Pay attention to following points when selecting the
cleaning detergent:
– fundamental suitability for the cleaning of instruments
made of metallic or plastic material
– additional application – in case of non-application of
a thermal disinfection – of a suitable disinfectant with
approved efficiency (for example VAH/DGHM or FDA/EPA
approval/clearance/registration or CE marking) compati-
ble with the used cleaning detergent
– compatibility of the used detergents with the components
(see chapter "Material Resistance")
Pay attention to the instructions of the detergent manufac-
turers regarding concentration, temperature and soaking
time as well as post-rinsing.
Procedure:
1. Transfer the disassembled components in the WD
(pay attention that the components have no contact).
If applicable (see chapter "Specific Aspects"): Use a
basket for small parts.
2. Start the program.
3. Remove the components from the WD after end of the
program.
4. Check and pack the components immediately after the
removal (see chapters "Check", "Maintenance", and
"Packaging", if necessary after additional post-drying at
a clean place).
Validation was carried out on an equivalent product by an
independent accredited and recognized test laboratory by
application of the WD G 7836 CD, Miele & Cie, Gütersloh,
(thermal disinfection) and the cleaning detergent Neodisher
medizym (Dr Weigert GmbH & Co. KG, Hamburg) according
to the specified procedure.
Manual cleaning and disinfection
Pay attention to following points during selection of the
cleaning and disinfection detergents:
– fundamental suitability for the cleaning and disinfection
of instruments made of metallic or plastic material
– in case of application of an ultrasonic bath: suitability of
the cleaning detergent for ultrasonic cleaning (no foam
development)
– application of a disinfectant with approved efficiency (for
example VAH/DGHM or FDA/EPA approval/clearance/
registration or CE marking) compatible with the used
cleaning detergent
– compatibility of the used detergents with the components
(see chapter "Material Resistance")
Combined cleaning/disinfection detergents should not be
used.
Only in case of extremely low contamination (no visible
impurities) combined cleaning/disinfection could be used.
– Pay attention to the instructions of the detergent
manufacturers regarding concentration, temperature
and soaking time as well as post-rinsing. Please use only
freshly prepared solutions as well as only sterile or low
contaminated water (max. 10 germs/ml), low endotoxin
contaminated water (max. 0.25 endotoxin units/ml),
for example purified/highly purified water, and a soft,
clean, and fluff-free cloth and/or filtered air for drying,
respectively.
Procedure:
Cleaning
1. Soak the disassembled components for the given soaking
time in the cleaning solution so that the components are
sufficiently covered. Pay attention that there is no contact
between the components and no remaining air in the
cavities. Assist cleaning by careful brushing with a soft
brush and ultrasonic treatment (duration at least once the
required soaking time in addition to brushing). If applica-
ble (see chapter "Specific Aspects"): Rinse all cavities of
the components at least five times at the beginning and
at the end of the soaking time using a disposable syringe
(minimum volume 5 ml). Brush holes clean using a coni-
cal interdental brush.
2. Then, remove the components of the cleaning solution
and post-rinse them at least three times intensively
(at least 1 min) with water. If applicable (see chapter
"Specific Aspects"): Rinse all cavities of the components
at least five times at the beginning and at the end of
the soaking time using a disposable syringe (minimum
volume 5 ml).
3. Check the components (see chapters "Check" and
"Maintenance").
Disinfection
4. Soak the disassembled components for the given soaking
time in the disinfectant solution so that the components
are sufficiently covered. Pay attention that there is no
contact between the components and no remaining
air in the cavities. If applicable (see chapter "Specific
Aspects"): Rinse all cavities of the components at least
five times at the beginning and at the end of the soaking
time using a disposable syringe (minimum volume 5 ml).
5. Then, remove the components from the disinfectant solu-
tion and post-rinse them at least five times intensively
(at least 1 min) with water. If applicable (see chapter
"Specific Aspects"): Rinse all cavities of the components
at least five times at the beginning and at the end of
the soaking time using a disposable syringe (minimum
volume 5 ml).
