Ultrasonic cleaner
Appearance

We have an ultrasonic cleaner for base use.
The front has two knobs: temperature control on the left, and a timer on the right.
The knob on the left will control the built-in heater, using which is entirely optional.
The knob on the right acts as a "microwave style" timer that can be set to between a few minutes and 30 minutes.
Caution: never turn either the heater nor the ultrasound on with the basin empty - if there's no water, it is not safe to turn on!!!
No need to ask anyone to use. Please leave it running in areas away from people as the machine is very loud and annoying.
