[Milsurplus] Way OT: Is soot corrosive?

[Mark K3MSB]

A local ham had a small fire in his house and soot got over ( and in )
everything.   He wrote me

"I want to know if my ham gear is cleaned up will residue soot being
corrosive eat the boards."

He runs plastic Yaewoodcom type radios. I'd assume if soot is corrosive and
the boards in the radios lack conformal coating the answer is probably yes,
but that's a guess.

Any ideas?
