That instantaneous collapse focuses all that kinetic energy into a microscopic point, creating a high-speed liquid “micro-jet” moving at incredibly high speeds, along with intense, localized heat and pressure. And because the bubbles are smaller than the thickness of a human hair, roughly 75 to 100 microns, they can reach directly into the grooves, harmlessly blasting away embedded dust, mold, oils, release agents, and any other debris, a feat no brush or vacuum pad can begin to match!
