How did you clean off the battery acid?

Subject: [vintagesynthrepair] Korg POLY-61 pitch drift problem
Hi, I'm trying to repair a POLY-61 for a friend. I have very little experience at this.(I replaced the battery in mine so he thinks I'm a genius). Anyway, I replaced his battery,but some of the ni-cad acid found it's way across to the voice board. I had to replace a transistor and some other things. I thought I had it right, but after a few minutes voice 2 and 3 begin to drift up in pitch to no end. I don't know if I used the wrong parts or if something else is wrong. Any ideas?

That happened on a Korg Trident II for me and I had
to re route some of the PC board traces with wire because it fried the
board.
