There’s nothing more annoying than noisy Windscreen Wipers. How many times have you found yourself just hitting the one wipe button, and that only when your vision gets really bad? That’s very stressful and potentially risky, but thankfully, you can take some simple measures to avoid 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 underneath them, even though that isn’t the bit you look through.
It’s important to keep the whole windscreen clean, because, when the windscreen is wet, the dirt particles become extremely mobile, and can get under 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, creating noise. This problem is made worse if you have rubber Windscreen Wipers, 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 Windscreen Wipers this also increases the area for UV, Pollution, Ozone and solvents to attack the rubber, so accelerating the hardening 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 faster 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 Blade 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 always, prevention is much better, easier and cheaper than a cure. A stitch in time really can save 9.

Careful cleaning of your Windscreen Wipers will markedly reduce the tendency to judder and make noise, and if you’re not lucky enough to have Silicone Windscreen Wipers, it will also markedly slow down the predictable aging process of the rubber.

So, to recapitulate
To lessen and avoid the problem on existing Windscreen Wipers, keep them clean, and be prepared to replace them as soon as the rubber shows signs of hardening, porosity, cracking or ripping.

When you replace your Windscreen Wipers consider using Retrofit Flat Blade Wiper Blades, because they hold the blade much more securely, so reducing the opportunity for vibration in the first place, and ripping in the second.

Better still, buy Silicone Windscreen Wiper Blades. The silicone resin stays constantly flexible throughout life, and gives smooth quiet operation for at least 3 times the life of even the best rubber Windscreen Wipers.

Best of all buy Silicone Flat Blade Wiper Blades. They combine all the advantages of Silicone Windscreen Wipers with the looks & performance of Flat Blade Wipers.
