Washing hints
Quantity of detergent to be
used
The type and quantity of detergent will
depend on the type of fabric, load size,
degree of soiling and hardness of the water
used.
Water hardness is classified in so-called
“degrees” of hardness. Information on
hardness of the water in your area can be
obtained from the relevant water supply
company, or from your local authority.
Follow the product manufacturers’
instructions on quantities to use.
Use less detergent if:
- you are washing a small load,
- the laundry is lightly soiled,
- large amounts of foam form during
washing.
