MAINTENANCE OF THE FRONT PANEL
Cleaning and maintenance instructions
All of our front panels are made of high-quality
materials and are designed for a durable lifetime.
Since door stations are usually installed in unprotected
outdoor areas, they are exposed to adverse weather
conditions and aggressive substances, especially close
to frequently used roads, in coastal and industrial
areas. Therefore, please consider the following care
instructions. Unfortunately, we cannot accept any
liability for damage if these instructions are not being
observed. Aggressive dirt such as bird droppings
should be removed as quickly as possible.
Aggressive stains such as bird droppings
NOT IC E
should be removed as soon as possible.
Never use abrasive detergents such as steel
NOT IC E
wool or scouring milk!
Warm water is usually sufficient, if necessary with
a little detergent, a soft cloth or brush. Plastic parts
(camera or name tags) must not be treated with metal
care products. Remove all residues of cleaning agents
or lubricants to avoid stains or discolouration after the
maintenance.
Stainless Steel
Only high-quality stainless steel is used for all available
DoorBird door stations. However, high-quality stainless
steel can also rust, as approx. 70 % of stainless steel
is made of iron. Rust resistance is only achieved by
a protective layer (also called passive layer), which
covers the iron like a skin. This protective layer consists
essentially of chromium and other precious metals.
Iron particles, grinding dust and chips deposited on
stainless steel can lead to corrosion (rust film). These
iron particles can be found everywhere, but especially
in coastal and industrial areas and close to frequently
used roads. Please remove ferrous deposits immediately,
as they will attack your door station and lead to real
rust if not removed. To remove rust, simply wipe off the
dust; in addition, a care product is recommended, e.g.
WD 40, available e.g. at Amazon for less than € 5.00.
Simply apply in a thin layer and rub in. The same applies
if rust appears on the engravings on the stainless steel
surface.
Cement or lime splashes should be carefully removed
as soon as possible with a wooden spatula before
hardening.
The following cleaning detergents are not to be used
as they reduce corrosion resistance:
• products containing chloride and hydrochloric
acid
• Bleach (in case of accidental use, rinse thoroughly
with water)
• Silver polish
After the cleaning with clear water wipe with damp
cloth and rub dry to avoid lime traces. Lime residues
can be avoided by using demineralised water.
Stainless steel PVD coated
PVD coated, chrome-plated or gold-plated surfaces are
recommended to be cleaned with a grease-
dissolving detergent and clear water or with a clean
and dust-free microfibre cloth. For high-gloss surfaces,
use a scratch-free cloth (e.g. cleaning cloth for glasses,
furniture polishing cloth, etc.).
Lacquered surfaces
Clean painted surfaces and lettering with a soft,
scratch-free cloth moistened with a mild soap solution
(e.g. cleaning cloth for glasses, furniture polishing cloth,
etc.). To prevent stains or discolouration, the detergents
should be wiped off without leaving any residue.
Be particularly careful with lettering in order not to
damage the film or the print.
