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 ingredient: aldehyde,
alcohol) should be used.
Excessive doses of neutralizers or basic detergents can
cause chemical deterioration and/or fading of the laser
engraving on stainless steel.
Residues containing chlorine or chlorides, as contained
e.g. in surgical residues, tinctures, medicines, saline
solutions, service water used for cleaning, and in
cleaning/disinfecting agents, cause corrosion damage
(pitting, stress corrosion) and thereby destruction of
stainless steel products. To remove such residues, the
products must be rinsed sufficiently with fully
desalinated water and dried thoroughly.
Only use process chemicals recommended by the
chemicals’ manufacturers as effective cleaning/
disinfecting agents compatible with the materials used
in the respective product. Strictly observe all
application instructions, e.g. regarding temperatures,
concentrations, exposure times, etc. 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, the application/process solution only
needs to be of pH > 8 to cause visible surface
changes or
• Material damage, e.g. corrosion, cracks, fracturing,
premature aging or swelling.
• Do not use process chemicals that cause stress
cracking of plastics such as PPSU, or attack and
cause brittleness e.g. of silicone softeners.

Clean the product immediately after use.
Encrusted debris on HF instruments is softened
most effectively and conservatively by 5 minutes
immersion treatment in a 3 % H

solution.
Encrustations can be removed by hand, with a soft
brush. After that treatment, proceed through the
normal steps of processing.

material-/value-preserving reprocessing can be
found at www.a-k-i.org, Publications, Red
Brochure – Proper maintenance of instruments.
¾
Use suitable cleaning/disinfecting agents if the
product is put away in wet condition. Prior to
mechanical cleaning and disinfecting, rinse the
product thoroughly with running water.
Preparations at the place of use
¾
Open jointed products.
¾
Remove visible residues as completely as possible,
using a lint-free, single-use cleaning tissue.
Preparation prior to cleaning
¾
Have the product dry in a disposal container and
ready for immediate cleaning and disinfecting
within 30 min after use.
