I've just bought an ultrasonic cleaner and wonder what the fluid of choice is? Isopropyl alcohol was my first thought.

I mix hot water with Dawn dish detergent and a little bit of 99% IPA @ 50 to 60C. -
Thanks, that should be easy to produce.Comment

That's are also cleaning fluids specifically formulated for the task.
Not sure IPA is a good idea because you'll get a lot of fumes."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Can you recommend one?Comment

Louis Rossmann recommends Branson EC

I've never used it, seems to be a specifically formulated detergent
CapLeaker's suggestion is probably cheaper"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

That one sounds good but with shipping to the UK it becomes expensive.Comment

As a question, is it un-recommended to clean certain parts in the ultrasonic cleaner ? Was thinking of trying to use one to remove some/a lot of sticker glue from some older cpus...Comment

I don’t even use the ultrasonic cleaner for removing sticker glue. 99% isopropyl rubbing alcohol or acetone makes that squeaky clean.Comment

Since they are old cpus ( Socket 462 and Pentium 3 time ) , I will try with acetone and see how it works. Not a big loss if the chip ends up dissolving
But the sticks and glue are from the "Warranty Void" kind, so it is stronger. Will try to take some pictures to post here.Comment

to remove sticker glue cheap & fast, just use white spirit.
it also desolves the pink or gray thermal gum used by some companies to put heatsinks on graphics cards and motherboards.

The main ingredient is 70-80% Monoethanolamine. "It is used in laundry detergents, hand and dish washing detergents, degreasers, hard surface cleaners and multifunctional detergents and disinfectants."
Ultrasonic cleaners are very hard on electronics, don't leave stuff in the bath a long time. They actually etch the metals. Semiconductor IC bond wires, quartz crystals breaking I have seen. I have a 60-90 second max.
For glue or adhesive I would expect it to do nothing because the glue just flexes. If IPA does not clean that off, then strong solvents like acetone I use with a Q-tip.Comment

CDS‑200B ultrasonic cleaner - AKA James Ultra 7050 etc.
There are many versions of cheap Chinese ultrasonic cleaners, and a fair few share this design, with a removable tank with handle. There are also fixed tank versions which look to use the same basic layout and presumably the same PCBs.
I picked one up "spares or repair" on ebay, and the cleaner was dead, but the fuse wasn't blown.
A quick diode check revealed D7 was shorted. D7 is a 12V 1/2 Watt Zener. I had one in my stash, so this was about as close to a "five minute repair" as...06-23-2025, 03:22 AM -
Hello All,
I wanted to check with the board before I do anything foolish and/or irreversible. Can someone please set me straight on the use of isopropyl alcohol to clean electronics? I understand it is commonly used to clean electrical contacts. However, in this case, I am wondering if I can safely immerse a small electronic item in alcohol provided a) all power has been removed and b) I take care to dry it thoroughly before re-applying power.
The short version is that I am seeking to clean an older used (well-used) electronic item. The basic plan is to immerse it in... -
I bought an ultrasonic cleaner from ebay and after a couple of years it blew one of the driver boards fuse and a couple of diodes. I replaced the parts and it worked for a while then died again. Since then I have thrown out the board and just use one. The unit had 2 drivers and the good one drives 1 transducer only. The fried board was driving 2 transducers. The unit works on 1 transducer but is weak in power. I am tempted to connect the 2 transducers that were driven by the dead board. And leave the single disconnected. Not sure if it there is a fault in them and will just kill the driver. As... -
Hi!
I would like to know which one is better for cleaning up soldering flux from pcb after soldering?
One option is 99.8% isopropyl alcohol
Other option is 70% isopropyl and 30% ethanol mixed together solution.
And also what would be the process? Do I just put it on pcb and let it evaporate or should I wash this off once it absorbed all the flux?
I also read that isopropyl is bad for pcb, but I am not sure what to think of it or what other alternative to use in that case? -
After a not very cool noise and the display dimming my ultrasonic cleaner powered off. The display and fan work, just nothing happens when I press the ultrasonic button.
I think it's at least the triac that is at fault (on the small PCB), showing 57 ohms between pin 1 and 3 and possibly one of the relays (marked in red), I was hoping someone might advise. Thank you....
