Drinking water stored in a copper vessel for 8 hours can provide numerous health benefits. Copper possesses antimicrobial properties and antioxidant effects that can enrich water with beneficial ions, potentially enhancing overall well-being. Here are some eco-friendly methods to clean and maintain your copper vessel for optimal benefits:

1. Interior Cleaning: To clean the interior, consider using a glass tumbler or any other non-metallic container. Prepare a solution of lime, salt, and warm water, and let it sit in the vessel for a few minutes. Rinse thoroughly with regular water, avoiding abrasive brushes.

2. Exterior Cleaning: Protect the lacquer coating by wiping the exterior with a soft cloth. Stubborn stains can be tackled with natural remedies such as tamarind, cleaning powder, or liquid gel. Avoid using scrubbers or harsh chemicals, as they may damage the vessel's surface.

Remember, minor dents or a faint smell of lacquer won't compromise the vessel's effectiveness. While enjoying the benefits, refrain from storing anything other than water and avoid exposing the vessel to extreme temperatures or harsh cleaning methods. By following these simple steps, you can maintain the health benefits of your copper vessel in an environmentally friendly manner.
