Windscreen wipers can be very annoying at times when they begin to squeak or shudder. This can be quite annoying to the ears and can also distract the driver when on the road. But what makes windscreen wipers shudder in the first place?
This problem on the windscreen may arise due to faults or damage to the wipers. There are however small procedures that can help reduce or end this annoying shudder sound.
Solution #1 – Ensure Proper Movement
First make sure the rubber of the wipers is flexible and can flop over in both directions. The blade should be able to move across the windshield easily and freely. A normal windshield wiper should be flexible enough to always sweep water off the windshield and if this isn’t the case, you should check to see what is preventing it from doing so.
If the wipers are dirty or overly stiff you can try try rubbing alcohol on the blades to clean off dirt and oil and also soften them up a bit.
Solution #2 – Ensure a Clean Windscreen
Another remedy to squeaking or shuddering wipers is cleaning the windscreen thoroughly. Make sure you wash the outside of the windscreen as part of your regular car washing process to remove any debris or dirt.
The windscreen should be free from waxes and oils as this can make the glass very slippery thus causing problems. After washing the whole car use a glass cleaner and cloth to finish off the glass leaving it crystal clear.
Also don’t forget to top up your windscreen washer reservoir under the bonnet with fresh water, for clearing your windscreen while driving.
Solution #3 – Regularly Replace Wiper Blades
It is advisable to replace wiper blades every 6 to 12 months due to wear and tear. Depending on the brand of wipers and your vehicle usage you may find that you get more or less use than this. The last thing you want to do is wait for your wipers to deteriorate from the weather and have the metal of the wipers scratch your windscreen. This may require a windscreen replacement.
When installing the wiper blades, check the tightness level. Too little or too much tension between the glass and wiper can cause the shuddering or squeaking.
Helpful Bonus Tips
Some websites recommend wiping your wiper blade edges with alcohol at least once every month. This can not only reduce shuddering but also gets rid of debris, grease or loose bits of rubber from the blade. Doing this procedure is said to increases their lifespan.
However some rubber blades are filled with graphite powder for reduced noise. This is noticeable as they have a graphite shine. If this is the case you should avoid wiping them with alcohol as doing so could strip the graphite coating.
There are also a few things you should avoid doing so as to avoid damage on your wipers. These include:
- Avoid waxing your windscreen as this would lead to slippery blades that are not efficient.
- Do not use the windscreen wipers when the glass is frosty as this can cause the wipers to tear.
- Do not ever add dishwashing detergent into your washer fluid as this would leave the glass on your vehicle “squeaky” clean as it normally does to the dishes.
