How ultrasonic cleaners work?
This method of cleaning appeared more than half a century ago, and you can read more about it here. But quite generally, you have ultrasound used to agitate fluid, usually water. Dependent on the item which you clean, you can add a solvent to enhance the process.
The whole process will last just a few minutes, but this will depend on the cleaned items and their state. This is convenient when you have tiny items like jewelry or coins.
The ultrasound generated in the process is at frequencies higher than our ears can perceive. So you have a generator (transducer) that creates sound waves in a water tank. These sound waves generate compression waves in the liquid and those result in millions of microscopic voids or bubbles. In physics they call this cavitation.
When the bubbles get in contact with the item in the liquid, they produce a sort of micro shockwaves and the energy generated in the prices dislodges contaminants. This is why such a method is without a match for tiny and intricate surfaces on jewelry, coins, and similar items.
Does ultrasonic cleaner kill bacteria?
The short answer is yes. This ultrasonic cleaning indeed kills bacteria and other pathogens. But note that this is through physical means and without any chemical process. This has been known for a long time and it has been used in dental molds.
Is ultrasonic cleaning safe for diamonds?
The answer is yes. The same holds for items made of platinum, silver, white gold and gold. But there may be some gemstones that you should not clean this way.
Is ultrasonic cleaning safe for users?
Yes, the sound frequency is typically in the range 20–40 kHz. In any case, make sure that you follow the instructions.
