9.6 Cleaning
NOTICE
Damage caused by aggressive cleaning agents
Aggressive chemical agents can damage the electronics. This can result in malfunction.
Never use any type of chemical agent or liquid.
● Only remove severe dirt and contamination after prior consultation with service experts for
the particular product.
Use a dry, clean, lint-free ESD cleaning cloth. Wipe all external parts of the rack with it. Make
sure that the dirt is not distributed, but actually removed by constant changes of the wiping
surface of the cloth. For significant levels of pollution and dirt, use an ESD cloth soaked in ethyl
alcohol (however, not so much that it drips from the cloth).
9.6.1 Cleaning aluminum parts
The surface of untreated aluminum is always covered by a thin but dense oxide skin. This
natural oxide layer acts as surface protection and is the reason for the good weathering
resistance of aluminum materials. In most cases, this means that additional protective
measures are superfluous.
● Remove greasy layers using ethyl alcohol.
● If there are other very dirty areas, use ESD-compliant fiber or plastic brushes for cleaning.
NOTICE
Corrosion damage caused by unsuitable cleaning agents and cleaning instruments
Using unsuitable cleaning chemical agents and cleaning instruments may transfer
metallic, corrosion-inducing impurities onto the aluminum. This can result in corrosion
damage.
● Only use cleaning agents that are suitable for aluminum.
● Use ESD-compliant brushes and cloths.
● Do not use cleaning cloths and brushes that have already been used to clean copper,
brass, bronze or other heavy metals.
● Use neither brass, bronze, or steel-wire brushes nor cloths or steel wool interwoven
with copper wire.
