What Effect Does Replacing Your Porsche Wiper Blades Have On The Windshield?

Many car owners are not as conscientious about their windshields as they are about their car engines. This is strange because windshields complement safety. Think about it for a second. Worn wiper blades are safety hazards. That’s because as much as 90% of your driving choices and decisions are based on clear and unobstructed view of the road. Your car’s wipers should therefore provide you a windshield that is as clean as possible. You have no choice but to replace your wiper blades often.

As you do this, keep in mind that airborne contaminants, ozone, oil, sunlight, dirt and dust all reduce and even weaken your wiper blades ability to provide you with an unobstructed view.  Remember too that exposure to ozone and sunlight cause wiper blades to age even if they have not been used for a long time. Replacing them will therefore go an extra mile to enhance safety. You have to consider the following factors though.


Weather conditions play a vital role in your windshield wiper deterioration. Freezing and near freezing temperatures make the wiper blades rubber brittle and hard. This makes it easy for them to tear and break. Hot weather on the other hand warps the rubber thus preventing the blade from seamlessly wiping the windshield. That is why inspecting your windshield and wiper blades should be a routine habit for you. Only then will you be able to spot anomalies that should be fixed on time.

Blades Performance

Replacing your Porsche wiper blades at least once a year will without a doubt have a positive impact for your as a driver as far as safety is concerned. Remember though, that the blades’ ability to effectively clean the glass depends on factors such as the slope and the area of your car’s windshield. Windshields in today’s Porsche models are more sloped than they were before for improved aerodynamics. However, a luxurious ‘cab-forward’ windshield with a wide glass surface area re-directs more wind with ease against the wipers. This can force the wiper blades away from the windshield if you are moving at a high speed. You do not have to worry about this as most modern Porsche models feature wiper systems that are designed to resist lift.

Spring Tension

This is also very important. The amount of spring tension on your car’s wiper arm keeps the wiper refill in tight and strong contact with the windshield. This provides an excellent squeegee effect. Your choice of wiper blades should incorporate a beam-balance design complete with multipoint suspension systems. Such a design eliminates smearing. It also prevents streaking in both directions.

The Right Blade 

 Shopping for the right blade should not be a problem if you have a car manual that specifies what you should buy. In the absence of a manual or any resource to guide you, always go for wiper blades that are designed to guarantee great aerodynamics, have heavy gauge steel frames and have lower profile super structures.  Then by all means, replace your wiper blades after every 6 months even if you live in dry places.
