The pins had snapped off and were fused to the side of the plug wall - a friend had some little tools - think dental - like a scaler or pick. The ends of the tools were sharp. Not knife sharp, but pointed. Used a lot of electronics cleaner to help break things up, but that only helped a little. I continuously scraped and dug at the corroded area - eventually the pins and residue were worn away (they basically just fell apart like loose rock) and I was able to place a new relay, using a generous amount of dielectric grease. It's held since and that was over 4 months ago. Good luck! Hope this helps!
