Efficient 42 KHz Ultrasonic Cleaner Why you need it Deepcleans delicate items quickly and safely. 42 KHz ultrasonic waves create millions of microscopic cleaning bubbles that loosen and remove dirt, oils, and grime without abrasive scrubbing, helping restore valuables to a refreshed condition without damage. Saves time and effort compared with manual cleaning — ideal for routine maintenance of small, delicate items. Key benefits and features 42 KHz ultrasonic cleaning: Produces powerful microscopic cavitation for effective, nonabrasive cleaning. Gentle on valuables: Designed to lift contaminants without scratching or degrading most small metal, glass, and hardsurface items. Precise time control with auto shutoff: Choose a preset cleaning duration and the unit will automatically turn off when the selected time finishes (range 90 to 720 seconds). Touch control panel: Smooth, responsive touch buttons that are more stable and durable than ordinary mechanical switches. 12 preset cleaning cycles: Select from 12 time options to match the material and soil level — 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 540, and 720 seconds. Compact and portable: Small footprint and easy to store or move. Dimensions: 7.9' x 5.5' x 5.4'. Performance and practicality Fast, repeatable cleaning results tailored by time setting; use lower settings for light cleaning and longer cycles for heavily soiled items. Stable touch controls and automatic shutoff reduce wear and provide consistent operation over time. Compact size makes it suitable for countertops, workbenches, or travel without taking up much space. Typical use scenarios Jewelry maintenance: Quickly remove everyday oils and residues from rings, necklaces, bracelets, and earrings so pieces look refreshed before wearing or storing. Eyewear and small optics: Clean eyeglass frames and lenses, sunglass frames, and small optical components where gentle, thorough cleaning is needed. Hobby and smallparts cleaning: Remove dirt, grease, and particulate from watch bands, coins, small metal tools, and precision parts used in electronics, modeling, and repairs. What to expect Reliable, efficient cleaning for many small and hobby items using the 42 KHz ultrasonic process. Controlled, userfriendly operation through the touch panel and preset cycles with automatic shutoff. A compact unit that fits into small spaces and can be taken where needed.
