If sugar or a preparation containing sugar comes into contact
with a hot cooking zone and melts, it should be cleaned off
immediately with a kitchen scraper while it is still hot. If allowed
to cool, it may damage the surface when removed.
Keep all items and materials that could melt, for example,
plastics, aluminium foil and oven foils, away from the ceramic
glass surface. If something of this nature melts onto the hob, it
must be removed immediately with a scraper.
