How much washing powder and fabric softener?
The amount to be used depends on
• the load:
If the washing powder producer does not make any specifications for
small loads, use a third less for half loads, and for very small loads only
use half of the amount of washing powder recommended for a full
load.
• the degree of soiling of the washing:
For only slightly soiled washing use less washing powder. Follow the
instructions of the washing powder producer and load.
• on the degree of hardness of the tap water:
The harder the water, the higher the dosage! You will find the quanti-
ties to use according to water hardness on the washing powder pack-
aging.
Liquid detergent
Add liquid detergent using the dosing device provided by the detergent
industry. Please follow the instructions on the package.
Using a water softener
For a medium to high degree of water hardness (from water hardness
area II) water softener should be used. Follow the manufacturers
instructions! Then always dose detergent for hardness area I (= soft).
You can find information about the local degree of water hardness
from your water utility.

As the water softener has to be added before the main detergent (pre-
softening of the water), 80% of the water softener otherwise needed is
sufficient.
