How can I clean the TB core from thermal compound

[Pitspawn]

Since I've destroyed my mobo and psu I need to know how to put my old 1.1Ghz into another mobo. I've been told that Isopynol alcohol stuff should do the trick. So I went down to a computer hardware specialist and he told me that the stuff that cleans video cassette heads has it in. He told me that once applied I shouldn't need to wait long after cleaning the core as this stuff evapourates quickly. He also says that Isopynol alcohol is a de-fatter, which means a no-no for getting on skin as it will make rashes etc.

I've bought some off this stuff now, and I've read that cleaning the core with cotton buds should be ok.

Will this work ok with TB core and say cleaning a GTS2 core?

I have never had to remove the pinkish 'bubble gum' from a Cpu die, or heatsink after it has 'baked on'. I use common fingernail polish remover to rid my heatsink bases of the evil TIM(Thermal Interface Material). Arctic silver recommends the following
procedure (http://www.arcticsilver.com/arctic_silver_instructions.htm), which does indeed use isopropyl alcohol. I use it only as a final wash.

In order to clean the epoxy from your GTS2 core, extremely cautious use of a razor blade and gentle scraping is advised, try to get all of the epoxy off. Be careful not to dig into the GPU. The epoxy should scrape and flake off fairly easy.

Once you remove all of the epoxy, clean the surface of the GPU. Get out the isopropyl alcohol and wipe off the surface of the chip. Make sure the surface is clean.

Proceed slowly and carefully.

If you haven't yet removed your heatsink from your graphics card, try putting it in a anti-static bag, tape it, and stick the contents in your freezer for a half-hour.This can make the heatsink removal a lot easier. After cooling, slip a credit card between the GPU and heatsink. Next, get a flat head screwdriver and place it between the credit card and the heatsink. Then, gently twist the screwdriver and the heatsink should pop off. The epoxy isn't very strong so this should not be too hard.

EDIT: I have links with photographs concerning the preperation of the graphics processor. If you are the least bit uncertain as to how to proceed, just ask and I'll provide them.
