Ultrasonic cleaning — particularly that which involves cleaners that operate at the high and low ends of the ultrasonic spectrum — is truly coming into its own with each passing day. Industrial ultrasonic cleaners look somewhat like over-sized washing machines, and they can clean virtually any non-porous object that fits inside of them, from jewelry to musical instruments.
Bench-top and tabletop models can clean smaller but vital objects ranging from saw blades to surgical instruments, and can provide the same level of cleaning to everyday objects.
The lower end of the ultrasonic frequencies is highly effective at shaking loose dirt, soil, salt, sand, and other particulate from a surface. The mid-range will remove grease, oil, and other adhesive materials that normally only come off with harsh soap or other cleansers.
The highest frequencies the machines can reach — on the order of 130 kHz — will clean electronic devices in preparation for being assembled in a clean room.
Early ultrasonic cleaners suffered from a problem of dead spots — areas where there was no cleaning action due to the wave patterns exactly canceling one another out. Many objects also had complex geometries that created large internal areas where no vibrations could reach. Today’s ultrasonic cleaners solve both problems by varying their waveforms slightly over the course of the cleaning, effectively moving the dead spots around so that every surface is properly cleaned and finding the right waveform for every internal area.
Modern ultrasonic cleaners also generally feature a temperature-control option that allows you to set the internal temperature of the cleaning chamber to a range between 85 and 175 degrees. The hotter the temperature, the more effective the cleaning process. However, because many electronic and other components are thermally sensitive, the option for a ‘cold clean’ is a vital one.
