Cleaning and care
Stainless steel
Resistance to corrosion
The corrosion resistance of stainless steel is based on the presence of a so-
called passive layer on the material surface.
Damage to the passive layer caused by mechanical influences is
automatically repaired when a sufficient amount of oxygen is present at the
material surface.
Injuries to the passive layer caused by (oxygen-consuming) chemical
substances will damage the material. Treatment with oxidising acids can
counteract this damage.
To maintain the corrosion resistance, observe the following information on
cleaning and care.
Cleaning frequency
The unit must be thoroughly cleaned after each use.
Cleaning methods
The prescribed cleaning method for routine daily cleaning is to wipe down the
unit with a damp cloth.
Persistent soiling may be removed with a brush (synthetic or natural bristles).
Do not use steam jet units, high-pressure cleaners, water sprayers or
similar cleaning devices.
Do not use pointed or sharp objects for cleaning.
Cleaning agents
Stainless-steel surfaces
Caution!
Material damage!
Contact of stainless steel with the following substances can cause corrosion:
– Concentrated acids, halogens (chlorides, bromides, iodides) and their
salts or spices
– Acid vapours which, for example, develop when laying tiles
– Contact with other metal
– Contact with iron (e.g. steel wool, chips from lines, water containing iron.
Corrosion can also result under lime, grease, starch and protein layers due to
a lack of air circulation.
Avoid contact with concentrated acids, halogens and their salts, spices,
other metal, iron or substances containing iron. Wipe with a cloth rinsed
in clean water if necessary.
Do not damage the surface of stainless steel, especially not with other
metals.
Regularly remove lime, fat, starch and protein coatings by cleaning.
The following cleaning agents may be used:
Commercial cleaning agents in aqueous solution
Soft cleaning cloth
B.PRO microfibre cleaning cloth (use with water only)
