[Milsurplus] Way OT: Is soot corrosive?

[joldenburg2 at new.rr.com]

One additional item. For cleaning soiled pc-boards I have had great luck with isopropyl rubbing achohol and a distilled water rinse.

Soot is the product of incomplete combustion...  not enough oxygen... and
is essentially very finely powdered carbon (lamp black).

However, in practice, it is not pure carbon. It is often oily and those
oils may absorb other combustion products. The oil makes the soot stick.

I'd try one of two things:

Fantastic on things that can get wrt (NOT transformers, speakers, etc)

Rubber Cement Thinner on other surfaces.

I'd not try to scrub it off, as that may make matters worse.

FWIW,
