Miele KM 6310 Operating And Installation Instructions page 45

Do not use dishwashing liquid for cleaning. When cleaning
with a dishwashing liquid, not all contaminants and
residues are removed. The result is an invisible film, which
leads to discolouration of the ceramic surface. This
discolouration cannot be removed.
Clean the cooktop on a regular basis with a special
ceramic cleaner.
First wipe down the surface with a damp cloth to loosen
soiling, then remove stubborn crusting with a glass scraper.
Next, clean the cooktop with the Miele ceramic and stainless
steel cleaner (see "Optional accessories"), or a commercial
ceramic cleaner and paper towel or a clean cloth. Do not
apply cleaner to a hot cooking zone as this can leave spots.
Follow the instructions of the manufacturer of the cleaning
product.
Wipe the cooking zone with clean water and dry it with a
clean, dry cloth. Be sure to remove all cleaning product
residue. Residue will burn into the cooktop during
subsequent uses, damaging the glass ceramic.
Spots from lime deposits, water, and aluminium deposits
(shimmering metallic spots) can be removed with a glass
ceramic and stainless steel cleaner.
If sugar, plastic, or aluminium foil fall onto a hot cooking
zone, switch the appliance off. Immediately, while the zone is
still hot, use a glass scraper to thoroughly remove the spill
from the cooking zone. Risk of burns!
Once the zone has cooled off, clean thoroughly as described
above.
