Professionals employ various techniques to effectively address scratches on glass windows. For fine scratches, we may use a buffing pad and a small amount of polishing compound to polish the scratches away. For deeper scratches, we might use very fine abrasive pads, reducing the abrasive level until the scratches are minimized, at which point we can polish. Professional methods can help rejuvenate the appearance of glass windows by effectively addressing different types of scratches.
