A wiper blade is the blade of a windshield wiper. Temperature extremes on the windshield have a damaging effect on wiper blade performance. Install new wiper blades at least once a year to ensure good vision. We have two different wiper blades i.e., Steel and plastic.

A windscreen wiper, windshield wiper, wiper blade (American English), or simply wiper, is a device used to remove rain, snow, ice, washer fluid, water, or debris from a vehicle’s front window. Almost all motor vehicles, including cars, trucks, buses, train locomotives, and watercraft with a cabin—and some aircraft—are equipped with one or more such wipers, which are usually a legal requirement.
A wiper generally consists of a metal arm; one end pivots, and the other end has a long rubber blade attached to it. The arm is powered by a motor, often an electric motor, although pneumatic power is also used for some vehicles.

The blade is swung back and forth over the glass, pushing water, other precipitation, or any other impediments to visibility from its surface.
