Cleaning and care
After the pyrolytic process any debris
(e.g, ash), can easily be wiped away.
Remember to wait until the oven has
cooled down before doing so!
Danger of burning!
Try not to wipe over the fibre-glass
seal when cleaning the oven cavity.
It is particularly sensitive and should
not be cleaned unless absolutely
necessary. Rubbing it can damage
it.
Most residues are easily wiped away
with a damp cloth.
Depending on soiling levels in the oven
there may be visible deposits on the
door and below the trim under the oven
cavity. This is best removed using a
non-abrasive sponge or non-abrasive
spiral pad and a mild solution of warm
water and washing-up liquid.
Deposits on the internal door panel can
be removed using a suitable glass
scraper.
Spilt fruit juices may cause lasting
discolouration to the surfaces. This
discolouration is permanent but will
not affect the efficiency of the
enamel. Do not attempt to remove
these marks.
