What do I do with 'spills'?
Allow the hob to cool before cleaning.
Remove spills with a clean, damp cloth
(no detergent). If there is detergent in
the cloth, you may leave a layer of soil-
laden detergent on the hob surface which
can result in discolouration next time the
area is switched 'on'. This is why
dishcloths and washing-up sponges
should not be used. If it happens the
special Cleaner-Conditioner provided
will remove it.
In particular, sugar solutions e.g. jams
and syrups, must be wiped off the hob
surface before they set and become hard
to avoid the surface being damaged (see
'Important Notes' page 22).
