Abstract: A device for preventing the accumulation of frozen precipitation on and around an automobile's windshield wipers. The device is defined by an elongated, substantially conical sleeve that is formed of polyester laminate industrial fabric. The sleeve is slid onto the windshield wiper of an automobile in advance of oncoming frozen precipitation. After frozen precipitation has accumulated on the automobile, the precipitation can be cleared from atop the protective sleeve and the sleeve can be removed to expose a clean, precipitation-free windshield wiper. Then windshield wiper can then be employed immediately in a conventional manner for cleaning the windshield of the automobile without being impeded by residual frozen precipitation that could otherwise accumulate on the wiper.
