, traffic film and general grime. Prestone’s formula won our 2017 test, as it’s a good all-rounder (for summer and winter use), topped all our assessments and lasted a full 150 minutes in the deep freeze. Just remember to use the right concentration for winter, as this will help prevent the reservoir and pipes freezing overnight or even on the move if wind chill is strong.
