Soiling
Problem
How to resolve it
The following substances can lead to a
heavy build-up of foam during washing
and rinsing:
– some disinfecting agents and
dishwashing detergents,
– active foaming agents such as
tensides.
– Thoroughly rinse items in water
beforehand.
– Select a cleaning programme with at
least one short pre-rinse in cold or
hot water.
The following substances cause
corrosion to stainless steel in the wash
cabinet and on accessories:
– hydrochloric acid,
– other substances containing
chlorides such as sodium chloride
etc.,
– concentrated sulphuric acid,
– chromic acid,
– particles of iron and swarf.
– Thoroughly rinse items in water
beforehand.
– Place items drip dried into mobile
units, baskets and inserts and then
place these in the wash cabinet.
Reaction between chemical agents and soiling
Problem
How to resolve it
Soiling containing high protein levels
such as blood can cause a heavy
build-up of foam when processed with
alkaline chemical agents.
– Select a cleaning programme with at
least one short pre-rinse in cold
water.
Non-precious metals such as
aluminium, magnesium and zinc can
release hydrogen when processed with
very acidic or alkaline chemical agents
(oxyhydrogen reaction).
– Please observe the chemical agent
manufacturer's instructions.
