Detergents and additives
Good washing results also depend on the choice of detergent
and use of the correct quantities to avoid waste and protect
the environment. Although biodegradable, detergents contain
substances which in large quantities can damage the delicate
ecological balance of nature.
Always use good quality detergents suitable for use in
washing machines.
Follow the indications given by the detergent manufacturer
according to the weight of laundry, the degree of soil and
the hardness of the water in your area; if you do not know
how hard it is, ask your local Water Authority.
Powder detergents.
The washing powder should be placed in the appropriate
compartments of the dispenser drawer before starting the
programme. Special detergents are availaible for coloured
and delicate fabrics and for wool.
<<Concentrated>> powder detergents
Pour the concentrated powder detergent into the main
wash ( ) compartment.
Avoid selecting programmes including prewash when
concentrated detergents are used.
Liquid detergents
Using the new automatic dispenser for liquid detergents, it
is possible to use a liquid detergent for main wash phases.
Liquid detergents can be used instead of powder detergents
particularly for lightly soiled laundry and for medium or low
temperature washing programmes, while it is better to use
a powder detergent for high temperature washing program-
mes.
Liquid additives
Any liquid additives for softening the laundry must be
poured into the compartment
of the detergent dispenser
drawer before starting the programme.
The addition of water softener is particularly useful when
drying the clothes in a tumble dryer after washing to avoid
a static charge.
