Lol, I did that, I shat myself staring at it. A way of helping to prevent it, is to run the PC at max load for a while, and then be quick to get it off while it is still warm. (The pc off when you take the CPU out.)
Is there any pins broken, as they will have to be straightened.
The goo gone is that liquid, it is the isophyll (90+% alcohol would do btw.)
I was able to pull the CPU off of my heatsink, having half the thermal pad on the CPU.
