Reaction between process chemicals and soiling
Problem
Solution
Natural oils and fats can be emulsified with
alkaline process chemicals. This can lead to
a heavy build-up of foam.
- Use the
Oil
program.
- Use a special program that dispenses pH-
neutral emulsifiers containing surfactants
in the pre-rinse.
- Depending on the application, use de-
foaming agents that do not contain sili-
cone oils.
Soiling containing high protein levels can
cause a heavy build-up of foam when pro-
cessed 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.
