Portable ultrasonic cleaner for small items
The Metra ultrasonic cleaner is a compact, white unit designed for household use. It measures 19 by 7.2 by 7 centimetres and weighs 190 grams. The 250 millilitre tank holds jewellery, glasses, dentures and similar small objects. A single button starts a five-minute cleaning cycle using high-frequency vibration.
Cleaning relies on cavitation in a small tank
The device emits 45000 Hz ultrasonic waves that create millions of microscopic bubbles. These bubbles collapse against surfaces to lift dirt from every angle. Because the tank holds only 250 millilitres, larger items such as bulky watches or multiple pieces cannot be cleaned together. The process requires tap water and does not use heated fluid or adjustable power levels.
250 millilitre capacity suits daily accessories
The internal volume comfortably fits rings, earrings, contact lenses, retainers and spectacle frames. It runs out of space for bracelets, necklaces or anything longer than the 19 centimetre interior. Users needing to clean larger volumes or heavier tarnish will find the single-cycle, fixed-frequency operation limiting.

Questions about this item
How do I decide which capacity version of this ultrasonic cleaner to choose?
This model comes in a single 250 ml capacity, so there is no version choice to make.
What does the 45000 Hz frequency actually do when the machine is running?
It drives the transducer to create millions of microscopic bubbles that implode and lift dirt from every surface of the items inside.
What interface or connection does the cleaner use and what limits it in practice?
It plugs into a standard mains socket and the single-button control limits operation to a simple on/off cycle with no adjustable timer or power levels.
