Want to know how to keep wiper blades from icing up? If you cover them, they can’t get ice on them. Wiper covers are readily available, or in a pinch, you can cover the blades in plastic bags. Deicing washer fluid helps keep the wipers free during use. Running the defroster warms up the windshield, which keeps the wiper blades from freezing to the glass. You should also consider switching to winter wipers. These have plastic covers that keep water from freezing on the wiper frame.
