Stoves with glass ceramic cooking surfaces
WHAT IS CERAN® ?
Glass ceramic cooking surfaces by the Mainz-based company SCHOTT (Germa-
ny) are extremely temperature-resistant and withstand even abrupt temperature
shocks up to 750°C.
CERAN® is insensitive to normal mechanical loads in the kitchen. The 4 mm
thick glass ceramic also transmits heat very well. It allows radiated heat to pass
with almost no loss, but hardly conducts any heat to the sides.
CERAN® cooktop panels are easy to clean and allow you to enjoy the beauty
of real fl ames.
CARE AND PRACTICAL TIPS FOR GLASS CERAMIC COOKING PLATES
Clean your glass ceramic cooktop panel thoroughly before initial use, then
regularly while it is warm (not hot) or cold. Avoid repeated burning-in of con-
taminants.
For cleaning we recommend:
• Kitchen paper towels or a clean cloth
• Razor blade scraper (Caution: only for the top. On no account must it be used
to remove combustion residue from the (rough) underside of the plate as
this would scrape off irregularities – which in turn would result in scratches
(“predestined fracture points”).
• Commercially available glass ceramic cleaners.
The degree of contamination determines the choice of cleaning agents:
• Use a moist cloth to wipe off contamination that is not burnt-on.
• All coarse and fi rmly adhering contamination is easily removed with the razor
blade scraper; spots of scale, watermarks, grease splashes and metallic-
looking discolorations are best cleaned with commercially available glass
ceramic cleaning agents.
All traces of cleaning agents must be thoroughly wiped off moist after cleaning
(even if their instructions are different), since they could have a corrosive effect
when reheated. As a fi nal step, wipe it dry. When correctly used, the glass ce-
ramic cooking surface will retain its attractive appearance.
WHAT IF...?
... a chemical cleaning agent alone is not suffi cient?
Check to see whether the razor blade scraper gets you there much more quickly.
... metallic looking discolorations appear on the cooking zones over time?
Unsuitable cleaning agents were mainly used. At this stage, the discolorations
can only be removed with diffi culty using Sidol®, alcohol or scouring pads.
... the surface has scratches or minor chippings?
These blemishes caused by scratching or baked-on substances cannot be re-
paired. However it does not impair the serviceability of your stove in any way.
... wenn dunkle Flecken entstanden sind?
If cleaning with the razor blade scraper, Sidol®, alcohol or scouring pads does
not yield any improvement, it is probably abrasion of the decoration caused by
unsuitable cleaning agents or the scouring action of the bases of pots.
WHERE CAN THE CLEANING AGENTS BE BOUGHT?
Cleaning agents for glass ceramic surfaces are available e.g. in department
stores (electrical appliance section), electrical appliance shops, chemist’s shops,
supermarkets and in shops specialising in kitchens.
