How important are those little Windshield Wipers

Windshield Wipers, though form a very small part of your car's ecosystem, it is unimaginable to drive without them during this treacherous monsoon season.

I dread thinking about those times, when these were not invented and may be drivers had to poke their head out of the windows while driving. The first set of wipers put to use in a car's ecosystem were designed and patented by Mary Anderson in 1903.

By Mary Anderson(Life time: 1866-1953) - Original publication: US Patents Office. web, Public Domain,

The Intermittent Wipers that we use for the windshield of our cars today, were inspired by the blinking of the human eyes. This wiper technology was suggested in 1962, by Robert Kearns, an engineering professor. Unlike the earlier versions of wipers that used to wipe continuously, these were the first set that would pause for a while before wiping the windshield again. Thereby, aiding the driver with several speed options in accordance with the severity of the weather.

Since then we have come a long way, in terms of engineering related to these wipers. Despite of it all, we have not learned how to care for them properly. Most of us don't change the wiper blades even once during the lifetime of our vehicle. Wiper blades are a combination of Rubber and Metal, both of them being reactive to the damages caused by natural agents.

How often should you change the wiper blade ?

Atleast once or twice in an year.

Reasons to change the Wiper Blades Frequently:

  • The rubber of the wiper blade can suffer damages due to harsh sun, causing it to crack and breakdown and separate from the frame, thereby exposing the windshield to the metal frame, which may cause scratches and grooves on the windshield.

  • The metal frames of the blade may deform or bend due to excess heat, thereby causing inconsistent contact with the windshield and cause skipping of the blade while wiping. lack of use for a very long time may also result in bending of the frame.

  • The rubber of the wiper blades can dry up, harden and crack, thereby causing streaking on the windshield while wiping. streaking can also happen because of accumulation of airborne debris on the surface of the wiper blades, like sand, mud, dust, etc. Streaking may result in formation of scratches on the windshield.

  • The rubber blades can also see damage because of the salt water in the air both near the shores or inland. Acid rains also cause severe damage to the wiper blades.

  • Extensive use of wiper blades, may cause the squared rubber edges to round up, thereby resulting in wearing down of the wiper blade and inefficent wiping.

  • Be extremely cautious and dont use the wiper blades on dry windshield. wiper blades on dry windshield act like sand paper.

Efficient wiper blades are extremely important for unobstructed driving. It is advisable to check on them frequently.

Drive Safe! Stay Safe!
