Possible Solution

traces of oxidation or
spotting
Low quality instruments
Instruments made of inferior materials can be prone to discoloration.
Check the quality of the instruments that are spotting. Verify that they
can tolerate steam sterilization as per the instrument manufacturer’s
instructions for use.
Organic or inorganic residues
on the instruments
Instruments must be free of debris prior to sterilization. Clean and rinse all
instruments before loading them into the autoclave. Disinfectant residues
and solid debris may inhibit sterilization and damage the instruments and
the STATCLAVE G4. Lubricated instruments must be wiped thoroughly
and any excess lubricant should be removed before loading.
