Your window wiper fluid is ineffective, thick, and seemingly doing more harm than good. As temperatures drop, the viscosity of wiper fluid changes and because less effective the colder it gets. To avoid this, make sure you have the right washer fluid for the season. We suggest using a de-icing washer fluid for snow conditions; it’s formulated with chemicals that reduce the adherence of ice and snow on your windshield, and also contains a small amount of anti-freeze to melt snow and ice.
In addition to wiper cleaner, engine oil, antifreeze, power steering, and transmission fluids can become viscous, changing the quality and effectiveness of each.
