Washing Detergents and Care Agents
Which detergent and care agent?
Use only detergents and care agents which are suitable for use in wash-
ing machines. Always follow the manufacturer's instructions.
How much detergent and care agent?
The amount to be used depends on:
•the dirtiness of the washing
•the hardness category of the mains water supply
•the quantity of washing
2 If the detergent manufacturer does not include dosing instructions for
reduced loads, use one third less for half loads and only half of the full
load detergent quantity for very small loads.
Refer to the detergent/care agent manufacturer's instructions on use
and dosage.
Water Softener
For medium to high water hardness (hardness category II or higher) you
should use water softener. Pay attention to the manufacturer's instruc-
tions. Always then meter detergent for hardness category I (=soft). The
responsible water works can provide information on the local water
hardness.
