This method of cleaning is far more effective than scrubbing, soaking and steam cleaning. It's powerful enough to remove heavy oils, waxes, or proteins, penetrating enough to deflux circuit boards and SMDs, yet gentle enough to clean tiny precision components and assemblies. Ultrasonic sound waves moving though a cleaning solution, create an effect called cavitation, the rapid formation and implosion of microscopic bubbles.
Heat enhances the process.
The deep-cleaning action of ultrasonics removes even the most stubborn dirt and contaminants, in the most inaccessible places.
