Many motorists would agree that all screenwashes are not the same after experiencing a badly smeared windscreen caused by road grime or insects which refuse to budge however much you try to wash them away. Yet some screenwashes are little more than coloured water and make exaggerated claims that cannot be substantiated.
Autoglym believes that a reliable, effective screenwash is essential to vehicle safety and Autoglym “All Season” Quick Clear Screenwash provides a number of significant performance advantages. It inhibits smearing of insect remains and clears contaminants rapidly, plus a high dilution rate increases economy. Use throughout the year at recommended dilution rates for safe, smear-free driving. and claims to be safe on paint and trim
