Copper Care Guide

Caring for Your Copper Vessel

Your THE CUIVRE vessel is crafted from 99.98% pure copper — a living material that develops a natural patina over time. A little daily care keeps it performing beautifully for years.

Daily Use

• Fill your vessel with water each evening and let it rest overnight (6–8 hours). This is when the copper's natural properties work best.
• Drink the water in the morning on an empty stomach for the full benefit of the ritual.
• Empty and rinse the vessel after use. Do not store water for more than 8 hours.

Cleaning

• Rinse with warm water after each use.
• Once a week, clean the interior with a mixture of lemon juice and coarse salt or lemon juice and baking soda. Shake well, rinse thoroughly.
• Do not use soap, as it can leave a residue that affects taste.
• Do not put your copper vessel in the dishwasher.

Patina & Polish

• Over time, your vessel will develop a warm patina — this is natural and does not affect its properties.
• To restore the original shine, rub the exterior with a cut lemon dipped in salt, then rinse and dry immediately.
• Dry thoroughly after each cleaning to prevent water spots.

What Not to Store

• Only store plain water in your copper vessel. Avoid citrus juices, milk, or carbonated drinks — acidic liquids can cause excessive copper leaching.

Storage

• Store in a cool, dry place away from direct sunlight when not in use.
• Keep the lid on to prevent dust from entering.
