1. The color of the backpack may fade. When cleaning for the first time, do not mix it with other items.
2. If the backpack is expensive or has some special meaning, it is recommended to send the bag to a dry cleaner for cleaning.
3. If the backpack is bright in color, it is not recommended to dry it directly in the sun, as exposure to the sun will cause the bag to fade.
4. The backpack should have become loose after washing. It is not recommended to use a drum dryer to clean the backpack in order to save time, which will shrink the backpack.
