• 30 ml (2 tablespoons) white vinegar
  • 250 ml (1 cup) water

  • 1.) Simmer the water and vinegar in your kettle or teapot and leave for 30 minutes.
  • 2.) Once the calcium deposits have loosened, use steel wool to remove them.

  • Editor’s Note: This method only works well if you can scrub the deposits with steel wool. For sealed kettles and coffee makers, use full strength vinegar and run it through 2-3 times. By removing the scale that accumulates in your kettle, teapot or iron, you will increase its energy efficiency.
