First I want to thank one of my subscribers, William, for prompting me to put this post together. So let’s just jump right in.
Ultrasonic cleaners are typically used to clean things like jewelry and eyeglasses, but they’re also used for medical equipment, electronics, musical instruments and other things. Ultrasonic cleaners don’t sterilize though, so they won’t work like an autoclave in a tattoo shop (which many people wrongly assume).
How Ultrasonic Cleaners Work
Ultrasonic cleaners work by emitting ultrasound sound waves, which are sound waves that humans can’t hear. People with good hearing might be able to hear sound waves up to 20khz, but not usually higher than that. Ultrasonic cleaners typically run between 25khz to 400khz, so we can’t hear the sound they are emitting. Cats can hear up to 79 kHz and dogs up to 45 kHz, so you might notice your pets acting a little strange when you run an ultrasonic cleaner.
