What it does Combines a handcleanable design with a gearlike bottom structure to physically dislodge stains trapped in gaps and grooves. Uses sonic (soundfrequency) vibration for deep cleaning: vibrations loosen and remove dirt from tight seams, grooves and dead corners without harming the surface. Key benefits — why you need it Reaches places brushes and cloths miss: the gearlike bottom and vibration target narrow gaps and uneven surfaces. Deepcleaning action without abrasion: vibration removes grime without scraping or damaging delicate items. Easy to maintain: the unit can be cleaned by hand after use, so dirt and residue don't build up. Function and performance Manual contact plus sonic vibration for two complementary cleaning actions: mechanical agitation from the gearlike structure and microscopic agitation from sound vibration. Designed to remove embedded dirt from crevices, seams and hardtoreach corners while preserving the integrity of the cleaned object. Compatibility and use cases Suitable for items and surfaces with narrow gaps, grooves or tight corners. Typical applications: Jewelry, watch bands and small metal parts with intricate grooves. Cutlery, bottle caps and kitchen utensils with seams or serrations. Small household items and fixtures: keyboard keys, appliance seams, and other tight crevices. Practical advantages Reduces scrubbing time by targeting dirt that standard cleaning tools cannot reach. Minimizes risk of surface damage compared with aggressive mechanical cleaning. Simple hand cleaning keeps the tool hygienic and ready for repeated use. Combines targeted mechanical cleaning (gearlike bottom) with sonic vibration to remove stubborn dirt from gaps, grooves and dead corners while remaining safe for the cleaned objects.
