To prevent cracks in the horn cup, it should be dried upside down after use, not exposed to moisture for extended periods, and regularly rubbed with vegetable oil (e.g., olive oil). Avoid dishwashers, extreme temperature fluctuations, and contact with alkalis or harsh cleaning agents. Cold, non-carbonated beverages, such as water or juices, are safe for consumption; however, liquids above 60°C and highly carbonated drinks should be avoided to protect the material and the seal.
