There are two types of hotel duvets. One is down duvet and the other is polyfiber comforter or quilt.
Drying or machine washing is generally not recommended for the washing of duvets, as these two washing methods can damage the fabric or filling quality of the quilt. Therefore, the duvet is best washed with water and hand.
If it is only partially contaminated, it can be washed partially. If it is necessary to wash it all, it can be washed as follows:
Soak the duvet in cold water for 20 minutes to allow the duvet to be fully wet inside and outside. Dissolve the detergent (neutral, non-bleaching ingredients) in warm water at 30 degrees (Note 1: low temperature), then place the duvet in it for 15 minutes, then gently brush with a soft brush. Rinsing should also use warm water, which can help the detergent to be fully dissolved in the water, and the duvet can be rinsed more cleanly. Pay attention to the thorough rinsing and no detergent residue. After rinsing, the quilt will be folded evenly (or three folds), and the water will be squeezed out of the core while being rolled. Use the machine to dehydrate and wring out carefully. It can be dried first with the dryer low temperature (note 2: still low temperature),so that it helps the down to a fluffy and soft texture without damaging the quilt.
The polyfiber can be water washed or dry-cleaned. When washing, it is also recommended to use water washing (machine wash, hand wash).
