The car duster is a dry cleaning tool designed to lift light dust from a vehicle’s surface without using water. It typically features a long handle and thick cotton or microfiber strands treated with baked-on paraffin wax. This wax treatment creates a static charge that lifts dust like a magnet rather than dragging it across the paint. It is perfect for maintaining a car between washes. However, it should only be used on dry, lightly dusty cars; using it on wet mud will scratch the paint.
