Discolouration of the hob does not have any influence on the
operation or strength of the vitroceramic. It is not a form of
damage to the hob, but it is a result of residues that have not
been removed and have therefore burntin.
Shiny spots occur as a result of wear caused by the base of the
pans, in particular when using cooking pans with an aluminium
bottom or when using the wrong cleaning agents. These can
only be removed with great difficulty using common cleaning
agents. If necessary, repeat the cleaning several times.
Due to the use of aggressive cleaning agents and scratching
caused by the pan bases, the glass surface is rubbed off over
the course of time, leaving dark stains.
Do not use the cooking plate as a table top or for putting
utensils on.
Always lift up the pans/pots and do not slide them along the
glass plate.
