You can also use your copper tumbler to drink water at any time. It is recommended to drink the water at room temperature. The copper container should not be stored in the refrigerator. Copper gets darker over time. The copper container needs to be cleaned from time to time. Use lemon juice or tamarind to rub utensils. Leave to work for a few minutes and wash with water.
