Specs: Windows 7
ink from a printer cartridge leaked onto a circuit board with expansion slot that were uncovered what is best way to clean ink off and out of any unseen spots to salvage the board. no power has been run thru board since spill but some discoloration is visible in the card slots where expansion cards would plug in. ink was a straight black ink ( HP ) don't want to touch anything or try to use it until i can clean it a little concerned ink would or could cause electrical short inside when additional circuits are plugged back into slots. any suggestions on what to use to clean the ink off

✔ Best Answer
First be sure that absolutely nothing has power whenever you start to clean anything inside where electricity is present (sounds like you already know that). While most inks are water-soluble, Alcohol is likely the best agent to clean most inks, but use it sparingly. Use cotton-tipped applicators or if its a heavy spill, a small paper towel. It dries relatively quickly (within a few minutes), but make absolutely sure that you've not spread the ink to other locations in the cleaning process...

I would be concerned that alcohol might damage the
motherboard. On the other hand, if you can do the work
of removing the motherboard (which means having to
remove and re-install the CPU, which takes time and
care, as well as thermal grease), I see no reason not
to put the board under running water. Just get it fully
dry quickly, and don't use excessive heat. You can
probably even use a soft toothbrush on the ink.

Arctic Silver 5 thermal paste and their two-part cleaner
are what I used to put on a new CPU cooloing fan. I did
it very carefully so I only had to do it once, and it worked
well.

"I would be concerned that alcohol might damage the motherboard."

How? Unless there was something rubber built into it, no. Isopropyl alcohol is one of the most common cleaners in the industry, generally to clean solder rosin from circuit-boards after the hand-solder/solder-reflow processes.

Okay, I've damaged circuit boards, and I've damaged things
by using alcohol on them, but I can't say I've ever damaged a
circuit board by using alcohol on it. I mainly thought that trying
to clean up a large ink spill that got inside the PCI connectors
would take hours to clean by poking at it with paper towels or
Q-tips. Rinsing it under water, with a little brushing, could get
the ink off in minutes if it is indeed water soluble.

alcohol ie methylated spirits ... not splashed on but as mentioned with a fine cotton tip NOT roughly with wads of paper towel, avoid cafully knocking components, if it is a conductive ie salt or mineral based ink that is your only problem, if not only a problem if it is blocking connectors. any way in either case just clean where you need to no where else to avoid un necessary damage. And what the#$@$ where you doing with spillables near a bord in the first place?

Rubbing alcohol, but use the premium ones (98% Isopropel, not the ones that are watered down).
Q-tips and care. (be prepared to throw many away and double your plastic 'garbage' bag so the ink does not get on anything from the Q-Tips).
Go slowly.
And....
