I'm horrible at cleaning circuit boards, I use IPA mostly and Q-tips but I'm never happy with the results. I recently started working on an Onkyo A-5 and found this old blast from the past and it's still on the net. This guy has some great advice on how to properly clean a circuit board, I haven't used it yet but will be getting all of his stuff soon, I have a lot of audio with roached boards, can't wait to try this out.
