Cleaning and Care 4.6 Descaling Regularly removing any scale deposits inside the kettle will prolong your kettle's life, and ensure maximum performance and energy savings. The kettle can be descaled using specific descaling products. Improper use Risk of damage to the appliance • Do not use descaling products for cleaning bathrooms or kitchens, or scented products. Leave the descaling product to act, then rinse thoroughly. Then boil at least two full kettles of water, disposing of the boiling water safely, to remove any residue of the product before use. Alternatively, you can use common household vinegar. Proceed as follows: 1. Fill the kettle with water (1 liter/4 cups) and boil it. 2. Add the white vinegar (from 0.1l/0.42 cups to 0.5 l/2 cups depending on the amount of scale). 3. Leave it to act overnight. 4. Empty the kettle. 5. Fill the kettle with water and boil it. Empty the kettle, disposing of the water safely. Repeat this operation at least twice. Tips and suggestions for the user • Scale build-up can cause the kettle to switch off during use before the water has boiled. Boiling times could also be increased. • If the kettle is used daily, or if it becomes more difficult to pour out the water, descale the kettle and filter more frequently. • In some regions the water is harder, and therefore, it could have a cloudy appearance and leave residue on the walls of the kettle. In this case, clean the inside of the kettle more frequently or use purified/softened water. 20
