Cleaning and care

•
Take the appliance out of operation before starting the cleaning process.
Pull out the mains plug and insert it into the holder provided on the appli-
ance. Empty the bowls.
•
Do not clean the appliance with steam-jet or high-pressure cleaners. If it is
anticipated that steam-jet or high-pressure cleaners will be used in the sur-
roundings, then the appliance must be taken out of operation and discon-
nected from the mains power supply beforehand.
•
For cleaning, the appliance must be out of operation and sufficiently
cooled.
If after cleaning there are still limescale deposits present these must be re-
moved since otherwise the energy consumption increases and the appliance
becomes less economical. In the event of severe limescale deposits the appli-
ance may sustain damage. Use commercially available surface descalers or
vinegar water for descaling.
The drain cock can be re-greased with food grease (cooking fats are unsuita-
ble for this purpose) in order to provide sealing and ease of action.
Valuable information about "refined stainless steel"
The resistance to corrosion of stainless steels is based on a passive layer
which is formed on the surface when oxygen is admitted. The oxygen in the
air is sufficient for the formation of the passive layer, so that faults or damage
to the passive layer can be remedied again automatically by mechanical ac-
tion. The passive layer develops or reforms more quickly when the steel
comes into contact with flowing water containing oxygen. A further increase in
the effect is achieved by acids having an oxidising action (nitric acid, oxalic
acid). These acids are used if the steel has been severely chemically stressed
and therefore has largely lost its passive layer. The passive layer can be
chemically damaged or disrupted by agents having a reducing (oxygen-con-
suming) action when the steel comes into contact with them in concentrated
form or at high temperatures. Such aggressive substances are for example:
•
substances containing salt and sulphur
•
chlorides (salts)
•
seasoning concentrates such as mustard, vinegar essence, seasoning
cubes, saline solutions, etc.
Further damage can occur due to:
•
extraneous rust (e.g. from other components, tools or rust film)
•
iron particles (e.g. grinding dust)
•
contact with non-ferrous metals (element formation)
•
lack of oxygen (e.g. no admission of air, water with a low oxygen contend).
General working principles for the handling
of appliances made from "refined stainless steel"
Always keep the surface of appliances made from stainless steel clean and
accessible to the air.
Remove layers of limescale, grease, starch and egg-white daily by cleaning.
Corrosion can occur underneath these layers due to lack of air admission. No
bleaching and chloride-containing cleaning agents should be used.
If no special cleaning recommendations are given, low-chloride cleaning
agents should be used in any case.
After each cleaning operation remove all cleaning agent residues by rinsing
with copious fresh water. Afterwards the surface should be thoroughly dried.
