External disinfection
This procedure reduces the risk of infection during cleaning and maintenance of the instrument.
Wear protective gloves during disinfection.
Refer to the instructions of the instrument manufacturer.
Avoid using abrasive disinfectants (pH-value 2.5 – 9; no chlorine based disinfectants).
We recommend the use of disinfectant wipes rather than spray disinfection.
Do not immerse instruments in disinfectants.
Residual disinfectants on instruments can cause extensive damage to your instrumentation during sterilization (oxidation, alteration
of technical characteristics of seals, rubbers, fiber optics, etc.).
External cleaning
This procedure involves the removal of residues (blood, dentine, etc.) that adhere to critical areas such as spray outlets, light ports,
knurling etc.
Wear protective gloves during cleaning.
Refer to the instructions of the instrument manufacturer.
Use a soft, damp brush and take care not to scratch the surface of the light ports.
Lubrication
Once the instrument has been disinfected, cleaned and dried (free from residues), it must be lubricated prior to sterilization.
Follow manufacturer’s instructions for proper lubrication.
Packaging
In order to preserve sterility, rotating instruments should be wrapped/bagged prior to sterilization. Follow the manufacturer’s packing
instructions when using sterilization packaging (also see “Sterilization load preparation” in ANNEX 3 of this manual).
