Windshield scratches from worn wiper blades are one of the most common issues drivers face. The question is always the same: can I fix this myself, or do I need a professional? Here is our honest answer.

DIY Kits: What They Can and Cannot Do
DIY glass scratch removal kits typically include cerium oxide powder and a felt polishing wheel. They can work for very light surface scratches, but they have significant limitations.
- Effective only on scratches you cannot feel with your fingernail
- Risk of creating optical distortion if applied unevenly
- Typically require 2-4 hours of manual work per small area
- Cost: €20-50 for a kit, but results are often inconsistent

Professional Glass Polishing
Professional glass polishing uses specialized equipment and compounds that work at a different level than DIY kits. The key difference is precision and consistency.
| Equipment | Professional-grade rotary polisher with glass-specific pads and cerium oxide slurry. |
| Process | Controlled, measured passes that remove material evenly without creating distortion. |
| Result | Complete scratch removal with optical clarity maintained. Saves €300-500 vs windshield replacement. |

When to Choose Each Option
| DIY | Hairline surface scratches on side windows where optical perfection is less critical. |
| Professional | Wiper scratches on windshield, deep scratches you can feel, or any scratch in the driver's line of sight. |
| Replace | Cracks, chips that have spread, or damage to the laminated layer of the windshield. |
