Tips for washing special materials
Dishwasher-
suitable materials
Always check the dishes
manufacturer's
instructions before
washing in a dishwasher.
Aluminium
High wash temperatures and
concentrated detergent can
damage the finish of some
types of aluminium.
China/Earthenware
Antique decorations, hand-
painted details and gold rims
can fade or disappear.
Crystal
Some types of lead crystal
can become dull with
repeated washing in a
dishwasher. You can minimise
this effect by selecting low
temperature wash cycles.
Glass
Opaline glass yellows with
repeated washing.
Plastic materials
Different plastics react
differently to high
temperatures and
detergents. We recommend
you place plastic items in the
upper rack.
Materials not
suitable for your
dishwasher
Cast iron
The iron rusts and the
coating detaches.
Knives with hollow
handles
Some knives have glued-on
handles, which can detach
during washing in a
dishwasher.
Tin, copper, silver
High temperatures and
detergents can result in
tarnishing and damaging to
the surface of tin, copper and
silver.
Disposable plastic cutlery
Does not withstand high
temperatures and detergents.
Tin plate
May rust.
Wooden utensils
We recommend you wash
these by hand. Read the
utensil manufacturer's
instructions before washing
in the dishwasher. Untreated
wood may buckle, break or
deteriorate.
Bottles and cans
Must be washed by hand.
