To ensure the 1.25-liter drinking horn remains in good condition, it should be cleaned immediately after each use with lukewarm water, a small amount of mild dish soap, and a soft bottle brush, and then thoroughly dried. To keep the natural exterior supple and maintain its shine, it is recommended to occasionally rub the horn with a little vegetable oil. The horn should never be cleaned in the dishwasher or soaked in water for extended periods. Hot, highly acidic, or carbonated beverages should also be avoided to prevent damage to the food-safe inner lining. Any odors that may develop can be eliminated by cleaning with denture cleaning tablets.
