• Before using the ceramic glass module, the surface
must be cleaned, using a damp cloth to remove dust
or food residues. The ceramic glass surface should be
cleaned regularly with a soultion of warm water and a
non-abrasive detergent.
Periodically, special products
will need to be used to clean
the surface. First, remove all
food buildup or grease with a
cleaning scraper, e.g.
(not supplied).
Clean the cooking surface when
it is still warm with a suitable
cleaning product (such as the
one in the Solutions product line available from any
After-Sales Service Centre) and paper towels. Then rub
with a damp cloth and dry. Aluminum foil, plastic items,
objects made of synthetic material, sugar or foods with
a high sugar content that have melted onto the surface
must be removed immediatley with a scraper while the
cooking surface is still hot.
Special cleaning products for
ceramic glass surfaces form

which fights diry buildup. This
also protects the surface from

cleaning products under any
circumstances. This holds true for chemically aggressive
cleaners, like oven sprays and stain removers.
• Stainless steel can be marked by hard water that has
been left on the surface for a long time, or by aggressive
detergents containing phosphorus. After cleaning, rinse
and dry any remaining drops of water.
! It is not necessary to remove the pan supports in order to
clean the hob surface. Thanks to the support system, simply
lift and hold the pan supports or rotate them until they rest
against a rear support.
Do not place the hot grids on top of the glass cover (if
applicable), otherwise the rubber plugs on the glass
may be damaged.

To remove all types of stains just wipe with a smooth cloth,
wet with hot water.
For stronger stains, we recommend the use of common
detergent for dishes, with a cloth dampened with hot water,
to ensure a perfect cleaning result.
Is not recommended to use rough sponges and abrasive
products as they may damage the special treatment.
