Ultrasonic cleaners use high-frequency sound waves to create tiny bubbles that collapse against instrument surfaces, dislodging debris from serrations, joints and crevices. Used correctly, they are safer and more effective than hand scrubbing.
Do
- Use a dedicated ultrasonic solution made for instruments, mixed to the correct concentration.
- Degas fresh solution by running the cleaner empty for a few minutes before first use.
- Open hinged instruments so cleaning reaches the joints.
- Use the basket or cassettes — instruments should not rest on the tank floor.
- Fully immerse instruments below the solution surface.
- Follow the recommended cycle time (often 5–15 minutes depending on the unit and load).
- Rinse thoroughly after cleaning to remove loosened debris and solution.
- Change the solution regularly — at least daily or when visibly dirty.
- Keep the lid on during operation to reduce aerosols.
Don’t
- Overload the basket — crowded instruments shield each other.
- Mix metals carelessly — chrome-plated or dissimilar metals can cause electrolytic marking on stainless steel.
- Put hands in the solution while the unit is running.
- Use household detergents or disinfectant solutions not designed for ultrasonic use.
- Clean mirrors and delicate instruments carelessly — follow manufacturers’ instructions for coated and optical items.
Testing your ultrasonic
Run a foil test or use commercial test strips periodically to confirm the unit is working evenly across the tank.
After cleaning
- Rinse instruments.
- Dry completely.
- Inspect under magnification for remaining debris.
- Lubricate hinged instruments.
- Package and sterilise.
Using cassettes makes ultrasonic cleaning faster and safer. Aurix kits are supplied in sterilisation cassettes.
