Reaction between chemical agents and soiling
Problem How to resolve it
Natural oils and fats can be emulsified
with alkaline chemical agents. This can
lead to a heavy build-up of foam.
Where available use the "OEL“
programme.
This special programme dispenses
emulsifiers (pH neutral) in the
pre-rinse.
Depending on application use
de-foaming agents that do not
contain silicone oils.
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 aluminium,
magnesium and zinc can release
hydrogen when processed with very
acidic or alkaline chemical agents
(oxyhydrogen reaction).
Please observe chemical agent
manufacturer's instructions.
