Give me one or two days, Sheila,
I'll see if I can give you some idea. We had a fire that cost us multum. We had to send a lot of instruments and PWBs to a company specialized in soot cleaning. Important is to perform ion test afterwards too see there are no remainings. The company made a very fast such measurement with a mobile equipment. We have Marconi people working here, maybe they also remember those bad days.

Hi TechNetters --

Anyone got any ideas/experience with cleaning (nondestructively!!) assembled
PWBs that were exposed to an electrical fire?  The boards are covered with
soot and associated black gunk.  They are conformal coated (urethane).  TIA.
