Cleaning and care
Should any sugar, plastic or
aluminium foil spill or fall on to 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 cooking zone to cool down,
and then clean as described above
with a suitable proprietary ceramic hob
cleaner.

Appliances with aluminium frames
(see data plate) are prone to
scratching, alkali and acid damage.
Take great care when cleaning the
aluminium frame. Do not use cleaning
agents for stainless steel or descaling
agents on aluminium surfaces. Soiling
should be wiped off as soon as
possible after using the appliance. If
the soiling is left for a long time it can
have a damaging effect on the
aluminium surfaces. Intensive cleaning
with proprietary ceramic cleaners can
cause the frames to take on a shiny
appearance.
