Description
Ayurveda recommends a simple, practical and effective method of drinking water in its most holistic way - drinking water from a copper cup. To make copper water, pure water in the copper cup and leave it overnight. When water is kept for a specific time period in the copper glass, it kills the undesirable bacteria and viruses and the resultant water gets charged with the health benefitting qualities of the copper.
Drink it as soon as you get up in the morning. You can also use your copper cup to drink water from it at all times. It's recommended to drink the water at room temperature. The copper cups should not be stored in fridge. Copper darkens naturally over a period of time. Care Tips:-

 Clean your copperware by hand and avoid dishwasher as the detergent can cause oxidation leading to permanat damage.
A simple, soft cleaning liquid on soap base, hot water and a soft washing cloth is best for daily use. 
Use Pitambri Shining Powder for cleaning the copper utensils. More effective than traditional cleaners like tamarind, lemon and buttermilk. Completely safe and gentle on hands.
The copper cup requires cleaning from time to time.
