What are the cleaning and maintenance methods for three-chamber duck-down pillows?

1. Cleaning methods and steps
Use a vacuum cleaner (equipped with a soft brush head) to clean the dust on the surface of the three-chamber duck-down pillow regularly to avoid the accumulation of fine down fibers in the gaps between the chambers. For local stains, spray white vinegar and water (1:3 ratio) on the stains, let it stand for 10 minutes, then wipe it gently with a soft cloth, then wipe it with clean water and dry it in the shade (suitable for oil stains and sweat stains).
For deep cleaning, the chambers need to be processed separately: soak the upper duck-down chamber in cold water, and then use a neutral detergent to gently press and wash it to avoid rubbing and causing the down to break. The middle support layer (such as memory foam/feather silk cotton) cannot be washed with water, and needs to be wiped with a damp cloth dipped in baking soda solution to remove sweat stains and sebum.
The removable fiber layer of the bottom fiber layer can be machine washed separately, and the water temperature is ≤30℃ to avoid high temperature causing fiber hardening.

2. Drying precautions
The duck down layer needs to be laid flat to dry (avoid exposure to the sun), pat it once an hour to restore its fluffyness, or dry it at low temperature (≤50℃). The memory foam layer can be placed in a cool and ventilated place to dry, and exposure to the sun or drying is strictly prohibited to prevent deformation. When it is half dry, pat the down layer with a hanger to make the down evenly distributed; the memory foam layer needs to be manually adjusted in shape.

3. Daily maintenance suggestions
Use a dehumidifier to treat the bedroom every month (humidity ≤50%), or place a bamboo charcoal bag under the pillow to absorb moisture. Turn the pillow over every week to make the force of each cavity even and avoid local collapse. Pat the pillow after getting up every day, especially the duck down cavity. If mold occurs during use, it needs to be disassembled and processed separately, the down layer should be sent to professional dry cleaning, and the memory foam layer should be wiped with alcohol and disinfected with ultraviolet light.
