Cleaning and Restoring a Badly Corroded PSU

I don't see why you have assumed that one of the capacitors has leaked. The corrosion could have come from water or condensation onto the board.

I don't see any corrosion on the components.

Subject: Cleaning and Restoring a Badly Corroded PSU

I am now looking at the H7826 PSU that came with a TURBOchannel Extender. It
looks like there may have been capacitor leakage and some heatsinks will
need to be replaced. I have posted pictures here:

So two questions:

1.       Any suggestion on how to clean the board? Some of the corners are a
bit inaccessible to reach with just a cotton bud and isopropyl.

2.       Do those heat sinks have a particular name/spec that I can search
