To keep the appliance in good condition, clean it
using suitable products and implements once it
has cooled down. This will make the job easier
and avoid the build-up of dirt. Never use harsh
cleaning products or tools that could scratch the
surface, or steam-operated equipment.
Light dirt not stuck to the surface can be cleaned
using a damp cloth and a gentle detergent or
warm soapy water. However, for deeper stains or
grease use a special cleaner for ceramic hot
plates and follow the instructions on the bottle. Dirt
that is firmly stuck due to being burned repeatedly
can be removed using a scraper with a blade.
Slight tinges of colour are caused by pots and pans
with dry grease residue underneath or due to
grease between the glass and the pot during
cooking. These can be removed using a nickel
scourer with water or a special cleaner for ceramic
hot plates. Plastic objects, sugar or food containing
a lot of sugar that have melted onto the surface
must be removed immediately using a scraper.
Metallic sheens are caused by dragging metal pots
and pans over the glass. These can be removed
by cleaning thoroughly using a special cleaner for
ceramic glass hot plates, although you may need
to repeat the cleaning process several times.
