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.
