Maintenance knowledge of duvet
1, the quilt cover should be used. If it has been polluted, the duvet should be sent to the dry cleaner, and the ordinary fiber quilt can be directly machine-washed.
2. The fabric of the duvet will drill a small hole after down-proof treatment. Be careful when using it to avoid being cut by sharp tools.
3. Choose good weather and hang the duvet in a well-ventilated place without direct sunlight. The best time is from 10 to 3 pm.
