Streaks and smears
You may start to see streaking and smearing across the screen during their operation. Sometimes this can be caused by debris that can be cleaned easily, but take a closer look at the rubber to see if there are any signs of it being worn out.
Windscreen wipers are generally silent. You may sometimes hear a squeak or screech which could mean it’s improperly fitted or in some cases is an indication of worn-out blades.
This usually happens when the wipers are unused for a prolonged period of time which can cause improper contact of the rubber with the windscreen.
In this case, you may notice that the leading edge of the blade has started to come adrift from the main body of the blade.
The lifespan of wiper blades depends on the quality, weather and extent of usage but can get worn out in 6-12 months. Make sure you keep an eye on any signs of replacement mentioned above to avoid causing damage to the windscreen. These are a few tips and tricks on how to take care of your wipers.
