Regularly cleaned car windows not only ensure a better view, but also a much safer drive.

How do you effectively clean the windshield from the outside?

Correct cleaning and degreasing

We recommend cleaning the car window with a gentle cleaning agent such as our Biosativa® cleaner to remove the coarse dirt. The windshield should then be degreased with a cleaning agent such as our isopropanol 99.9% cleaner. The high-purity isopropanol cleaner is characterized by rapid evaporation so that no streaks remain. Ideal for glass cleaning!

Note: When using the isopropanol cleaning agent, protective equipment should be worn and good ventilation ensured.

Tips for removing stubborn dirt such as tree resin and bird droppings

Stubborn dirt on the windshield, such as tree resin and bird droppings, can be a challenge to clean. To effectively remove these types of soiling, it is advisable to first pre-soak the area with a damp microfiber cloth. Leave the cloth on the soiled area for a few minutes to soften the dirt. Special cleaning products or a solution of water and detergent can then be used to remove the residue more easily.

For particularly stubborn stains, it can be helpful to use a cleaning stone or a special glass cleaner designed for such cases. However, be careful and do not rub too hard to avoid scratching the windshield.

Drying correctly to avoid streaks

After the windshield has been cleaned, proper drying is essential to avoid streaks or smears. Use a clean, dry microfiber cloth to wipe excess water and cleaning agent from the window. It is advisable to wipe the window in a crosswise motion to ensure even and streak-free drying. Make sure you change the cloth regularly as soon as it becomes too damp to prevent streaks from forming.

Cleaning the inside of car windows without streaks

Choosing the right cleaner

Cleaning the inside of car windows is often a particular challenge, as the wrong cleaning agents or techniques can quickly lead to streaks that cause dangerous reflections in the dark.

Techniques for streak-free interior cleaning

For streak-free cleaning of the inside of the car windows, the right technique is just as important as the right cleaning agent. Start cleaning in the upper corners and work your way towards the center in a circular motion. This method helps to remove dirt effectively without leaving streaks. It is important to change or rinse the cleaning cloth regularly to prevent the accumulation of dirt that could lead to new streaks.

How to effectively prevent soiling and streaks with a nano sealant

Regular cleaning of car windows is essential, especially in spring. Resin, bird droppings and pollen sometimes stubbornly stick to the windows. The solution: Create a protective layer with our windshield sealant. As already mentioned, the lotus effect of the nano sealant ensures that water runs off and dirt simply rinses off. In addition, dirt no longer adheres directly to the pane, which makes cleaning easier.

The advantages of nanosealing car windows

Our nano sealing creates an ultra-thin protective layer that is 500 times thinner than a human hair. This extends the cleaning cycles and saves time and money, as cleaning no longer has to be carried out as frequently. However, the actual effectiveness depends on the environmental conditions and the correct application.

  • Long durability – up to 20,000 km
  • Strong anti-adhesion properties and less insect adhesion
  • Water beads off (60+ km/h), i.e. clear view even without wipers
  • Reduces glare and light distortion at night
  • Windshield wipers have less work and are spared
  • Reduces micro scratches
  • Window easier to clean and ice easier to remove
  • UV stable with high abrasion resistance
  • Resistant to temperature fluctuations
  • Chemically resistant (ph 2 to 13)
  • Resistant to car washes and high-pressure cleaners
  • For front and side windows of cars, vans, trucks, boats and caravans
  • Apply to windshield and repeat after 6 months = 1 year shelf life
  • TÜV-tested

Easy to use, best results!

Correct preparation and application are crucial for effective windshield sealing. The most important steps are summarized here:

  1. Optimal conditions: Application should take place at temperatures between +5°C and +20°C. Avoid application below +5°C, above +30°C and in rain or strong sunshine.

  2. Thorough cleaning:

    • Clean Thoroughly clean the windshield to remove all dirt and grease residues. Dirt and water droplets often collect on the edge of the windshield in particular.
    • After cleaning, rinse the window again with water and dry it with a clean microfiber cloth.
    • The cleaning time should be at least 5 minutes, as a clean window improves the effectiveness and durability of the sealant.

  3. Preparation for sealing:

    • Put on the enclosed protective gloves to avoid fingerprints on the glass.
    • Use the alcohol pre-cleaning cloth from the packaging to additionally degrease the pane. Work quickly, as the cloth dries out after about 2-3 minutes.

  4. Application of the sealant:

    • Use the sealing cloth to apply the sealant to the windshield. Start with the central areas and seal the edges last to avoid dirt transfer.
    • Allow the sealant to dry for between 5 and 30 minutes, depending on the temperature.

  5. Post-processing:

    • After drying, polish the windshield with the enclosed microfiber cloth. This helps to remove milky or foggy residues and maximize the clarity of the seal.

  6. Curing:

    • It takes around 10 hours for the sealant to cure completely.
      However, the vehicle can be used again after just one hour. Avoid using the windshield wipers for at least 10 hours after application to ensure maximum durability of the sealant.

The most common mistakes when cleaning car windows and how to avoid them

Use of incorrect cleaning agents

A common mistake when cleaning car windows is using the wrong cleaning agent. Many people resort to aggressive chemicals in the hope of being able to clean better. However, such products can damage the pane and release harmful vapors that can affect your health. It is important to use special glass cleaners that are suitable for car windows and do not contain abrasive substances. These are not only gentler on the windshield, but also safer for the environment and your health.

It is also advisable to refrain from using household cleaners that are not designed for glass surfaces. Such cleaners can leave behind residues that are difficult to remove and impair visibility. Choosing the right cleaning agent is crucial to prevent damage and ensure effective cleaning. By relying on specialized products, you can ensure that your car windows remain free of streaks and streaks while protecting the environment and your health.

Too much pressure when wiping

Another common mistake when cleaning car windows is to apply too much pressure when wiping. Rubbing too hard can not only cause scratches on the glass surface, but also make existing streaks worse. It is important to wipe gently and change the microfiber cloth regularly to avoid streaking. The aim is to gently pick up and remove dirt without damaging the surface.

Neglect of the wiper blades and window seals

Neglecting the wiper blades and window seals is another mistake that is often made when cleaning car windows. Dirty wiper blades can leave dirt and streaks on the freshly cleaned windshield, while damaged seals can lead to leaks and thus to water stains and dirt deposits in the interior. It is therefore important to check these parts regularly and to clean or replace them if necessary.
