Maintenance of the wiper blades after the summer

The heat and the summer sun are putting a strain on the wipers of your car. The rubber dries out, deforms and loses its effectiveness. Proper cleaning and maintenance after the summer season will extend their lifespan and ensure optimal visibility for your safety. Discover our tips for wiper blade maintenance.

What is the average lifespan of brooms ?

The standard lifespan of a pair of wiper blades is around 500,000 scanning cycles, representing approximately 12 months of normal use. This duration varies considerably depending on your geographical area.

In Mediterranean regions where the weather remains mild, wipers can last up to 18 months. Conversely, in Brittany or in mountainous areas, their replacement is necessary every 6 months due to frequent rainfall.

Wear factors include UV exposure, temperature changes, de-icing salt and air pollution. A motorist driving daily in the city uses his wiper blades more than a casual driver in a rural area.

The signs that indicate that they need to be cleaned

Irregular marks on your windscreen after brushing are the first warning signal. A cleaning is required when you notice poorly wiped areas or persistent streaks, even in dry weather.

Jerky movements or an unusual rubbing sound during sweeping often reveal a build-up of residue on the rubber blades. Some wiper models are equipped with a black tab that turns yellow when maintenance becomes necessary.

Another telltale sign : the formation of a greasy film on the windshield despite the use of windscreen washing. In this case, a thorough cleaning with hot water and white vinegar will restore good visibility, which is particularly crucial in bad weather.

How to effectively clean your wipers ?

For optimal cleaning, start by lifting the wiper blades and place a soft cloth under each arm to protect your windshield. Prepare a solution mixing windscreen washer fluid with warm water in a clean container.

Gently pass a soft sponge soaked with this solution over the entire length of the rubber blades. A loosener on the axes of the wipers will facilitate their rotation and prevent jerky movements.

To finalize, apply a silicone-based product on the rubber parts. This step allows to soften the material and guarantees a smooth sweeping. Let dry for a few minutes before repositioning your brushes on the windshield.

How to soften the wiper rubber ?

Isopropyl alcohol represents an effective solution to restore flexibility to rubber blades. Apply it with a clean cloth along the entire length of the wiper blades, making regular movements.

White vinegar is a natural and economical alternative. Mix it in equal parts with warm water, then gently rub the wipers with this preparation. The properties of vinegar not only soften the rubber but also eliminate stubborn residues.

A very fine sandpaper (grit 600) can also revive the surface of the rubber. Exert a minimum pressure when sanding to avoid damaging the blade. Pure petroleum jelly also offers excellent results : a thin layer is enough to restore the material’s elasticity.

The right daily maintenance gestures

Prevention remains the best strategy to keep your wipers in good condition. Before each journey, quickly check their cleanliness and remove the leaves or debris stuck under the wipers .

In freezing weather, avoid operating your brushes without first defrosting your windshield. A simple trick is to place a small plastic shim under each wipers to raise them during the night parking.

During hot weather, protect your wiper blades from direct sunlight by raising them or covering your windshield with a sunshade. A monthly cleaning with a product adapted to the season guarantees optimal performance. In winter, opt for an antifreeze screen wash that will preserve the rubber of your wiper blades.

When should one change its wipers ?

A wear indicator on some models changes from black to yellow to signal the appropriate time for replacement. The average duration between two changes varies depending on your geographical area and your driving habits.

Signs that do not deceive : persistent streaks despite a thorough cleaning, a squealing noise on contact with the windshield or a wipe that lacks uniformity. In these situations, replacement becomes essential to avoid any visibility problems and ensure your safety.

Drivers living in coastal areas or in very sunny regions will have to renew their wipers more frequently because of sea salt and UV. To ensure optimal visibility, prefer models adapted to your climate : flat blade for rainy regions, reinforced version for mountainous areas.

What size of wipers for your vehicle ?

The length of the front wipers varies considerably from one vehicle to another. The wipers on the driver’s side is usually between 45 and 75 cm, while that of the passenger is shorter by a few centimeters for optimal coverage of the windshield.

To identify the exact dimensions suitable for your car, consult the user manual or measure your current wipers. Another practical solution is to check the reference written on the back of the box of your old brooms.

The rear wipers require special attention with dimensions between 25 and 40 cm depending on the configuration of your rear window. A wiper that is too long or too short would compromise your visibility and risk damaging the mechanism.

The best products for maintenance

The brands Valeo and Bosch dominate the market with their professional ranges of cleaning products. Their special rubber cleaning solutions ensure optimal durability of the wipers.

The Champion cleaning kit, including a degreasing spray and a microfibre cloth, is an excellent choice for complete cleaning. The brand also offers a hydrophobic treatment that allows water to drain on the windshield.

For a controlled budget, natural solutions like the hot water-white vinegar mixture remain effective. A silicone-based cleaner applied monthly will extend the life of your wipers, while a graphite grease on the shafts will optimize their movement.

Tips for a perfect installation

How to choose your wiper blades ?

The selection of wiper blades is based on several essential criteria. The type of driving plays a determining role : frequent use on motorways requires aerodynamic models, while urban use will prioritize robustness.

The climate of your region also guides your choice. Mountainous areas require reinforced wipers that are resistant to cold and frost, while coastal regions require increased protection against corrosion.

Remember to check the compatibility with your fastening system. A simple glance under the old wipers reveals the type of attachment to look for. For hassle-free installation, some models offer universal adapters that make mounting easy.

How to protect your wipers in summer ?

The summer period particularly puts your wiper blades to the test. To maximize their lifespan during hot weather, adopt a few simple actions. Park your vehicle in the shade or use a special protective cover for the windshield.

Consider raising your wipers during extended parking to prevent rubber from sticking to the burning windshield. A little-known trick is to apply a hydrophobic product on the rubber blades to create a protective barrier against UV.

Regularly clean your wipers with a damp cloth to remove residues that accumulate more quickly in the summer. This preventive action will avoid the appearance of micro-scratches on your windshield.

How to change the blades of your wipers ?

Replacing the wipers starts with an essential step : protect your windshield by sliding a thick cloth under the raised metal arm. Then gently lift the arm vertically.

Locate the attachment system under the old wiper- usually a hook or push button. Actuate the unlocking mechanism and remove the old wiper by sliding it.

Take the new wiper and precisely align it on the arm. A sound “click” confirms the correct installation. Check the strength of the assembly by pulling slightly on the wiper before resting it on the windshield.

Repeat the operation for the second wiper while respecting the same precautions.
