What Electronics Can Be Cleaned in an Ultrasonic Cleaner?
There are many electrical items that can be cleaned in an ultrasonic cleaner using a low pH cleaning solution without using deionized water in the ultrasonic tank. Rule of thumb for cleaning electronics: if the item has an LCD display, do not place the item in an immersion ultrasonic bath.
The following items, without a display, can be cleaned using an ultrasonic tank:
- Blow Dryers
And many more.
The cleaning procedure is as follows:
- Make sure the item is unplugged.
- Remove batteries – do not reinstall until the item is fully dry.
- Disassemble the item:
- If you’re unsure how to do so, please research the process online using a platform such as YouTube.
- Take photos while you are disassembling so you know how to put the item back together after it has fully dried.
- Clean all smaller items and screws using screen strainer in the ultrasonic bath.
- Once dry, place these items into clearly marked zip-lock bags or containers to avoid losing them.
- Do a primary and secondary rinse, of the larger pieces, with deionized water.
- Blow excess moisture off with air 50 psi.
- Use a drying chamber or rooms to thoroughly dry and deodorize the items (drying chamber works best) for 6 to 8 hours at 115° – 130⁰ F.
- Re-Oil any items such as gears and guides, if this fits your application.
- Reassemble the item.
- Plug in and power on the item to make sure that it functions correctly.
Using ultrasonics to clean electronics is very efficient and highly profitable. Ultrasonic cleaner waves are sound waves transmitted above 20,000 Hz (20 kHz or 20,000 cycles per second), or higher than the frequency detectable by humans. … These vibrations cause our eardrums to vibrate, which the brain then interprets as sound.
