Car Wiper Blades Noise And How To Overcome It
There’s nothing more annoying than noisy Car Wiper Blades. How many times have you found yourself just hitting the 1 wipe button, and that only when your visibility gets really bad? That’s very annoying and potentially risky, but thankfully, you can take some simple actions to beat the problem.
First of all, keep your whole windscreen clean. When you wash your car; don’t forget to lift the wiperblades off the windscreen and wash and rinse the area below them, even though this isn’t the bit you look through.
It’s important to keep the whole screen clean, because, when the windscreen is wet, the dirt particles become extremely mobile, and can get beneath the edge of the blade. This has several effects:-
Firstly, the particles between the screen and the blade cause uneven contact|friction between screen and blade. This causes the blade to vibrate, generating noise. This problem is made worse if you have rubber Windscreen Wiper Blades, because they loose their flexibility with age and exposure to Ultra Violet Light, Ozone, many Screen Wash ingredients, and pollution. As the blade becomes stiffer it’s far more likely to jump and judder as it moves from clean to dirty glass.
Secondly, the dirt & grit particles abrade and cut the surface of the wiper blade right at the critical working edge. On rubber Car Wiper Blades this also increases the area for UV, Pollution, Ozone and solvents to attack the rubber, so speeding up the stiffening process, which in turn makes the noise worse.
Thirdly, the dirt and grit particles settle on the non-working surfaces of the wiper blade. These particles harbour road grease & pollutants, which attack the rubber from the sides, causing more hardening and therefore more susceptibility to juddering and noise.
When the blade looses its flexibility and then is subjected to juddering, it tears at the mounting. As a result the rubber wears or tears at the critical mounting points, and the mounting points themselves become deformed and loose. This in turn leads to more judder, and so the cycle speeds accelerates.
Flat Wiper Blades are much more resistant to this last problem, because they have a much broader anchor point between the blade and the Parts which hold it in place.
As usual, prevention is much better, easier and cheaper than a cure. A stitch in time really can save 9.
Careful cleaning of your Car Wiper Blades will markedly reduce the tendency to judder and make noise, and if you’re not lucky enough to have Silicone Windscreen Wiper Blades, it will also markedly slow down the predictable aging process of the rubber.
So, to sum up
To lessen and avoid the problem on existing Car Wiper Blades, keep them clean, and be prepared to replace them as soon as the rubber shows signs of stiffening, porosity, cracking or tearing.
When you replace your Car Wiper Blades consider using Retrofit Flat Wiper Blades, because they hold the blade much more securely, so reducing the opportunity for vibration in the first place, and tearing in the second.
Better still, get Silicone Windscreen Wiper Blades. The silicone resin stays completely flexible throughout life, and ensures smooth quiet operation for at least 3 times the life of even the best rubber Car Wiper Blades.
Best of all get Silicone Flat Wiper Blades. They combine all the advantages of Silicone Windscreen Wiper Blades with the looks & performance of Flatblade Wiper Blades.
