Dust brushes made of soft, hand-pulled goat hair are particularly suitable for sensitive, smooth surfaces such as pianos, glass tables, etc. Please only wash the hair with lukewarm water and a mild soapy solution if it is very dirty. After washing, gently squeeze out in a towel and leave to dry in the fresh air or lying on its side at room temperature. Then comb out gently with a metal comb. This way they can last a lifetime!
