Default Re: Cleaning and repairing a Corroded computer board

I routinely wash arcade machine PCBs whole. They are often filthy and have been badly stored, sometimes in damp conditions. Hot water with washing up liquid it and a decent scrub trying to avoid damaging any labels does the job. Then it needs a very thorough rinse, then drying promptly in a warm place with the board vertical, turning it round from time to time to allow any water trapped under components to escape and evaporate.

Don't worry about removing components unless there are PCB tracks under them that might need repair. The chances of damaging any of them by static discharge are slim, since water with detergent in it is pretty conductive.
