Favourite this Product The material may also show some stains. These are natural properties of copper and do not negatively affect drinking from a copper object. Pure copper reacts with oxygen, water, and residues in water, such as sulfur. It actually means that the object has a high copper content and works well to purify the water. The discoloration of the inside is not harmful. If the discolorations become too severe, you can clean the bottle, jug, water tank, or cup. Copper vessels are only suitable for water, not for milk, citrus juices, and acidic liquids. Do not wash in the dishwasher. Clean with natural soap, a soft sponge, and water at room temperature. Do not expose to direct sunlight. Our unique copper bottles, jugs, water tanks, and cups have been handmade in India for centuries. Because it is handmade, each item is unique and may differ slightly from the photo. There may also be irregularities in the material: this is part of the natural properties of copper.
