Can anyone give me tips for removing old soot from a figure? Specifically, an old Kenner Power Of the Force Star Wars figure. So far I've tried scrubbing with dish soap, soaking in soapy water overnight, and soaking in Coke. I read somewhere that soaking in Alka Seltzer may do it, but I haven't had the change to try it yet. Scrubbing with dish soap got most of the soot off, but there's still a stubborn amount clinging to the top of the head, center of the chest, and arms/hands. Either that, or it's stained, I can't tell.
Barring that, will I be able to paint over the soot effectively? Has anyone tried it before?
This is in preparation for my first custom. Looking forward to getting into the hobby!
