I just bought a used custom-built computer locally. In the process of checking the hardware, I notice that the case fans have accumulated a lot of green "gunk" and I've tried wetting the edge of a paper towel to wipe and rub it off. Still, there is always some residue remaining. What's the best way to clean off this gunk?

Thanks in advance. No pictures, but I can take some if needed.

Green?! That's a new one... – Ignacio Vazquez-Abrams Apr 17 '10 at 20:04
Yes... DARK green. I had to spend nearly 2 hours cleaning out the case and other components. – Wesley Apr 17 '10 at 20:11

Rubbing alcohol is an excellent gunk remover, no matter what color.

Hmmmm... I never thought of that. I'll definitely give that a try. – Wesley Apr 17 '10 at 20:10
My dad suggested Vim first, and it worked for the most part. Used rubbing alcohol after and it's perfect! Thanks. – Wesley Apr 18 '10 at 21:21

I use cotton buds to clean the dust off them, it can get right into the corner.

What are earbud things? – Josh K Apr 17 '10 at 20:47
oops, I meant cotton buds – Jonathan. Apr 17 '10 at 20:54
like q-tips? they're kinda like earbuds... i mean, they both go in ears, right? – quack quixote Apr 17 '10 at 21:38
Oh, q-tips.... right. – Josh K Apr 17 '10 at 21:53
Good point, but adding some liquid "solution" will make it work even better. I ended up using Vim for the first stage and then some rubbing alcohol and it is squeaky clean! Except that I cracked a corner when screwing it back on. >.< – Wesley Apr 18 '10 at 21:20
