Cleaning
Daily
Clean the ceramic hob after use. You can use,
for example, a little washing-up liquid in
water. Switch on the child safety lock before
cleaning the control panel. Never clean the
ceramic hob with an abrasive cleaning
material!
Weekly
Special maintenance products for ceramic
hobs, such as Collo Profi or Cerafix give the
ceramic hob a protective layer. Treat the hob
with these products also when obstinate
stains have been removed.
Stubborn stains
You can remove burnt-on stains, metal and
lime scale stains from the ceramic hob with
such special cleaning materials as Jif, Collo
Luneta or Stahlfix.
Boiled-over food residues
Remove boiled-over food residues with a
glass scraper. Molten plastic and sugar can
also be removed with a glass scraper.
Do not first allow the hob to cool completely.
Special maintenance products for ceramic
hobs (e.g. Collo Luneta) form an antistatic
layer on the hob so that it attracts dust less
readily.
