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.
