What should I do if the curtains fade at high temperature?

1. First, remove the curtain from the window immediately and cut off all the hooks on the curtain.

2. Secondly, soak the curtains in warm water and add a proper amount of laundry detergent to clean them.

3. Then, after cleaning, dry the curtains in the sun.

4. Then, if the curtains have faded badly, you can try to dye them again or buy new curtains.
