Cleaning and sterilisation
The base unit and transmission fibre are wiped with an appropriate cleaning/disinfectant agent. (DGHM- or VAH-
listed/e.g. Dürr FD 322 or Mikrozid liquid)
Note: Unplug the mains adapter before cleaning the device!
Preparing the instruments generally involves cleaning followed by sterilisation.Place instruments (application
fibres/glass rod) in a burr steriliser or instrument bath filled with a suitable cleaning/disinfectant agent (mild
alkaline/aldehyde-free/alcohol-free/DGHM- or VAH-listed) immediately after use on patient. This prevents residues
from drying (protein fixation). Instruments (application fibres/glass rod) should be transported to the preparation site
in the burr steriliser, instrument bath or an appropriate container in accordance with accident prevention regulations
(industrial safety/employer's liability insurance association).
8.1
Cleaning
Instruments in the "critical B" category (handpieces) should generally be cleaned by machine according to RKI
guidelines. Manual pre-cleaning may be necessary for effective cleaning if the instruments are particularly dirty.
Instruments in the “critical A“ category (application fibres, glass rods) can alternatively be cleaned, according to RKI
guideline 2.1 in a dipping treatment (please note: not in combination with ultrasound). A subsequent steam
sterilisation is essential, according to section 8.2 of this GBA, RKI guideline section 5.
Instruments containing glass fibers must not be cleaned using ultrasonic baths due to the potential for damage.
•
Thoroughly clean and dry re-usable instruments immediately after use to minimise corrosion and possible
cross-contamination.
•
Validation of the cleaning, sterilisation and re-sterilisation processes and the correct setup of the
corresponding devices must be checked regularly.
•
Do not allow instruments to come into contact with any substances that contain chlorine or fluorine.
•
Do not allow instruments that are made entirely or partly of plastic to come into contact with strong acids or
bases, organic or ammonia-containing solvents, aromatic and/or halogen-containing hydrocarbons or
oxidising chemicals.
•
Do not allow aluminium or materials that contain aluminium to come into contact with any substances that
contain mercury. Even the slightest trace of mercury can cause considerable corrosion. Instruments made
from materials that contain aluminium may be wiped and cleaned only with (or placed only in) solvents or
disinfectant agents with a pH value between 4.5 and 8.5. Higher or lower pH values cause the neutral coating
of the aluminium-containing materials to detach, leading to corrosion.
•
Do not let dirt dry on the instruments, as this may make later cleaning difficult.
•
If corrosive substances, such as silver nitrate, iodine preparations, albothyl and mercury compounds are used
during the operation, all residues of these substances must be removed from the instruments immediately.
•
Instruments must not be placed in physiological saline solutions, as extended contact with these substances
can result in corrosion and changes to the instrument surfaces.
•
Do not use metal brushes or abrasive cleaners to clean the instruments. Subsequent rinsing with
demineralised water is recommended to prevent water spots. The instruments must then be dried
immediately. Sterile compressed air can be used for drying.
•
Rinsing in demineralised water is recommended after cleaning.
•
After cleaning, grease moving metal parts with a water-soluble lubricant approved for use with medical
products. Reassemble and, if applicable, tighten screws.
•
Submerge instruments entirely in the enzyme or alkaline solution (pH ≤ 12) and leave them to soak for ten
minutes. Gently brush the product using a brush with soft nylon bristles until all visible dirt marks have been
removed. Pay particular attention to the gaps, lumina, fitting surfaces, connections and other areas that are
difficult to clean. Lumina should be cleaned with a long, thin brush with soft bristles (i.e. a pipe-cleaner).
•
Note: Using a syringe or water jet can make it easier to rinse out areas that are difficult to access, as well as
small fitting surfaces.
