When such discolourations are observed, the
plate should be immediately cleaned with the
cleaners mentioned above.
Thicker layers of scale can only be removed by
intensive cleaning, which may have to be
repeated several times to be effective.
• Household items made of plastic (spoons,
bowls, dishes, etc.) must on no account be
placed on the hot cooking surface. The plastic
will melt and stick to the hot surface.
Should this occur, the surface is to be scraped
clean at once while the plate is still hot.
• Do not use sponges or cloths which have
already been used for other purposes.
Used sponges or cloths may leave behind a
layer of liquid or coloured water which will give
the glass ceramic a brown colour. This
discolouration will only become visible when the
cooking plate becomes hot. If such a
discolouration occurs, the cooking plate should
be cleaned again as described before.
