Like other car accessories, the windshield wiper needs regular maintenance and washing. Even the sturdiest material needs to be cleaned regularly. Though the winter wipers do not need high maintenance, give them a wash once a week to remove the accumulated debris and snow. You could use a damp cloth to wipe the windshield wipers blade. Never turn the wipers on until you have removed the accumulated snow. You could also pull the wiper away during winter to keep them from ice.
