What are the best ways to properly clean and maintain a spirit decanter?

To properly clean and maintain a spirit decanter, use warm water and mild dish soap to hand wash it, avoiding harsh chemicals and abrasive materials. Rinse thoroughly and dry with a soft cloth to prevent water spots. To remove stubborn stains, use a mixture of water and white vinegar or baking soda. Store the decanter in a cool, dry place away from direct sunlight to prevent damage. Regularly clean and dry the decanter after each use to maintain its clarity and shine.
