After use, the horn drinking cup should be cleaned immediately by hand with running, lukewarm water and, if necessary, a mild dish soap. It must then be thoroughly dried. Storing it upside down in a well-ventilated place is ideal to prevent mold growth. To prevent cracking and keep the material supple, it is recommended to regularly rub the cup with a neutral vegetable oil or horn balm and protect it from extreme heat, direct sunlight, or radiators.
