Grease stains and metallic traces can be eliminated with "ZIP" stainless steel liquid or pow-
der.
Detergent residue should always be thoroughly removed with a damp cloth, as they can have
a corrosive effect when the plate is next used. Always wipe until dry.
Never use abrasive or corrosive detergents, oven sprays, scouring powders, abrasive sponges
or steel wool.
Scratches can be caused through the use of pots and pans with uneven or rough bottoms.
These scratches cannot be removed, but in no way do they affect the efficiency of your coo-
king surface.
Spills and splashes should be wiped as soon as possible. Check that they have been removed
before using the hob again.
To remove tough stains and metal marks, use a drop of a gentle cleaning product, preferably
a cream one.
To remove water and scale marks, use a few drops of white alcohol vinegar.
To finish off, always rinse with clean water and then wipe with absorbent paper.
Be careful not to allow liquid to run into ventilation inlets under the hob.
You are advised not to use abrasive products or scouring powder (steel wool, abrasive sponges).
These may leave scratch marks on the visible parts of your hob.
The rubbing of pans may, in the long term, lead to a deterioration of the patterns on the glass
ceramic surface.
These defects in appearance do not lead to a non-functioning of the hob or the impossibility of
using it and are not covered by the guarantee.
- Do not immerse your appliance.
- Do not clean it under the tap.
