5.3 General notes

Encrusted or fixated residues from surgery can make the cleaning process
more difficult or ineffective, and can cause corrosion of stainless steels. To
avoid this, the time interval between application and processing should
not exceed 6 h, and neither fixating pre-cleaning temperatures >45 °C nor
any fixating disinfecting agents (active ingredients: aldehyde, alcohol) be
used.
Excessive doses of neutralizers or basic detergents can cause chemical
degradation and/or fading and obliteration of laser inscriptions on
stainless steel surfaces, regarding visual reading and machine-readability
of the inscriptions.
Residues containing chlorine or chlorides e.g. in surgical residues,
medicines, saline solutions and in the service water used for cleaning,
disinfection and sterilization will cause corrosion damage (pitting, stress
corrosion) and result in the destruction of stainless steel products. To
remove such residues, the products must be rinsed sufficiently with fully
desalinated water and dried thoroughly.
Only process chemicals that have been tested and approved (e.g. VAH/
DGHM or FDA approval or CE mark) and which are compatible with the
product's materials according to the chemical manufacturers'
recommendations may be used for processing the product. All process
parameters specified by the chemical's manufacturer, such as
temperatures, concentrations and exposure times, must be strictly
observed. Failure to do so can result in the following problems:
• optical changes to the material, e.g. fading or discoloration of titanium
or aluminum. For aluminum, pH >8 in the application/process solution
is sufficient to cause visible surface changes.
• material damage such as corrosion, cracks, fracturing, premature aging
or swelling.
Do not use process chemicals that cause stress cracking or brittleness
of plastic materials.
Further detailed advice on hygienically safe and material-/value-
preserving reprocessing can be found at www.a-k-i.org, link to
Publications, Red Brochure – Proper maintenance of instruments.

5.4 Preparations at the place of use

Remove visible surgical residues as completely as possible, using a lint-
free wet wipe.

5.5 Preparation prior to cleaning

Prepare the handpiece and the attachments in dry condition in a
disposal container/Eccos® storage for disinfecting cleaning within
30 min.

5.6 Cleaning/Disinfecting

Fire hazard!
Do not use flammable or explosive cleaning or
disinfecting solutions.
DANGER
Make certain that no fluids will penetrate the
product.
Damage to the product due to inappropriate
cleaning/disinfecting agents!
Only use cleaning/disinfecting agents approved
CAUTION
for surface cleaning. Follow the manufacturer's
instructions
disinfecting agent.
Damage to the product due to inappropriate
cleaning/disinfecting agents
temperatures!
CAUTION
Use cleaning and disinfecting agents according
to manufacturer's instructions. The cleaning
and disinfecting agents must be
- approved for plastics and high-grade steel.
Observe specifications regarding concentration,
temperature and exposure time.
Do not exceed the maximum allowable cleaning
temperature of 55 °C.
Do not clean the handpieces and attachments in an ultrasonic cleaning
bath and do not immerse them in any fluid.
To avoid the risk of corrosion/malfunctioning, allow any fluid in the
product to drain out immediately.
For the tools, apply ultrasonic cleaning
– as an effective mechanical supplement to manual cleaning/
disinfecting,
– as a pre-cleaning procedure for products with encrusted residues, in
preparation for mechanical cleaning/disinfecting,
– as an integrated mechanical support measure for mechanical
cleaning/disinfecting,
– for additional cleaning of products with residues left after mechanical
cleaning/disinfecting.
