Here are some suggestions for cleaning and maintenance:
Cleaning: Hand wash with cold water, add a small amount of neutral detergent, avoid rubbing or machine washing. Gently soak and press lightly to clean, do not use bleach.
Drying: Lay flat on a dry towel to air dry naturally, avoid direct sunlight or high temperature drying to prevent fading or deformation.
Maintenance: Remove dust regularly with a soft brush, fold neatly or hang in a dry place when storing, avoid compression. Keep dry and away from moisture and sharp objects.
