1. Regular inspection: Check the edge seal every 6 months and address any cracks promptly.
2. Avoid extreme environments: Install a sunshade film to reduce direct UV radiation. Chemical workshops should use acid-resistant glass.
3. Professional cleaning: Use a neutral detergent and avoid scratching with steel wool or other hard objects.
Note: If the glass becomes noticeably blurry, has bubbles covering more than 5% of its surface, or a single crack is longer than 30cm, it should be replaced even if the warranty period has not expired.
