The Soniscrub Ultrasonic Cleaning Process

Treat your instrument to Soniscrub, the safest and most effective deep cleaning system for your brass or woodwind instrument.

Here's how it works

The magic and power behind the Soniscrub process is ultrasonic, or high frequency, energy. When waves of ultrasonic energy are introduced into a liquid, a negative pressure is set up, causing what is known as cavitation. Cavitation creates micro-bubbles that move around in the waves, and as these waves continue to be generated the bubbles get larger and more unstable. Ultimately, these bubbles collapse and implode, releasing high-powered shock waves at the rate of about 40,000 times per second at about 10,000 degrees F, breaking away unwanted contaminants and debris from the surface of your instrument. It is the cavitation implosion that is the secret behind this highly effective and safe deep-cleaning process.

Is it really safe?

Absolutely! Remember, while this process may sound a bit violent, it is occurring at the microscopic level and for a relatively short period of time. It is a gentle process and each instrument is handled individually. If there is any potential risk to your instrument, you will be informed before any work is done.

The machine is specifically calibrated to provide only enough energy to remove buildup and debris. The solution used is primarily water with a small amount of a specially engineered environmentally friendly additive. We use 80 gallons of water to one gallon of the low concentration additive designed to remove scale. We have complete control over the process and go to great lengths to ensure that your instrument is kept safe. 

What does this mean for my instrument?

Here's one way to think about it. The difference between a medium and large bore diameter in a trumpet, for example, is only about 0.003" Unwanted buildup in the instrument can typically range from 0.002" up to about 0.006" and beyond! This debris and residue can, in fact, effect the timbre, intonation, and response of your instrument. Our ultrasonic cleaner has the remarkable ability to deep clean even the hard-to-reach places that conventional cleaning process' and brushes can miss entirely.
