Door Glasses
C
Remove the protective foil on the
glasses.
C
There is a coating on the surface of
the glasses. This coating minimizes
the stain build-up and helps to
remove the possible stains and dirt
easily. Glasses that are not protected
with such a coating may be subject
to persistent binding of air or water
based organic or inorganic dirt
such as limescale, mineral salts,
unburned hydrocarbons, metal
oxides and sliciones that can easily
and quickly cause stains or material
damage. Keeping the glass clean
becomes too difficult despite the
regular cleaning. Consequently, the
appearance and the transparency
of the glass deteriorates. Harsh
and corrosive cleaning methods
and compounds will intensify
these defects and speed up the
deterioration process.
C
Water-based cleaning products
that are not alkaline and corrosive
must be used for regular cleaning
purposes.
C
Non-alkaline and non-corrosive
materials must be used for cleaning
so that the service life of this coating
lasts for a long time.
C
These glasses are tempered to
increase their durability against
impacts and breaking.
C
A safety film is also applied to their
rear surfaces as an extra safety
measure in order to prevent them
from causing damage to their
surrounding in case of a breakage.
*Alkali is a base that forms hydroxide ions
(OH¯) when it is dissolved in water.
Li (Lithium), Na (Sodium), K (Potassium)
Rb (Rubidium), Cs (Cesium) and
artificial and radioactive Fr (Fan-sium)
metals are called ALKALI METALS.
