How scratches happen
Grit trapped under a pad or squeegee, dragged across the pane. In a dusty coastal environment this is a constant risk and the reason method matters.

PreservationFacade Glass: Cleaning It Without Scratching It
Scratched glass cannot be cleaned back. It is one of the few outcomes in this trade that is genuinely permanent.
What matters, and why.
The method
Copious water first to float the grit off, then clean tooling, then the blade. Never a dry pass and never an abrasive pad on glass.
Coatings
Some glass carries a low-emissivity or solar coating on one face. Abrasive methods destroy it and the damage is visible in raking light.
Hard water spotting
Fresh mineral deposit dissolves with the right acid and dwell time. Glass spotted for years is etched, and cleaning improves it rather than clearing it.
If this is something you would rather hand over, our specialist cleaning and restoration is scoped at an inspection and confirmed in writing before any work begins. We will also tell you when a job does not need us.
Questions
Answered plainly.
Sometimes, by cerium oxide polishing. It is a separate slow job and occasionally replacement is the cheaper answer.
Yes, and it is often the safest option because it minimises contact.
More often than inland. Salt bonds harder the longer it is left, so the interval matters more than the method.
