Zanussi ZKT 650 D Instruction Book page 13

Remove burned-in sugar and melted plastic immedi-
ately – while it is still warm (not hot) – with a glass
scraper. Otherwise, damage can occur. Next, clean
the cooking field normally. Damage caused by sugar
or food containing sugar can be prevented by caring
for the cooking surface with Collo-Profi or Cerafix.
Spots
Limescale stains, mother-of-pearl-like shiny stains,
metallic iridiscent discolourations, pan abrasions
that have formed during cooking can be removed
best while the cooking zones are still warm. Use one
of the cleaners mentioned above. If necessary, clean
more than once.
Attention!
1
Do not put vinegar, citric acid (lemon juice)
or scale removers on the hob frame, they will
make the surface matt.
Sand grains which have fallen onto the cooking field
can cause scratches when pans are moved. There-
fore,ensure that no sand grains remain on the cook-
ing field.
Abraded décor
If aggressive cleaners or pans with abrasive bases
are used, then the decor will take on an abraded
appearance and dark spots will appear over time.
