Cleaning: Gently wipe surface stains with a damp cloth, or hand wash using cold water and mild detergent. Avoid prolonged soaking to prevent shape distortion.
Drying: Air dry naturally, reshape and lay flat or use supports (such as a hat stand) to maintain shape, avoid high-temperature drying.
Maintenance: Avoid folding when storing, keep in a well-ventilated and dry place to prevent mold. Regularly remove dust with a soft brush.
