Cleaning and care
Stainless steel refers to extremely corrosion-resistant, hygienic steels. The stainless steel that
B.PRO currently uses primarily consists of iron, chrome and nickel.
The corrosion resistance in stainless steel is provided by what is known as a passive layer, for-
med on the material surface when it comes into contact with oxygen. Damage to the passive
layer caused by mechanical impact is automatically repaired if sufficient oxygen is present on the
material's surface.
However, the stability of this passive layer can be breached by chemical reaction and by layers of
grease, starch, protein and lime scale, which help to cause corrosion.
The following substances may also cause or advance corrosion if they come into contact with
stainless steel:
•
Concentrated acids, halogens, such as chlorides or bromides, and their salts, and seasoning
containing cooking salts
•
Acid vapours which may form when industrial cleaners are used, for example
•
Contact with other metals, such as steel or iron
•
Contact with iron, such as iron contained in steel wool, chips from pipelines or water contai-
ning iron particles
)
Stainless steel surfaces must be kept clean, dry and open to the air at all times.
Contact with the aforementioned substances must be avoided to maintain corrosion resistance.
You must observe the following instructions on cleaning and care.
B.PRO recommends:
Treating heavily used stainless-steel surfaces, such as heated bain-marie wells, with
DeepClean Stainless Steel on a regular basis in addition to daily routine cleaning. This ensures
that the passive layer on the stainless-steel surface and, consequently, its corrosion resistance,
are preserved for a longer period of time.
The unit must be thoroughly cleaned and dried after each use.
Caution!
Fire hazard
Soiling in odour filter box can ignite in the worst case.
– Clean filter cassettes and odour filter box depending on how dirty they are, but at least once
a week.
Wiping clean with a damp cloth forms a mandatory part of the daily routine cleaning. Stubborn
stains may be removed with a brush (synthetic or natural bristles).
Any other cleaning methods must be approved by B.PRO.
)
Do not use steam jet units, high-pressure cleaners, water sprayers or similar cleaning devices.
)
Do not use integrated heating systems to dry surfaces under any circumstances.
