Reactions between processing chemicals and soils
Effects Action
Natural oils and greases can be
saponified with alkaline processing
chemicals. This may cause a lot of
foaming.
–
Use the program OIL (if available).
–
Use the special program with dosing
of tenside cleaners (neutral pH) for
pre-rinsing.
–
Taking the specific application into
account, add an antifoaming agent,
one without silicone oils if possible.
In combination with alkaline processing
chemicals, loads with soiling that
contains proteins, e.g. blood, can
cause excessive foaming.
–
Select a wash program with one or
more short pre-rinses with cold
water.
In combination with very acidic or
alkaline processing chemicals, base
metals such as aluminum, magnesium
and zinc can release hydrogen
(detonating gas).
– Observe the instructions of the
manufacturer of the processing
chemicals.
