Common Uses

Personal Care: Ideal for eyeglasses, sunglasses, razors, toothbrushes, and combs.

Jewelry: Effectively cleans rings, earrings, necklaces, and bracelets made of precious metals like gold and silver.

Dental Hygiene: Frequently used for sanitizing dentures, retainers, and mouthguards.

Professional Tools: Suitable for manicure and cosmetic instruments, such as nail nippers, files, and brushes.

Other Small Items: Can be used for waterproof watch bands, coins, small metal parts, and keys. Basic Operation

Fill the Tank: Open the lid and fill the stainless steel tank with water. Ensure the water level is between the "MIN" and "MAX" lines.

Add Items: Place your jewelry, glasses, or dental appliances into the water. For best results, items should be fully submerged but not overcrowded.

Optional Cleaning Solution: For heavily tarnished jewelry or greasy glasses, add a few drops of mild dish soap or a specialized ultrasonic cleaning concentrate.

Select Cycle: Depending on your specific model, select a timing cycle (typically 3, 6, or 12 minutes).

Start: Press the power button. You will hear a buzzing sound, which indicates the ultrasonic waves are creating "cavitation bubbles" to scrub the items.

Rinse & Dry: Once the cycle finishes, remove your items, rinse them with fresh water, and pat them dry with a soft, lint-free cloth.
