Catalytic enamel surfaces
The back panel and the roof liner and
side liners (if fitted) are coated with
dark grey
catalytic enamel . Soiling
from oil and fat is burnt off these
surfaces when very high temperatures
are used in the oven. The higher the
temperature, the more effective the
process.
The catalytic coating becomes
ineffective through using
–
abrasive cleaning agents,
– hard brushes or abrasive
sponges,
– oven sprays.
Remove the catalytic back panel
and any side and roof panels from
the oven before cleaning the
PerfectClean oven surfaces with
oven spray.
Note that deposits of spices, syrups
and similar substances are not
removed from the catalytic coating by
this process. These should be removed
by hand whilst still fresh, using a mild
solution of hot water and washing up
liquid applied with a soft sponge or
brush. Remove the panels from the
oven to do this.
Soiling caused by oil and grease
splashes are removed from catalytic
coated surfaces when the oven is
heated to a high temperature. To do
this:
^ Take all accessories out of the oven.
^ Wipe large deposits of soiling from
the oven interior and the inside of the
door before starting the cleaning
process to avoid them baking onto
PerfectClean surfaces and becoming
impossible to remove.
^ Select Fan plus Y.
^ Set the highest temperature setting.
Run the oven for approx. 1 hour. The
length of time will depend on the level
of soiling.
On models with a clock/timer, you can
set this procedure to finish
automatically; see the appropriate
section.
Any remaining soiling will gradually
disappear with each subsequent use of
the oven at high temperatures.
If the catalytic coated panels are
very heavily soiled with oil and
grease, a film will develop on the
oven surface during the cleaning
process which can be wiped off with
warm water and a little washing up
liquid once cool.
^ Finally, clean the PerfectClean
surfaces and the inside of the door.
Should the catalytic coating on the
back panel or the roof liner become
ineffective through improper use or
heavy soiling, a replacement can be
obtained from your Miele dealer or
the Miele Spare Parts dept.
