Using Winter screen wash in summer
« on: »
Hi folks
Is prestone screenwash (winter formula) safe to use in summer. Only apprehension is that it will have de-icer which might strike more streaks on windshield in summer. Otherwise what stop it from cleaning the windshield in summer too. Screenwash name is Prestone Max visibility screenwash (winter formula).
