Cleaning and care
Ceramic surface
42
Wipe all coarse soiling off using a damp cloth. Stubborn
soiling may need to be removed with a shielded scraper
blade.
Then clean the hob with a suitable ceramic and stainless
steel hob cleaner (see "Optional accessories") applied with
kitchen paper or a clean cloth. Do not apply cleaner whilst
the hob is still hot, as this could result in marking. Please
follow the manufacturer's instructions.
Finally, wipe the hob with a damp cloth, then polish with a
soft, dry cloth. Ensure that all cleaner residues are removed.
Residues can burn onto the appliance the next time it is used,
and cause damage to the ceramic surface.
Spots caused by limescale, water and aluminium residues
(spots with a metallic appearance) can be removed using a
ceramic and stainless steel hob cleaner.
Should any sugar, plastic or aluminium foil spill or fall onto
a hot cooking zone while it is in use, first switch off the
appliance. Then carefully scrape off all the sugar, plastic or
aluminium residues from the hob whilst they are still hot using
a shielded scraper blade. Take care not to burn yourself.
Allow the appliance to cool down, and then clean as
described above with a suitable ceramic and stainless steel
hob cleaner.
