How To Wash a Dirty Circuit Board - Industrial Electronics Repairs

[michaelmorrison]

Wash it with water and soap..(If you're doing a video you might want to find out what you're using) After you wash it blow it off with medium velocity air and THEN immerse the entire unit in IPA ..Alcohol.. The alcohol breaks down the remaining H2O's surface tension allowing to to evaporate far more readily..By the way. There will be a residue after alcohol. No worries. Inert.

My left ear learned how to clean a PCB. Thanks. :)

I'm surprised you were able to get all the water out afterwards, but I've also heard of people successfully cleaning their PCB in the dishwasher, so it must be possible.

Thx 4 the video, I learned more from the ads.

I believe it's an acid, you brush it on, it foams up, then your wash it off. Got it.
I saw my neighbor clean his Subaru the same way...but he kept the brush and took hours.

Ok I just bought a new pressure washer and have been looking for stuff to clean with it so I think I will pull the old 65 inch tv off the wall and take it apart and hang it up on the clothes line and test this shit out.

If board components are waterproof then this method well may be ok but not safe. This board has standard electrolytic capacitors. Capacitors have holes for legs, all covered with rubber but water potentially can creep inside cause a short circuit, even if you dry it, keep it warm, blow with air, etc. In this case, every micro hole in electronics could damage electronics. That's why you want to use cleaners that evaporate instantly for example isopropanol alcohol 99

I only have a shop vac, no air compressor. I baked the circuit board at 120F in my toaster oven until it dried. IT WORKS! I did not know before today that I could clean electronics with water.

I think it is a big mistake to rinse with water. There are usually mechanical relays that are not water proof, for example.

My left ear learned to clean mother board, while my right ear listen to music

[rontaylor]

its 90 degrees plus outside and its already going to be on the clothes line just in case the water gets into places that are hard to dry out.
this should work and its too big to put in the clothes dryer. ( Im not going to use the washing machine or the dish washer to wash it so why use the clothes dryer anyway )

I wish you had mentioned what kind of cleaner this was and what the process was after spraying on the board

[westbay]

What about. 99% Isopropyl rinse instead of pure water? Then it evaporates on its own with no residue.

[roceloi]

I use wd40 contact cleaner or normal wd40 and always has work for me, one time I restore a wet pcb using wd40!

[westbay]

What dilution rate on this Cleaner was used? Thanks

[DontFuckWitDreDay]

is he seriously rinsing the circuit board with WATER???

[dogeymon]

Thanks. I got a Sega CD console recently for free….except it smells like roaches. 🤮 I’m gonna need to clean everything

[stephen]

I don't think I want to try that on my vintage amp

[enricoderojassarson]

I was always taught to clean electronics with grain alcohol

[jimmycake]

you aint getting all that water out. it wicks into wires. all you prob needed was a vacuum cleaner and brush,

[adrianTNT]

Don't some capacitors and relays have cardboard in them ? Between coils and so ?!
