FAQ – Ultrasonic Cleaning

1. What is Ultrasonic Cleaning?

Ultrasonic cleaning is process that uses sound waves (ultrasound) between 20-499 kHz to clean. The parts are placed in a solvent bath (usually just water) where they are exposed to cavitation bubbles induced by the high frequency pressure waves which work to agitate contaminates free from surfaces. The process is great for penetrating blind holes, recesses, and cracks where brushes, picks, or rags fail.


2. Will Ultrasonic Cleaning damage my parts?

With certain cautions, ultrasonic cleaning is considered safe for most parts. While the effects of thousands of implosions per second is very powerful, the cleaning process is safe since the energy is localized at the microscopic level. The most important cautionary consideration is the choice of cleaning solution. Potentially adverse effects of the detergent on the material being cleaned will be enhanced by the ultrasonics. Ultrasonic cleaning is not recommended for the following gemstones: opal, pearl, emerald, tanzanite, malachite, turquoise, lapis and coral.


3. What is cavitation?

Cavitation is the rapid creation, and destruction, of tiny little vacuum bubbles or “cavities” in a liquid. “How on earth does that clean anything?” you may ask. Well the process is rather interesting. These little microscopic bubbles, when forced into contact with a solid surface, collapse. When they collapse, the surrounding liquid fires into the area the bubble once occupied, which creates an intense “scrubbing” action as the cleaning solution rushes against the object being cleaned. Just imagine it as millions of microscopic pressure washers blasting the object from all angles at once!


4. What size parts can we clean?

At the moment no parts larger than 19”x11”x8”. For larger volumes of work provisions can be made so just ask.


5. How is it that electrical parts can be cleaned?

As long as the part is given enough time to dry before powering on again then no damage will be caused to circuitry.
