Cleaning and Care Instructions for your Copper Flask

🧘 Therapeutic Benefits of Drinking from a Copper Flask

For centuries, Ayurvedic practices have revered copper for its powerful health benefits. When water is stored in a copper flask (for at least 6–8 hours or overnight), it becomes infused with trace amounts of copper, creating what is known as “Tamra Jal”. Here are some believed benefits:

  • Boosts Immunity – Copper has antimicrobial, anti-inflammatory, and antioxidant properties.

  • Supports Digestion – Drinking copper-charged water on an empty stomach may help cleanse the digestive tract.

  • Balances the Three Doshas – According to Ayurveda, copper helps balance Vata, Pitta, and Kapha.

  • Promotes Healthy Skin – Copper is known to aid in the production of melanin, which supports healthy skin regeneration.

  • Slows Aging – Its antioxidant power may help reduce fine lines and wrinkles over time.


🧼 How to Clean Your Copper Flask

To maintain both the beauty and health benefits of your copper flask, follow these simple steps once or twice a week:

Quick Natural Cleaning Method

  1. Lemon and Salt Scrub

    • Cut a lemon in half, sprinkle salt on it, and rub it all over the flask.

    • Alternatively, make a paste of lemon juice and salt, and scrub using a soft cloth or sponge.

  2. Rinse with Warm Water

    • Rinse thoroughly to remove all residue.

  3. Dry Immediately

    • Use a soft cloth to dry the flask to prevent water spots or tarnishing.

❗ Avoid:

  • Harsh chemical cleaners

  • Dishwashers

  • Steel wool or abrasive scrubbers

Why this method?
Lemon is naturally acidic and breaks down oxidation, while salt acts as a gentle abrasive. This helps keep your flask clean without damaging the metal’s integrity.


⚠️ Blackening or Tarnishing – Why It Happens & What to Do

Blackening or dark spots on copper are completely natural and a result of oxidation, especially when exposed to:

  • Air and moisture

  • Certain acidic or salty water

  • Lack of regular cleaning

This is not a defect—it’s a sign of authentic copper reacting to its environment.

🛠 How to Manage It:

  • Use the lemon + salt method above to remove tarnish gently.

  • For deeper stains, soak the flask in a mixture of vinegar and salt for 10–15 minutes, rinse, and dry.

🌿 Pro Tip:

Apply a thin layer of coconut oil or beeswax to the outside of the flask (not the inside) to protect it from oxidation and keep it looking shiny.


🔁 Additional Care Tips:

  • Store only still, room-temperature water in your flask. Avoid carbonated drinks, juices, or hot beverages.

  • Do not refrigerate or freeze your copper flask.
