Avoiding staining
Only proper cleaning of the instruments prior to sterilization enables you to avoid residue from being re-
leased from the load under steam pressure during sterilization. Loosened dirt residue can clog the filter,
nozzles and valves of the steam sterilizer and deposit themselves on the instruments and chamber as de-
posits and stains.
All steam-conducting parts of the steam sterilizer consist of non-rusting material. This rules out the possi-
bility of stain or rust development being caused by the steam sterilizer. Any rust which develops is always
extraneous rust.
Incorrect instrument decontamination can result in the accretion of rust even on stainless steel instruments
of leading manufacturers. Often, an instrument which drops rust can suffice to cause the development of
rust on another instrument or in the steam sterilizer. Remove extraneous rust from the instruments using a
chlorine-free stainless steel cleaning agent (see the
page 63] section) or send the damaged in-
struments to the manufacturer for treatment.
