The ultrasonic cleaner generates high-frequency sound waves that create microscopic bubbles in the water. These bubbles gently agitate and lift dirt, oil, and grime from the surface and crevices of your items, providing a deep, thorough clean without abrasion.

This cleaner is safe for a variety of items, including jewelry (like rings, earrings, necklaces), glasses, watches (without leather straps), metal utensils, makeup brushes, and other small household items. However, it is not recommended for soft or porous gemstones (like pearls, opals, and emeralds), as they may be sensitive to ultrasonic vibrations.

A standard cleaning cycle takes about 3-5 minutes. For items with more stubborn dirt, you may run an additional cycle. Just ensure you don’t leave delicate items in for too long to avoid unnecessary wear.

The cleaner is safe for most metal jewelry, including gold, silver, and platinum. However, it’s best to avoid using it on porous gemstones (e.g., opals, pearls) and fragile materials, as these may be sensitive to ultrasonic vibrations. Always check your item's care instructions if unsure.

Yes, the 450ml capacity allows you to clean multiple small items at once. Just ensure there’s enough space between items so they can be thoroughly cleaned and avoid overcrowding.

It depends on the type of item and how often it's used. For example, glasses can be cleaned weekly, while jewelry can be cleaned every 2-3 weeks, depending on wear. Regular cleaning will help maintain your items in pristine condition.
