EcoClean Direct
EcoClean Direct is the name of a new process for cleaning the cooking
compartment at Bosch, Siemens and Neff.
For this cleaning process, the enamelled interior walls and the ceiling of the
cooking compartment are covered with an additional ceramic coating.
The ceramic coating is especially coarse and fined pored. The enlarged surface
causes spraying fat and vapours to be distributed over a large area on and in the
special ceramic (blotter effect).

The ceramic coating consists of ceramic microspheres in which oxygen is
deposited. In connection with heat, the oxygen allows grease to oxidise and be
broken down into water (steam) and carbon dioxide (CO
2
).
The higher the temperature, the faster and better the cleaning effect.
Cleaning occurs during baking and roasting when temperatures greater than
200 °C are reached. This causes the ceramic coating to be regenerated and to
remain active for the entire lifecycle of the appliance.
Normally, no additional cleaning cycle is necessary. Should an additional cleaning
cycle be required as an exception due to special operating conditions, this will be
indicated in the display. A cleaning programme can be started manually.
Damage to the ceramic coating due to incorrect cleaning!
► Do not use oven spray, abrasive cleaning agents, tough brushes, scouring
sponges or steel wool soap pads to clean the ceramic coating.
► Use only a soft, damp sponge soaked in a little detergent to clean the
ceramic surface.
3.2.1
How it works
When food is heated, this produces spraying fat that comes into contact with the
ceramic coating of the cooking compartment.
This spraying fat is absorbed by the fine-pored ceramic coating, which causes it to
be surrounded by oxygen on all sides.
In connection with heat, the oxygen causes the spraying fat to oxidise. Water
(steam) and carbon dioxide are generated as a result of the oxidation.
This causes the ceramic micospheres to lose oxygen.
The next time they are heated, the ceramic microspheres are regenerated and are
filled with oxygen again. The cycle can start from the beginning.
