In the know: Do you really need to raise your windshield wipers when parked?

You might have seen windshield wipers propped up  when automobiles are parked. But is it just a force of habit, or does it have some science in it?

Today, we’re going to find out why you need to raise your windshield wipers when parked.

Windshield marks

Leaving the windshield wipers on the actual windshield might cause particular marks to appear on the glass, especially when your car is parked outside on a hot day.

The heat from the windshield might speed up the degradation process of the rubber material on the wiper causing it to melt and leave marks on the glass.

It can damage the rubber

As we have briefly covered above, leaving the windshield wipers in close contact with the glass might speed up the deterioration process of the elastic material on the wiper.

On that note, propping the windshield wipers up could somehow combat the likelihood of you having to buy new wiper blades more frequently.

They can catch dirt

Keeping the windshield wipers on could cause dust and dirt to accumulate on the edges of the rubber material on the wiper. These particles might stick to the elastic material and scratch the windshield when the wipers are activated.

Bottom line

Like most of the lessons your fathers and your uncles taught you, there are sensible reasons why you should raise your windshield wipers. While it will not have any substantial upsides, doing so could help you reap the so-called benefits of following this practice.
