Ways to remove black 'goop' over ICs on mass produced PCBs?

Is there a 'safe' way to remove the black blob of goop which is often
placed over mass produced ICs on modern PCBs?

I just want to faff around with a failing circuit on a festive LED
cluster/decoration. Basically it's a cluster of seven LEDs (two
yellow, two red, two blue and one green in the centre) that vary in
intensity - it looks like the IC is controlling the voltage to the
LEDs (and hence the intensity).

Thanks

Don't even bother. The 'goop' is there to protect the IC. You will simply
destroy it by removal.

Was wondering if that was the case. Ah well, ta. :)

-Eh, some epoxy remover might work. You'll probably lose the circuit board,
connecting wires and IC in the process though, I understand epoxy remover is
pretty nasty stuff. ;o)
