First, you will mix the lemon with water and bring it to a boil. After the mixture rests and becomes cool, you pour it out, you are also getting rid of the scales.

Some solutions can contaminate your electric kettle after descaling with them. Lemon juice is perfectly safe.

This should get rid of hard water residues or stains. Shred or cut the lemon into smaller pieces and add them to the kettle.
  • Water. Add about 500ml of water to the kettle without filling it to the top. You only want the water mixture with the lemon juice to be enough to cover the elements at the bottom. You can fill the kettle halfway.
  1. Bring the mixture to a boil

Your mixture is now lemon water. Bring it to a boil for the acid to get to work faster. The water should reach boiling level depending on the heating speed or wattage of your kettle.

Turn off the kettle, disconnect it from the power source and allow it to sit for at least 30 minutes or overnight so that the lemon juice can dissolve the limescale. Leaving it overnight is preferable for the acid to remove all limescale.
