Product Information

About this item

• Powerful 50kHz Ultrasonic Deep Cleaning -- Urstand ultrasonic cleaner harnesses 50kHz high-frequency sound waves to generate billions of microscopic cavitation bubbles per second. These bubbles penetrate the tiniest crevices—between watch links, under prong-set gemstones, or around eyeglass nose pads—to dislodge embedded dirt and grime with precision. The higher frequency ensures gentle, non-abrasive cleaning, making it safe for delicate items like coated eyeglass lenses (when positioned properly) and fine jewelry.
• Effortless User-Friendly Operation -- Designed for simplicity—fill with water, choose your cleaning time (90/180/280/380/480 seconds), and press start. The unit automatically powers off once the cycle is complete, providing safe, hassle‑free daily cleaning for jewelry, eyeglasses, and watches.
• Versatile Multi-Purpose Cleaning -- Simply add tap water (or a few drops of ultrasonic cleaning solution for enhanced results) and let the machine handle the rest. Ideal for Eyeglasses, sunglasses, reading glasses (lenses facing up)—Jewelry: Rings, earrings, necklaces, bracelets—Oral care: Dentures, retainers, aligners, mouthguards—Personal items: Watch straps, razors, makeup brushes, baby pacifiers—Collectibles: Coins, small metal parts.(NOTE: Not suitable for oxidized silver, porous gemstones (pearls, opals), or items with loose stones.)
• Spacious 420ml 304 Stainless Steel Tank -- Designed with a larger 420ml (14.2 oz) capacity—exceeding standard 400ml models—this tank comfortably accommodates a full pair of eyeglasses, multiple rings, a watch strap, and dentures simultaneously. Crafted from food-grade 304 stainless steel, it offers exceptional corrosion resistance, ensuring hygiene and durability for repeated use with jewelry, oral appliances, and personal care items.
• Compact, Quiet & Travel-Ready -- Despite its generous capacity, the unit maintains a compact footprint with a sleek, lightweight design. Four non-slip rubber pads stabilize the cleaner during operation, while ultra-quiet performance ensures it won’t disrupt your workspace or home environment. Ideal for use at home, in the office, or while traveling.
