DETERGENTS AND ADDITIVES
The choice of detergent depends on:
• type of fabric (cottons, easy care/synthetics,
delicate items, wool).
Note: Use only specific detergents for washing
wool
• colour
• the wash temperature
• degree and type of soiling
Remarks:
Whitish residues on dark fabrics are caused by
insoluble compounds used in modern phosphate-
free powder detergents. If this occurs, shake or
brush out the fabric or use liquid detergents.
Use only detergents and additives specifically
produced for domestic washing machines.
When using descaling agents, dyes or bleaches for
the pre-wash, make sure that they are suitable for
use in domestic washing machines. Descaler could
contain components which can attack parts of your
washing machine.
Do not use any solvents (e.g. turpentine, benzine).
Do not wash fabrics in the machine which have
been treated with solvents or flammable liquids.
Dosage
Follow the dosage recommendations on the
detergent pack. They depend on:
• degree and type of soiling
• size of wash
full load follow the detergent manufacturer’s
instructions;
half load: 3/4 the amount used for a full load;
Minimum load (about 1 kg):
1/2 the amount used for a full load
• water hardness in your area (request information
from the water company). Soft water requires
less detergent than hard water (refer to water
hardness table)
Notes:
Too much detergent can result in excess foam
formation.
The cleaning effect deteriorates.
If the washing machine detects too much foam, it
may prevent spinning.
Insufficient detergent may result in grey laundry in
time and also calcifies the heating system, drum and
hoses.
