Accumulation of dirt and other contaminants

As you drive on the road, the wind lifts dirt, dust, sand, and other contaminants across your way. The windshield’s responsibility is to trap those dirt, dust, sand, or contaminants and wipe them off with the wipers.

However, some of the dirt or contaminants stick to the wipers, resulting in a squeaking noise over time. The solution to this challenge is to thoroughly clean your car’s windshield wipers with warm, soapy water. Then wipe the windshield wipers’ blades with rubbing alcohol. 

Defective installation of windshield wipers

If the installation of your car’s windshield wipers is defective, you will necessarily experience a squeaky sound.

A common example of defective installation is when the wiper assembly is wrongly positioned in such a way that allows airflow between the car’s windshield and its wiper blades. In this, you need to uninstall and reinstall the windshield wiper assembly.

Over usage of windshield wipers

Windshield wipers become brittle over time due to over-usage. When this happens, you will constantly hear a squeaky sound each time you engage the wipers to clear off the water, dust, etc.

If you discover that your vehicle’s windshield wipers are old, kindly replace them as soon as possible. This will automatically stop the squeaky noise immediately.

Factory defects

This is a rare issue. However, manufacturers may produce windshield wipers with some defects due to mass production errors. So, if you are wondering, “Why do my brand new wiper blades squeak?” This is the issue.

When mass production defects occur, users may end up buying defective windshield wipers and start to experience a squeaky sound from day one or after some time.

If you find out that the problem is due to the manufacturer’s defects, kindly return the wipers (especially if they have a warranty). Otherwise, you may need to get a new set of wipers.
