**Pre-Wash Treatment**
For the first wash of new quilt sheets, use mild soapy water. Avoid vigorous scrubbing to prevent the print from coming off.
When machine washing, select the gentle cycle and keep the water temperature below 30℃ to avoid fiber shrinkage.
**Detergent Selection**
Use a neutral detergent. Do not use products containing bleach or fabric softener, as these can damage the fiber structure.
You can add a small amount of white vinegar (500 ml per liter of water) to soften the fibers and reduce detergent residue.
**Air Drying and Shaking**
Lay flat to dry in a cool, well-ventilated place, avoiding direct sunlight to prevent fading.
After drying, gently pat or shake the quilt to help the fibers regain their fluffiness.
**Special Material Treatment**
For cotton quilts, regularly air and shake them to maintain their softness.
For synthetic fiber quilts, air them once a month and no special care is required.
Note: The fluffiness may decrease slightly after washing, but it can be restored to the maximum extent with proper care.
