CLEANING AND MAINTENANCE
DESCALING
Due to minerals in water, deposits may form on the base of the
kettle and cause discolouration. To get the best performance from
your kettle, descale it from time to time. Frequency will depend on
the hardness of your water and how often you use the kettle. You
can either follow the directions using a commercial descaler, or use
vinegar and water and follow the directions below:
1. Fill the kettle with enough white vinegar to cover the bottom by
about 1.5 cm. Heat the vinegar to a boil.
2. Repeat with fresh vinegar until all deposits are removed.
3. When the descaling process is complete, empty the kettle and
rinse several times with clean water.
