Hat care and storage are essential. After removing a hat, do not just toss it around; hang it on a coat rack or a hook. Avoid placing heavy items on top to prevent deformation. Over time, hats accumulate oil, dirt, and grime on the inside and outside, which should be cleaned promptly. The hat lining can be removed, washed, and then stretched back on to prevent sweat and dirt from becoming damp and moldy, which can shorten the hat's lifespan. Regularly brush off the dust on the hat. For stubborn dirt and grease on the hat surface, use a soft brush dipped in warm soapy water to gently scrub, then rinse with clean water.

When cleaning a hat, find a round jar or porcelain bowl the same size as the hat, place the hat on top and then clean it to prevent distortion. When storing a hat: brush off the dust, wash away the dirt, let it dry in the sun for a while, then wrap it in paper and place it in a hat box. Store it in a well-ventilated and dry place. Additionally, place a desiccant inside the storage box to prevent moisture. Cleaning a hat requires special attention; some cannot be submerged in water (such as feather, sequins, or hats with lining paper). If the hat is made of cotton, it can be washed, but if it has a paper lining, it should only be wiped and not washed, as washing it will bring bad luck. Due to its three-dimensional shape, it is taboo to use a washing machine.
