Wool felt works can be cleaned， but must comply with the following requirements：
　　● Wash with cold water， do not bleach.
　　● Choose a neutral wool cleaner marked with a pure wool logo and no bleach.
　　● Hand wash alone， do not use the washing machine， so as not to undermine the appearance.
　　● When cleaning gently by hand， the dirtier part scrub only gently， do not brush with a brush.
　　● Use shampoo plus rinse solution cleaning， can reduce the pilling phenomenon.
　　● After cleaning， hang in the ventilated place to dry naturally， do not insolate. For drying， please use low temperature drying.
