COOKER HOB CLEANING AND MAINTENANCE
The glass-ceramic surface must be cleaned after every use, as
any remaining small stains will burn on the hot surface.
For ordinary maintenance purposes, use special detergents that
form a protective film against dirt.
Before every use of the hob, wipe away any dust from the glass-
ceramic surface and clean any dirt on pot bases, as it may
scratch the cooking zone (Fig. 1).

Warning: do not use steel wool sponges or abrasive detergents
that may scratch the surface. Aggressive sprays or unsuitable
detergents may also damage the surface (Fig. 1 and Fig. 2).
The signs on the hob surface may fade due to the use of
aggressive detergents, steel wool sponges or dirty pot bases
(Fig. 2). Remove the smaller stains with a damp sponge then

dry the pot thoroughly (Fig. 3).
Water stains can be eliminated using a vinegar solution which,
however, should not be used on the hob frame (of some models)
as it may lose its lustre. Do not use aggressive detergents or
sprays to remove limescale (Fig. 3).
Stubborn dirt can be removed using detergents specially
formulated for glass-ceramic surfaces. Follow the suggestions of
Fig. 3
the detergent manufacturer.
Be careful not to leave any detergent residues on the surface, as
these may damage the glass-ceramic surface (Fig. 3).
Stubborn dirt or burnt dirt must be removed with the aid of a
scraper. Make sure that the plastic scraper handle does not
come into contact with the hot cooker hob (Fig. 4).

Be careful not to harm yourself when using the scraper! Sugar
or foodstuffs with high sugar content may cause permanent
damage to the glass-ceramic surface (Fig. 5): for this reason,
any sugar residues must be immediately removed from the
glass-ceramic surface (even if still hot) using a scraper (Fig. 4).
Any change in the colour of the glass-ceramic surface does not
influence the operation or stability of the surface itself. The
colour change arises from the use of copper or aluminium pots,

or food residues on the pot base, and is very difficult to
eliminate.
Warning: all the above-mentioned defects are of an aesthetical
nature and do not directly influence the appliance's operation.
They cannot be solved by activating the warranty.
