6.2 Protecting the
plastic surfaces
Do not put liquid oils or oil-
cooked meals in your refrigerator
in unsealed containers as they
damage the plastic surfaces of
the refrigerator. If oil is spilled or
smeared onto the plastic surfaces,
clean and rinse the relevant part
of the surface at once with warm
water.
6.3 Door Glasses
Remove the protective foil on the
glasses.
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
silicones 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.
Water-based cleaning products that
are not alkaline and corrosive must be
used for regular cleaning purposes.
Non-alkaline and non-corrosive
materials must be used for cleaning
so that the service life of this coating
lasts for a long time.
These glasses are tempered to
increase their durability against
impacts and breaking.
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.
