MAINTENANCE FOR DOORBIRD PRODUCTS
Cleaning and maintenance instructions
All DoorBird door stations 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.
Never use abrasive detergents such as steel
N OTICE
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 German 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
