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 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.
