- 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.
