The horns used in the production of these cups come from various cattle breeds or water buffalo, with the horn being a natural byproduct of meat production. To clean them, the cups should be rinsed immediately after use with lukewarm water, a small amount of mild dish soap, and a soft brush, then dried thoroughly. To prevent cracking, the material should not be placed in the dishwasher or soaked in moisture for extended periods. Occasional treatment with a neutral vegetable oil is also recommended. To combat unpleasant odors, cleaning with denture cleaning tablets, allowing them to soak for about an hour, is recommended.
