cutlery after washing, decrease the amount of rinse aid.
4.3 Dishwasher detergent
Dishwasher detergents are divided into 2 groups due to their
chemical composition:
conventional, alkaline detergents with caustic components.
low-alkaline concentrated detergents with natural
enzymes.
"Normal" programmes combined with concentrated detergents
prevent pollution and are also good for your dishes. Such
programmes support the washing effect of the enzymes.
Therefore, "normal" programmes combined with concentrated
detergents are as effective as "intensive" programmes.
There are three kinds of dishwasher
detergents:
(1)
with phosphate and chlorine.
(2)
with phosphate / without chlorine
(3)
without phosphate / without chlorine
Most recent powdered dishwasher detergents usually do not
contain any phosphate so they do not soften the water. In such
a case add a water softener (= dishwasher salt) even if the
hardness of water is e.g. 6
0
dH. Otherwise white spots may
occur on your dishes and glasses.
Dishwasher detergents without chlorine only bleach slightly,
so they do not remove tough stains. In such a case select a
programme with a higher temperature.
