1. CLEAN THE WINDSHIELD WIPERS

This is the first and easiest solution to apply. Over time, a thin film of dirt, grease, and other filth builds up on the wiper blades.

This causes the wipers to smear but also to start chattering. The solution, of course, is to clean them.

There are numerous ways to do this. The usual way is with a window cleaner and paper towels or with a chamois cloth.

You can also use wet wipes as they have a certain percentage of rubbing alcohol in them which can clean the wiper blades real good.

Besides this there is a WD 40 hack, we’ve made a separate article and video on this topic about how to revive and clean old wiper blades. Click here if you want to see it.

While you’re at it, it would be good to clean the windshield also. Over time a thin film of filth forms on the windshield that the wipers and washers can’t take off. It can also contribute to chattering wipers.

2. CHECK THE WIPER BLADE CONDITION

While you’re cleaning the wiper blades, check their condition. Chattering is often caused by worn-out blades. Check if they’re brittle or torn.

If they are, replace them otherwise all of these tips are pretty much useless.

3. ADJUST THE WIPER ARMS-LESS KNOWN REASON FOR CHATTERING WIPER BLADES

If everything is clean and the wiper blades are in good condition, then check the wiper arms.

Over time, for various reasons, they may get twisted to some extent. This leads to the wiper blades unevenly falling onto the windshield.

When everything is OK, then the wiper blade rubbers fall onto the windshield at a 90-degree angle.

If you see the blade laying onto the windshield instead of standing, then this is a sure sign you should do this.

There are two ways of doing this, you can take off the whole wiper arm, put it in a vice for instance and straighten it there.

But to avoid the extra work you can do it on the car, just be careful you don’t accidentally hit the windshield with the wiper arm.

All you’ll need are two pliers and some insulation tape. So, raise the wiper arm and put some insulation tape in two places where you have enough leverage to twist it.

The tape prevents scratches and future rust on the wiper arm.

Instead of tape, you can use a piece of cloth, for instance, the point is to protect it.

Take the pliers and twist the wiper arm until it’s straight again. Don’t be surprised if you need some more strength as some wiper arms are thicker and more resilient.

If needed use something with more leverage like a vice grip, french key, maybe a pipe wrench.

After that return, the wiper blades back into place and if everything is OK, they will fall on the windshield at a proper angle.

CONCLUSION

So, solving the problem of chattering wiper blades is pretty simple.

First, clean the wiper blades and windshield. If the blades are worn out, replace them. If they’re OK, then check the wiper arms and straighten them if needed.

All of this, in real life, takes up about half an hour of your time at most, if everything goes as usual.

A small amount of time for the benefit of getting rid of the wretched screeching and chattering every time you turn on the wipers.
