Cleaning the appliance

! Do not use abrasive or corrosive detergents such as stain removers, anti-rust products, powder detergents or sponges with abrasive surfaces: these may scratch the surface beyond repair.
! Never use steam cleaners or pressure cleaners on the appliance.
- It is usually enough to wash the hob with a damp sponge and dry it with absorbent kitchen roll.
- The removable parts of the burners should be washed frequently with warm water and soap and any burnt-on substances removed.
- For hobs which lighth automatically, the terminal part of the electronic instant lighting devices should be cleaned frequently and the gas outlet holes should be checked for blockages.
- 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 solution 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. CERALWOW (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 a transparent protective layer which
