Your dabba is made from brass, an alloy of copper and zinc. Like copper, brass is a living metal which develops a patina over time giving it a warmer tone with use. Some people like this aged look, while some prefer to keep it shiny and bright! Clean the dabba as and when you need to, or as a nice seasonal ritual, it's up to you!
Just like you season a cast iron pan, begin your relationship with your dabba by rubbing all over with a little coconut oil and then wipe down with a clean towel to create a protective coating. This will help prevent stains from fingerprints or food touching it, and help it patina more beautifully and evenly.
To clean your patinated dabba:
1. Make a paste of flour and white vinegar (no special ratio, you're just creating a carrier paste for the acid which helps remove the tarnish).
2. Scrub the paste onto the dabba with a soft brush, like our favorite vegetable scrubber or toothbrush. Do not use any kind of steel wool/metal scrubber!
3. Once the stain is removed, rinse with warm water and wipe dry. You may have to do this twice for tougher stains.
4. Finally, rub all over with coconut oil to seal, and wipe off with a soft towel for a smooth shine!
Note: You can also use Brasso or Flitz powder if this is process does not work.
