Ultrasonic cleaner

Ultrasonic cleaners are machines that clean things using sound waves. Have you ever heard a really high-pitched noise that almost hurts your ears? That's similar to the sound waves that are used in an ultrasonic cleaner, but they are much higher in frequency and you can't hear them.

When you put something dirty into the ultrasonic cleaner, it fills with water or a special cleaning solution. Then the machine sends sound waves through the water. These sound waves create tiny bubbles in the water that are so small you can't see them.

These tiny bubbles are called cavitation bubbles. They are powerful and can do a really good job at cleaning because they can reach places that a brush or cloth might not be able to get to.

When these bubbles collapse, they make tiny shock waves that can knock dirt and grime off the item you're cleaning. After a little bit of time in the ultrasonic cleaner, your item will be much cleaner and shinier!

Ultrasonic cleaners are used by lots of different people - dentists use them to clean their instruments, jewelers use them to clean jewelry, and mechanics use them to clean engine parts. They are really helpful machines that use science to make things clean in a really cool way!
