If I were in your position I would definitely replace that socket rather than try to refurbish it. That said, it's easy for me to say when I have invested in all the right tools for doing this sort of work.
Desoldering a DIP socket properly can be a bit tricky. But given that the part is scrap anyway, there's no need to desolder it "properly". Here is an improper method that will work and will be easier for you:
Carefully cut away all the plastics to free each pin from its neighbour. Now, to desolder, you can simply apply sufficient heat to each joint in turn and carefully pull the pin out. Now, there are two important things here:
- CAREFULLY cut the plastic. Don't wrench and bend it. Use good, sharp tools. Don't damage the PCB!
- When removing a pin, apply sufficient heat and fresh solder. If the pin still won't come easily, find out why rather than force.
This will be relatively simple for you to do with only basic tools required. Of course, the DIP socket will be completely destroyed but we are not trying to salvage it anyway.
If you still feel like you can't do it then you can try the cleaning method previously offered by blindguy. If this was going to be my strategy I would clean thoroughly, then replace the IC, and I would take a resistance measurement from the solder-side to the shoulder of each pin on the IC. Expect a low resistance. High resistance means your cleaning has been unsuccessful.
I don't suppose you're located anywhere near South Wales, UK? If yes I will happily meet up and help you save this AMIGA.
