How to descale a kettle like a pro…

Where lime deposits

Traditionally, the element in the kettle was always exposed and in contact with the water, so that lime scale was one of the biggest causes of kettle failure.

Nowadays in our kettles the element is usually hidden behind a metal base plate, which reduces the risk of damage to the element and extends its life. However, this does not mean that lime is not a problem.

Metal kettles can still be covered with lime on the inside and on the base plate, which, when it dissolves, leaves unsightly lime particles in the water. Plastic boilers are made of polypropylene, which does not attract lime deposits, but the metal base plate does. Kettles with built-in filters prevent limescale particles from getting into your drink, but they do not prevent limescale deposits from forming.

If you regularly decalcify your kettle,

  • does this help to keep the inside of your kettle clean

  • it extends the life of your kettle

To decalcify a kettle, you can use any type of decalcifying agent based on citric acid or, for example, white table vinegar.

If you use a descaling agent from your supermarket, follow the instructions on the packaging.

Descaling a kettle with vinegar

  1. Fill the kettle with water up to three quarters of the maximum level and bring the water to the boil.
  2. After turning off the kettle, add white vinegar (8% acetic acid) to the maximum level.
  3. Empty the kettle and rinse the inside thoroughly.

    empty the kettle and rinse it again with fresh water.

  4. Repeat the process if there is still some lime in the kettle.

  1. Put 2 tablespoons of vinegar essence in your kettle and then add a cup of clear water.
  2. Stir the mixture with a spoon and then boil it up.
  3. Let this mixture work for about 30 minutes after boiling. During this time, the lime deposits should be completely dissolved.
  4. Now rinse the kettle well with clear water.
  5. If there are more lime deposits in your kettle, repeat the procedure.

Descale water boiler with citric acid

  2. Fill your kettle at least so far that all visible lime edges are covered.
  3. Heat briefly and leave to take effect for a maximum of 30 minutes.
  4. Rinse thoroughly with clean water.

You can always proceed in the same way when using these lime solvents.

  2. Then bring the cleaning liquid to the boil.
  3. Leave the liquid to work for about 30 minutes.
  4. Then pour the descaler into the drain and clean the appliance thoroughly with clean water.

Frequency of decalcification:

Regular descaling extends the life of the kettle and limits the risk of premature failure.
For normal use (up to 5 times a day) the following decalcification frequency is recommended:

  • Once every 3 months if you use soft water (up to 18dH).
  • Once a month if you use hard water (more than 18dH).

Contact your local or regional water authority for information about the hardness of your tap water. If you use the kettle more than 5 times a day, you may need to descale it more often.
