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 "OIL"
programme.
– This special programme dispenses
cleaning agents containing tensides
(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 the chemical agent
manufacturer's instructions.
