The most common causes of scratch damage on glass are:
- Scraper damage – where misuse of a scraper has caused the debris to create small scratches across a pane of glass
- Trowel damage – where a dull metal edged tool has been used to remove cement or render from glass. Unlike the scraper the tool causes the damage
- Brillo pads – commonly found on shop fronts and restaurants where abrasive pads have been used to clean stubborn stains from glass.
- Sandpaper scratches –caused when decorators use sandpaper or sanding blocks to prepare frames for painting or staining. Unfortunately because the scratches are close to the edge of the glass the only way to repair the glass distortion free is to remove the glass from the frame. Because of this in most cases replacement of the glass is usually the cheaper option.
