Sparklean® Professional Ultrasonic Cleaner — 40 kHz for jewelry & watches

The Sparklean Ultrasonic — Deep-Clean Where Spray Can't Reach Some grime hides where no cloth, brush, or spray can get to it: the prong settings on an engagement ring. The inside of a Rolex bracelet link. The hinges on a pair of vintage eyeglasses. The Sparklean Ultrasonic uses 40,000Hz ultrasonic waves to send microscopic cleaning bubbles into every crevice — lifting oil, lotion, hairspray, and skin residue out of places brushes can't physically reach. Best paired with Sparklean Original Spray: Add a few drops of Sparklean Original Spray to the 20 oz tank with warm water. The ammonia-free, pH-balanced formula cuts through buildup faster than water alone — and it's safe on every coating the ultrasonic touches. One 3-minute cycle does what 20 minutes of soaking can't. Safe for: Gold, silver, platinum, rhodium, brass jewelry Diamond, ruby, sapphire engagement rings (clean settings + back of stone) Stainless steel watches (Rolex, Omega, Tag Heuer — remove leather/fabric straps first) Eyeglass frames (without lenses installed) Metal coin and small collectibles Not recommended for: Pearls, opals, turquoise, emeralds — porous gems can crack Antique or fracture-filled stones Costume jewelry with glued elements Watches that aren't water-resistant — remove watch from band first; check seal rating Wood, leather, fabric, or coated electronics How to use: Fill the 20 oz tank with warm water (not hot) Add 3-5 drops of Sparklean Original Spray Place jewelry in the basket — don't crowd it Press the one-touch power button (3-minute cycle, automatic shut-off) Rinse with cool water, polish dry with the Sparklean Polishing Cloth What's in the box: Ultrasonic cleaner unit (20 oz / 600ml capacity) Stainless-steel basket insert Watch holder for cleaning watch heads Power cable (US plug; 220-240V option available) Specs: 40,000Hz frequency · 20 oz tank capacity · One-touch power · Auto shut-off after 3 min · 35W draw · Quiet operation (under 60dB) · Drainage spout 30-day money-back guarantee.
