Scratches on glass aren’t just a cosmetic issue. At night, oncoming headlights scatter across them and create glare right in the driver’s field of view. In the rain, the problem doubles. For a vehicle carrying dozens of passengers, that’s a safety issue.

Where they come from

Worn wiper blades: the most common cause. Once the rubber hardens or tears, the metal arm scores the glass on every pass, leaving a characteristic arc.
Cleaning with the wrong materials: dry-wiping dust off the glass acts like sandpaper.
Scoring and vandalism on side windows — a frequent issue on urban and school buses.
Sand and grit from prolonged exposure.

How we work

Restoration is done through gradual sanding and polishing of the surface, using specialised materials and controlled pressure. The process removes a minimal layer of glass — just enough to make the scratch disappear without creating optical distortion.

This is the critical part of the job: excessive or uneven polishing creates a “lens” effect at that spot — a distortion of the image, which is worse than the original scratch. That’s why this work requires experience, not just the right tool.

What can and can’t be restored

Surface to moderate-depth scratches are fully restored. Deep scoring — the kind you can clearly feel with a fingernail — has limits: it can be significantly reduced, but fully eliminating it would require removing so much material that it would cause distortion.

We’ll tell you upfront what result is realistic for your specific damage, before any work begins.

Cost

Scratch removal costs significantly less than glass replacement — especially on large bus windscreens. For a fleet with multiple vehicles, the difference is substantial.
