Common Questions About Silicone Coated Wiper Blades

Cleanbro silicone wiper blades are designed with an integrated, replenishable coating system. To achieve consistent water-repellent performance, factors such as windshield condition, coating time, and vehicle age should be taken into consideration. This guide provides technical explanations and solutions to common questions, helping users and professionals maximize product performance.

Q1. Why is the coating effect not obvious?

For optimal coating performance, please ensure the windshield is deeply cleaned and completely dry before use. Set the wipers to medium speed and perform dry wiping for 3–5 minutes to form an even coating layer.

Important notes:

• Always use medium speed for dry wiping.
• Extremely slow or fast speeds may affect coating uniformity.

We recommend extending the coating time to 5–10 minutes under the following conditions:

• Ambient temperature below 15°C
• Windshield is clean but not fully dry
• Vehicles older than 5 years (Older vehicles may have reduced wiper arm pressure, requiring longer coating time)

Q2. Why does slight wiper vibration occur?

Wiper vibration can be influenced by multiple factors, especially on longer driver-side wiper blades. If there is no full-blade jumping, slight movement is generally considered normal.

Possible causes include:

• Uneven pressure distribution at the tail end of long wiper blades
• Incomplete windshield deep cleaning during initial installation
• Oil residue or contaminants damaging the coating layer
• Insufficient coating time, resulting in uneven coating formation
• Reduced wiper arm pressure on older vehicles
• Improper installation or loose adapters
• Incorrect blade size causing contact between two wipers

Q3. What causes abnormal noise?

Please check the following:

• Confirm the source and condition of the noise
• Ensure the wipers are installed correctly
• If noise occurs during blade reversal, debris or slippage may be present → Clean both sides of the windshield
• If friction noise occurs due to flattened rubber, the blade size may be too long → Replace with a shorter size
• Stubborn oil film or dust can affect initial coating formation → Always perform deep windshield cleaning during first installation

Q4. Why does water repellency weaken after long-term use?

Reduced water repellency is usually caused by dust, oil residue, or contaminants covering the coating layer.

Cleanbro silicone coated wiper blades feature a replenishable coating mechanism. If performance decreases:

• Thoroughly clean the windshield
• Perform dry wiping again to restore the coating

Normal water-repellent performance will be recovered.

Q5. Why does a temporary fog-like effect appear occasionally?

This is a temporary physical phenomenon that may occur with coated products under certain conditions.

Recommendations:

• Use intermittent wiping mode during rain
• The fog effect typically disappears within 3 seconds
• Reducing continuous wiping helps minimize motor wear

If there is a significant temperature difference between the interior and exterior of the vehicle, activating the front windshield defogging function can effectively reduce this effect.

Q6. Why does partial wiping occur?

Cleanbro silicone coated wiper blades are aftermarket consumable products, designed to fit the majority of vehicle models.

On windshields with extreme curvature (very flat or highly curved), slight partial wiping may occur due to uneven pressure distribution common to frameless wiper designs.

Solutions:

• For minor areas: gently adjust the steel strip curvature in the opposite direction of the unwiped area
• For significant issues:
  • Use one size shorter
  • Or select an alternative Cleanbro wiper model better suited to the vehicle
