Not using winter wipers
Regular windshield wipers have four little fingers that hold the blade in place. Winter wiper blades are one piece, or that part is covered up.
“It keeps the ice and snow from building up in the blade so it stays in control when you’re driving down the street,” Paul said. “Otherwise, you’ll have to stop and smack it off.”
Paul has seen people reach out their windows and try to knock snow or ice off the blade while driving. This dangerous move is not recommended.
