1. The sleeve should be covered when used. If it has been stained, the duvet should be sent to the dry cleaner for dry cleaning, and the general fiber can be directly machine washed.

2. The fabric of the duvet is treated with anti-velvet. A small hole will also be drilled, so be careful when using it to avoid being punctured by sharp objects.

3. Choose the weather, dry the quilt in a well-ventilated place without direct sunlight, and take the best time from 10 am to 3 pm.
