Cleaning and care
■ Never use sharp or abrasive agents!
It is sufficient to clean with a damp
cloth and a little washing-up liquid
after usage. Wipe dry.
■ Incrustation due to boilied over foods
are best presoftened with a wet
cloth. Then remove them with a glass
scraper. Sugar and melted plastic
should be removed while the cooking
area is still hot.
■ Clean the glass-ceramic cooking area after every use. Always keep the sen-
sor keys clean, since soiling could be detected as finger contact by the
aplliance. Immediately remove soiling. Never put anything (pans, tea-towels
etc.) on the sensor keys! If food boils over onto the sensor buttons, we ad-
vise you to activate the emergency switch.
■ Care for your glass-ceramic cooking area once a week. Regular care builds
up a protective layer and also eases day to day cleaning. Please follow the
instructions of the cleaner or cleanser manufacturer concerned. Even heavy
soiling can be cleaned with a cleanser and enough water. Wipe dry with a
cloth.
■ Do not use the cleaning agent on the grill surface as the protective film
would come into direct contact with food. We recommend you to rub down
the grill surface with half a lemon or lemon juice. Any slight dirt marks from
protein, e.g. from meat, is removed and the grill surface shines again.
