There are two maintenance methods for printed fabrics:
Saltwater soaking method: It is most suitable for the fading problem of colored clothes. If there is a slight color fading, you can soak it in light salt water for ten minutes before each washing.

Anti-drying method: Most fabrics should not be directly irradiated by the sun, because ultraviolet rays are the main culprit of fading clothes, so they should not only be dried in reverse, but also in a place that avoids the shade and ventilation as much as possible.
