I've just started recapping my P475. I've removed the old capacitors-two had started leaking, but I haven't bought any new ones yet.

Fortunately, I caught the two bad ones just in time. I managed to scrape the gunk off with a pair of tweezers, and no tracks were damged. The unfortunate thing, however, is that there appears to be some stuff stuck underneath the neigbouring IC (the capacitors, for those familiar with the P475's board, were the two 100 uf ones). I'm worried that the tracks underneath it will be damaged, and my soldering is only just good enough for capacitors-no ICs yet!

What is the best thing to clean it with, as, of course, I can't get the tweezers under there?
