Soiling
Problem How to resolve it
The following substances can lead to heavy
build-up of foam during washing and
rinsing:
- some disinfection agents, cleaning
detergents, etc.
- active foaming agents such as surfactants
- Thoroughly rinse items in water
beforehand.
- Select a cleaning program with at least
one short pre-rinse in cold or hot water.
The following substances can cause
corrosion to stainless steel in the wash
cabinet and the accessories:
- hydrochloric acid
- other substances containing chlorides,
such as sodium chloride
- concentrated sulfuric acid
- chromic acid
- particles of iron and shavings
- Thoroughly rinse items in water
beforehand.
- Put the drip-dry items to be washed into
the mobile units, baskets, modules, and
inserts and start a reprocessing program
as soon as possible after placing in the
wash cabinet.
Reaction between process chemicals 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 process
chemicals.
- Select a cleaning program with at least
one short pre-rinse in cold water.
Non-precious metals such as aluminum,
magnesium, and zinc can release hydrogen
when processed with very acidic or alkaline
process chemicals (oxyhydrogen reaction).
- Please observe the process chemical
manufacturer’s instructions.
