Cleaning catalytic enamel
surfaces
The roof and the back wall of the oven
and side panels (if fitted) which can be
difficult to reach for cleaning have
special liners which are coated with
catalytic enamel. Catalytic enamel has
very good self-cleaning properties.
During fan operated cooking circulating
air in the oven deposits oil and fat
splashes predominantly on the back
panel of the oven.
The catalytic liners absorb oil and
splashes of fat. These splashes are
burnt off at temperatures over 200°C.
The higher the temperature, the more
effective the process.
Before cleaning the catalytic panels
using high temperatures, make sure
that all P
ERFECT
C
LEAN
surfaces have
been cleaned as previously
described. Otherwise, the high
temperatures can cause deposits to
become baked on to the
P
ERFECT
C
LEAN
surfaces and become
impossible to clean.
Depending on the level of soiling,
heating the oven to a high temperature,
as follows, will help remove soiling on
the catalytic surfaces which has been
caused by oil and grease splashes:
^
With the oven empty, select Fan heat
D
and the highest temperature
possible. Run the oven for approx.
one hour.
The length of time will depend on the
level of soiling.
It is a good idea to set the finish time for
the process using the timer (see
"Switching off automatically"). This way
you will not forget to switch the oven off
at the end.
However, deposits of spices, syrups
and similar substances are not
removed by the catalytic cleaning.
These are best removed while fresh by
hand with a mild solution of warm water
and washing up liquid applied with a
soft brush. Do not wait too long
between cleaning sessions as further
baking and roasting will cause the
deposits to bake on even harder with
each subsequent use of the oven.
Do not use abrasive cleaning
agents, hard brushes, scouring
pads or cloths, steel wool, knives or
other abrasive materials and do not
use oven spray on catalytic enamel.
These damage the surface
rendering its self-cleaning properties
ineffective.
After a period of time and depending
on the amount and type of use of the
oven, the matt surface of the catalytic
liners can change in appearance, e.g.
splashes of fat will be visible, and
become ineffective. The liners should
then be replaced with new ones.
Replacement liners can be obtained
from your dealer or the Miele Spare
Parts Dept and fitted as described in
the following section.
