What is the method to identify the production date of vehicle glass?

[MacMakayla]

Identifying the production date of vehicle glass involves the following steps: 1. Check the code located at the bottom left or right corner of the window glass; 2. The numbers represent the year, while the dots represent the month. Dots in front of the number indicate the first half of the year—subtract the number of dots from 7 to get the month. Dots behind the number indicate the second half of the year—subtract the number of dots from 13 to get the month. Methods for maintaining vehicle glass include: 1. Use glass cleaner appropriately; 2. Apply a protective film to the car glass; 3. Purchase glass insurance for the vehicle; 4. Thoroughly remove dirt from the car glass; 5. Regularly replace the rubber seals.
