To neutralize the natural odor of the horn cup, thorough cleaning with lukewarm water and mild dish soap or special cleaning tablets like Kukident is recommended. Home remedies such as baking soda or briefly rinsing with vinegar water can also help, but hot liquids must be strictly avoided to prevent damage to the material. The cup is less suitable for use with carbonated beverages, as the carbonation and the acid it contains can, over time, attack the natural horn or any existing inner coating, making it brittle.
