To remove light dust or dirt, use a clean dry cloth. Avoid using soap, oils, abrasive cleaners, furniture polish, varnish, or ammonia-based products, as they may damage the material and finish. If the hat becomes wet, gently blot excess moisture with a soft dry cloth and allow it to air dry naturally at room temperature.
Do not wash or submerge in water. Store in a cool, dry place to preserve shape and detailing.
