An unsatisfactory wash result

Problem
Liquid detergent does not

like powder detergent are
seen on dark textiles after
washing.
Textiles with particularly
greasy soiling are not
properly clean.
Grey, greasy particles
cling to washed laundry.
38
Cause and remedy
Liquid detergents usually contain no bleaching agents.
They do not remove fruit, coffee, and tea stains.
Use a general purpose powder detergent containing a

bleaching agent.
Pour stain removers into the  drawer in the dispenser

compartment and liquid detergent into a dispenser ball.
Never put stain removers and liquid detergent together in

the dispenser drawer.
The detergent contained compounds (zeolites) to aid water
softening which are not soluble in water. These have ended
up on the laundry.
Try to brush off the residues with a soft brush once the

laundry is dry.
In future, wash dark textiles using a detergent which

contains no zeolites. Liquid detergents usually contain
no zeolites.
Select a programme with pre-wash. Use liquid detergent

for the pre-wash.
Continue to use universal powder detergent for the main

wash.
The use of heavy-duty detergent is recommended in the
main wash for very heavily soiled work clothing. Please seek
advice from the detergent manufacturer.
Insufficient amounts of detergent were used. to break
down the particles of grease in heavily soiled laundry.
Use more detergent.

Before washing the next load run a 60 °C programme

with powder detergent but without a load.
