I would use amtech flux and not liquid flux, that runs off too easily.

For cleaning the board isopropyl alcohol is a good idea. Preferably above 95%.

You would need to reball all ICS to ensure they contact the board correctly.

But I don't see the worth in doing this to get a working logic board.
