  • Tea infuser is not included.
  • After boiling, pour out all remaining water and allow the residual heat to dry the inside of the kettle naturally.
Care & Warnings
  • This kettle has an uncoated cast iron interior, which may naturally develop rust over time.
  • Do not leave water inside the kettle after use. Empty it completely and allow the remaining heat to dry the interior.
  • Do not use soap or detergents. Rinse with warm water only.
  • Store the kettle in a dry, well-ventilated place.
  • Avoid heating an empty kettle.
  • Small amounts of surface rust are normal and are generally not a problem as long as the water remains clear.
  • If rust begins to appear, boiling brewed tea in the kettle may help reduce further rust formation, as the tannins in tea can provide a natural protective coating.
