Ultrasonic Treatment

Effective ultrasonic cleaning requires placing the surgical instruments into suitable sterilization
trays or wire baskets in an open condition. As the use of plain warm water alone cannot
produce satisfactory results, it is necessary to add a suitable cleaning agent. Be sure to
observe and follow the manufacturer's instructions with regard to concentration as well as
temperature. Since an excessive dirt content of the cleaning solution has an adverse effect on
the cleaning results, the solution must be replaced at regular intervals in accordance with the
manufacturer's instructions. In the same manner, prescribed immersion or ultrasonic
treatment times must be strictly observed. As a rule, ultrasonic cleaning must always be
followed by a rinsing cycle. Be sure to check the instruments (where applicable) for loosened
components after the ultrasonic bath. To prevent water spots ("spotting"), fully demineralized
or distilled water should be used for the final rinse.

Chemical Disinfection

The solutions employed for chemical disinfection must always be used in accordance with
•
the manufacturer's instructions.
Never use hypochlorite-based disinfectants containing active chlorine (e.g. chlorine
bleaching agent (sodium hypochlorite) or Javel water) or disinfectants containing iodine.
• Pure water must be used for preparing the dilutions specified for the chemical
disinfectants. The addition of detergents is not permitted. The manufacturer's instructions
regarding exposure times and concentration must be duly observed in each case.
Disinfecting solutions must be prepared afresh every day. Extended/multiple use can easily
•
lead to the following problems:
— Increased concentration due to evaporation (corrosion risk)
— Excessive dirt load (corrosion risk plus lower effectiveness)
Following disinfection, it is important to rinse all items sufficiently under clear running
•
water. To prevent the formation of water spots, the use of fully demineralized water is
highly recommended.
Immediately after completion of the cleaning and rinsing cycles, surgical instruments must
•
be sufficiently dried.
